Courageous engagement

Skillful discernment and the principle of non-contradiction: Knowing how to make client-centered professional commitments among different ideas and practices

Many of us who attended junior high or high school in the United States had to read and analyze "The Road Not Taken", a poem published in 1916 by Robert Frost.

It reads:

1. The Road Not Taken

TWO roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;         5

Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,         10

And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.         15

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.         20

What emotions do you hear in the narrator's voice about having to choose between the two paths?

 

 

 


...sorry I could not travel both
And be one traveler...

 

Among other possible interpretations, one thing that come through is the narrator's regret at having to choose only one path, rather than being able to take both.

He does hold out the hope of coming back someday and taking the other one as well, yet he is realistic that it is unlikely that he will ever be able to do so:

...Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back...         15

 

To be able to embrace all ideas and opinions equally is a lovely idea in theory--but, throughout millennia of human history, including the ancient Indians and Persians as well as the classical Greek philosophers, no one has yet figured out a universally-accessible way to resolve the contradictions the attempt to do so creates in practice.

The principle of non-contradiction, on the other hand, seems to have withstood centuries' worth of challenges, at least well enough to serve as a general rule for evaluating whether claims have the potential to be the basis of sound clinical reasoning.

The principle of non-contradiction states that a claim cannot be true and false at the same time.

So an idea can be true, but if that is so, then its exact contradiction in every way cannot simultaneously be true as well.

Smiliarly, if the exact contradiction of the idea is true, then the idea itself must be false at that time.

Like the narrator in Frost's poem, we have to choose to take one or another, but we cannot take both at once.

 

Choosing whether we make our commitment to "This claim is true" or "This claim is false" often takes us in a direction opposite from the other choice.

 

 


Many MTs are among the nicest people that I've ever had the honor of knowing.

Lots of us don't like correcting or disagreeing with other people's ideas--we'd prefer for everyone to always be right, and to feel good about it.

Unfortunately, the natural universe doesn't work that way. The principle of non-contradiction, reinforced over centuries, means that the contradiction of a true idea must be false.

So, sometimes, we are going to have to practice skillful discernment, to distinguish among ideas that are right and those that are wrong.

Sometimes, because of episodes of oppression in history, we especially want to be sensitive cross-culturally and we don't want to echo that oppression by evaluating as right or wrong the ideas of someone else from another culture. Especially in light of the toll that colonial history and slavery took in Africa, those of us who are white Americans might be extremely hesitant to contradict beliefs that some Africans hold.

Yet, sometimes, as the healthcare professionals we aspire to become, sometimes we have to do so, for the sake of others' health and well-being.

The following case report illustrates such an idea that we have to stand up against, because it is unequivocably wrong:

Meel BL. 1. The myth of child rape as a cure for HIV/AIDS in Transkei: a case report. Med Sci Law. 2003 Jan;43(1):85-8. PMID: 12627683. The entire free fulltext PDF is available here, although you should consider whether you want to read about real-life sexual violence toward children before you click the link.

Source: Department of Forensic Medicine, Faculty of Health Sciences, University of Transkei P/bag X1 Unitra, Umtata 5100, South Africa.

Abstract: South Africa has one of the highest cases of HIV/AIDS infection in Africa, and Transkei, a former black homeland, now a part of the Eastern Cape Province, is one locality with a large number of HIV/AIDS sufferers. The unemployment level is very high and crime, including child rape, is very common. This report presents the case of a victim of rape, a nine-year old female child who was brought to the Umtata General Hospital, a victim of the mistaken belief that sex with a virgin will cure an HIV-infected person or AIDS sufferer of his illness. The alleged rapist was an HIV-positive uncle of the child. The myth of the 'HIV/AIDS virgin cure' is prevalent in the community. The history, physical examination and laboratory investigations of this case are given. A conclusion is drawn and preventive methods are suggested.

 

Of course, African countries are not the only place the virgin cleansing myth is found; I've encountered it in my massage work among Southeast Asian refugees as well. And here in America, where I am writing this, we certainly have our share of ridiculous, counterfactual, and damaging health beliefs, as well.

I chose this example, not to imply in any way that this is a uniquely African problem, because it's not--if anything, it's a uniquely human problem that we all share. We all risk falling into this trap ourselves, which is why we try our best to remain viglant against doing so.

I chose the African example for this reason: The history of the treatment of African people by American and European national powers has been uniquely and shamefully brutal on a sustained basis. One part of that horrific treatment was dismissing the subjugated people's empirical knowledge and other beliefs as "primitive", "wrong", and "pagan", among other epithets.

In light of that awful history, vowing to never again commit that particular brutality is certainly the right thing to do. We agree on that much.

What can be difficult is understanding exactly how to keep that vow.

It might seem at first that the way we do it is to keep silent as someone else expresses their ideas, no matter how different they may be to our own. After all, we agree that being tolerant is a desirable ethical behavior.

The problem with that approach is this: If we keep silent in order to be tolerant of African (and other places') belief in the virgin cleansing myth, then we stand silent as African (and Cambodian, and other) children are harmed by child rape in the material physical natural world.

If we keep silent in order to be tolerant of Burmese refugees' beliefs that malaria is caused by swimming, then we stand silent as Burmese people are harmed by failure to seek effective malaria prevention and treatment in the material physical natural world.

If we keep silent in order to be tolerant of the ultra-Orthodox Jewish tradition of "metzitzah b'peh, during which the mohel, or person performing the procedure, orally sucks the blood from the infant's newly circumcised penis", then we stand silent as two Orthodox Jewish boy babies in New York City die, and potentially thousands more contract or are exposed to herpesvirus infections in the material physical natural world.

If we keep silent in order to be tolerant of climate skepticism's disbelief in the science pointing to the ecological effects of global climate disruption, then we stand silent as the food supply, habitat, and lives of people and animals are put at risk with no contingency plan or mitigation in the material physical natural world.

If we keep silent in order to be tolerant of vaccine skepticism's belief in ill effects of vaccinations and the resulting drop in immunization rates, then we stand silent as babies, young children, healthy vibrant young adults, the elderly, and the immunocompromised are killed and left injured by preventable diseases in the material physical natural world.

If we keep silent in order to be tolerant of other massage practioners' claims (no matter how well-meaningly they were taught) that contradict biology, chemistry, and physics, then we stand silent as our clients--at some of the most distressed and vulnerable times in their lives--are confronted with the added cognitive burden of sorting out contradictory healthcare information in the material physical natural world.

If we truly want to evolve into the healthcare professionals that we often say we want to become, then--when the paths of traditional (or non-traditional, for that matter) practice or ideas necessarily lead to avoidable material physical harm to other people and animals--then we have to choose to commit to the path of practicing tolerance and beneficence by actively speaking up in the interests of people and animals against that harm, even at the expense of those ideas or practices.

If that goal is what we really want for our profession, then we have to choose the road less-traveled.

 

 

Massage in a biopsychosocial model

[reposted from Massage in a biopsychosocial model (#29/31)]

 

 


Psychosocial and cognitive approaches don't require that you become a clinical psychologist but that you have a broad concept of the influence of those factors and that you account for them in your encounters with your patients. Know the literature and be able to give management advice based on evidence. When people come to see you they want a plan. Have a plan that is defensible and that works toward their goals. Address concerns, fear avoidance, other stress, and unhelpful beliefs with compassion, understanding, empathy, and informed knowledge.

Understanding why people hurt is part of our professional responsibility and should change most everything we do on a daily basis away from traditional methods and towards methods defensible with modern science.--Jason Silvernail accessed 5 August 2011

 

Since I'm advocating massage in a biopsychosocial model, it's my job to connect the dots and explain what I mean by that.

A biopsychosocial model of health and illness is one that takes into account the role of biology (and other sciences), psychological factors, and sociocultural factors, as well as the interactions among those different factors, in seeking to understand what health and illness really are.

An example of a biological factor in health could be increased cortisol in the bloodstream in response to chronic stress. The interaction of that biological factor with the increased daily stress in modern society would be an example of interactions among biological factors and sociocultural factors.

An example of a psychological factor in health could be a man who is less likely to seek professional treatment for pain than a woman is, because of his perception that stoically enduring pain is what men do in the society he grew up and lives in. The increased structural damage that can occur as a result of ignoring symptoms and delaying treatment is an example of the interactions among psychological factors and biological factors.

An example of a social factor in health could be the relative stigmatization of mental or behavioral illness, as compared to how more clearly structural conditions are regarded. This stigmatization can drive psychological conditions underground--say, for example, if someone did not get needed psychological treatment because they didn't want it to show up in their medical record. That would be an example of interactions among sociocultural factors and psychological factors.

Biopsychosocial massage is client-centered. That means that the psychological and social factors in the client's unique experience, as well as the universal biological factors we are all subject to, is the center of where we focus our attention and caring. It doesn't mean that we accept everything in someone else's experience is literally true. It does mean that we recognize that, for them it feels true, and for that reason alone, it is important in where we meet the client in the therapeutic encounter.

Biopsychosocial massage welcomes self-expression and the art of massage. It is clear, however, that sometimes our need for self-expression can come into conflict with clients' immediate healthcare needs, and--when that happens--we recognize that, in order to act as healthcare professionals, our ethical fiduciary duty is to put the clients' needs first, ahead of ours if necessary.

Biopsychosocial massage is wholistic, integrative, and evidence-based. That means that it does not draw upon supernatural explanations of mechanisms, and it builds upon foundational knowledge in the sciences to evaluate and validate the evidence for or against particular claims of effectiveness or mechanisms.

Since our encounters with clients will always run ahead of the available high-quality evidence, we don't limit ourselves only to what has been rigorously validated by studies and nothing else. We take our professional experience into account, and we actively seek to understand and incorporate the clients' preferences, whenever possible, in treatment. But in all these cases, in developing our approach to caring for the client, we remain clear on what is evidence, what is speculation, what is science, what is art, what is literal, and what is metaphor.

Understanding the material physical universe around us, and the centuries of cumulative human knowledge about that universe, give us powerful tools to draw upon. That understanding, combined with the caring that characterizes so many people who choose to go into massage as a career, is the heart of biopsychosocial massage.

Neil deGrasse Tyson sums it up almost perfectly:

I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You'd be surprised how far that gets you.

--Neil deGrasse Tyson

 

That quotation demonstrates the core of massage in a biopsychosocial model.

Who owns BPSM?

That's an excellent question.

Diane Jacobs, talking about dermoneuromodulation (DNM)--a practice that she has developed, and that we'll talk more about here later--answered that intellectual property question first, and better than I could have come up with off the top of my head.

When asked:

What's a good name for working top down and bottom up?

 

she answered:

Dermoneuromodulation. :)smiley

It covers the manual territory from skin cell to self of self and leaves out the mesoderm entirely. It is not a copyright term.

Anyone can use it, to describe what they do, manually, if they want. This made-up word is not copyright. I give it away. Please take it. Use it to get away from words like "fascia" and "muscles" and "joints" and "bones" and "ligaments" and "tendons".

 

In the same way as Diane practices with regard to her development of DNM, I don't claim any restrictions on anyone's access to use of the term through copyright or ownership over the term "biopsychsocial massage (BPSM)".

I give it away to the community to use freely, in the same spirit of open access and Creative Commons licensing that POEM is founded on.

There is only one condition of usage--you cannot apply the term to something it is not, any more than someone can make a dog into a cat, just by calling it one.

In a similar way, you can't make non-BPSM practices into BPSM simply by slapping that label on them.

Diane explains that, although she gives the term away freely, that

It should contain only nervous system considerations though, because really, when push comes to shove, only the nervous system can respond (short term, OR, and ESPECIALLY, long term) to what we "do" to another person, manually. Of that I'm convinced.

 

Similarly, if you're not practicing biopsychosocial massage, the term does not apply to what you actually are doing.

You have every right under principles of freedom of conscience to reject classical Newtonian physics, for example, and to say that it does not apply to the work that you are doing. But that claim is inconsistent with the principles of BPSM, and so that inconsistency means, beyond the shadow of a doubt, that your practice is not a biopsychosocial massage practice. Which is fine in itself; you are entitled to practice any way you want to, subject to professional ethics and to regulations in your jurisdiction. All it really means is that you don't get to label it something that it is not--no more, no less.

There is a Cambodian saying that men are like diamonds and women are like silk--if you drop them in the mud, you can wash the diamond and it's as clean as it ever was, but the silk is stained forever.

«បុរសជាមាសទឹកដប់ ទោះធ្លាក់ចូលភក់ ហើយលើកមកវិញ ក៏នៅតែជាមាសទឹកដប់ដដែល តែនារីវិញ ប្រៀបបាននឹងកំណាត់សំពត់ស បើកាលណាធ្លាក់ចូលភក់ជ្រាំហើយ ទោះខំប្រឹងបោកគក់លាងសម្អាតយ៉ាងណា ក៏មិនដូចដើមដែរ» (courtesy of Frank Smith)

Let's put aside for the moment the blatant sexism in that proverb ("dropping them in the mud" is a metaphor for their being sexually active, and this is the classic embodiment of the double standard against women in so many traditional societies), and see if there is any useful imagery there for us to communicate a distinction in a totally different domain, without being insulting to more than half of the population.

The term "biopsychosocial massage" refers to massage practiced in an evidence-based, science-based, client-centered way, that understands health, wellness, and disease in terms of natural (not supernatural) processes in the material physical universe among biological, psychological, and sociocultural aspects of life, as well as their interactions and the emergent effects that arise from them.

Anyone who practices massage in this way is practicing BPSM.

If that term is consistently applied to only those practices, then it is a clean and brilliant diamond that clients and other massage stakeholders can use as a baseline to understand exactly what BPSM has to offer.

If the term is (figuratively) dropped in the mud by applying it to anything and everything, no matter whether or not it is consistent with the principles of BPSM, then--like the silk--it is stained forever, and it becomes useless for clients and other massage stakeholders to use as a guide to understand what BPSM has to offer.

So I give the terms "biopsychosocial massage" and "BPSM" to the community to use freely, on the one condition that they not be diluted by applying them as mere buzzwords to massage or other practices that are not massage practiced in an evidence-based, science-based, client-centered way, that understands health, wellness, and disease in terms of natural (not supernatural) processes in the material physical universe among biological, psychological, and sociocultural aspects of life, as well as their interactions and the emergent effects that arise from them.

(Not yet clear on what that means in actual practice? That's ok; there's a great deal of rich material there to explore in depth. We're going to spend some quality time connecting the dots, and translating them into what they mean for actual practice. I just want to get that general principle out there; now that it is, we can do some real work on establishing what it means in practice.)

So the answer to the question in the post title, "Who owns BPSM?" is: It is entrusted to the responsible and sustainable stewardship of the massage community.

 

cheers, to Diane Jacobs!

 


UPDATE, 18 November 2012, 10:57 AM PT:

Gayla Coughlin points out that some of my statements above, as written, are unclear in what they mean for actual practice, and might result in outcomes that I don't want.

I thank her for giving me the opportunity to correct my inaccuracies, and to get closer to my intended outcome.

I am thus taking out a Creative Commons license on biopsychosocial massage (BPSM), and here are the conditions attached to that license.

The particular form of the Creative Commons license that most suits my intent for this work is Attribution-ShareAlike CC BY-SA.

Their blurb explains:

This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is often compared to “copyleft” free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.

--"About the Licenses", http://creativecommons.org/licenses/ accessed 18 November 2012

 

What this means is that you can build on, develop, and grow biopsychosocial massage, but only on the condition that you share your work with the community in the same way ("license their new creations under the identical terms")--you cannot take the work that I and others have done on biopsychosocial massage, and trademark or copyright it for yourself. This license thus protects biopsychosocial massage for use by the entire community, rather than having someone seize it away from us in a proprietary way.

The Creative Commons Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0) page explains it in this way:

You are free:

  • to Remix — to adapt the work
  • to make commercial use of the work

This means it is approved for Free Cultural Works

  • Attribution You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work).

  • Share Alike — If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one.

With the understanding that:

  • Waiver — Any of the above conditions can be waived if you get permission from the copyright holder.
  • Public Domain — Where the work or any of its elements is in the public domain under applicable law, that status is in no way affected by the license.
  • Other Rights — In no way are any of the following rights affected by the license:

    • The author's moral rights;
    • Rights other persons may have either in the work itself or in how the work is used, such as publicity or privacy rights.

If my statements above sounded like I objected to commercial use on anyone's part, then that was due to my inaccuracy--I have no objection to anyone earning a living by teaching classes, writing books, or anything like that, as long as you honor the moral rights that attach to my Creative Commons licensing of biopsychosocial massage. And by "mere buzzwords", I was not objecting to using the term to market your works based on biopsychosocial massage. I specifically meant slapping the label on practices where it does not apply, in order to market something that is incompatible at its core with biopsychosocial massage.

By "moral rights", I specifically mean that I do not want anyone to use the label "biopsychosocial massage" to endorse practices that are anti-scientific or pseudoscientific, or that are not client-centered. Those violate the spirit of biopsychosocial massage, and are an infringement of my moral right to delineate a set of massage practices and theory that are consistent and compatible with modern science and with evidence in the material physical world.

If you respect that moral right, then you are free to build on and develop biopsychosocial massage for non-commercial or commercial uses, but you cannot take it away from the community by trademarking or copyrighting it for yourself.

So I believe that the conditions of this license protect my intent to release it to the responsible and sustainable stewardship of the community, at the same time that it protects the content from being distorted by misuse of the label to apply to something that contradicts the heart of biopsychosocial massage.

 

cheers, to Gayla Coughlin!

Biopsychosocial massage (BPSM): A new lineage

There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.

--Charles Darwin, Origin of Species, close of first edition, 1859

Charles Darwin, whose biological observations led to the development of evolutionary theory, and his wife Emma loved each other very much.

Their many letters to each other over the years (preserved online in the Darwin Correspondence Project) stand as a testament to how much they thought, cared, and worried about each other.

In one letter, written around February 1839, Emma expresses her wish as a faithful believer, but at the same time, also admits to her doubts in her own hope:

The state of mind that I wish to preserve with respect to you, is to feel that while you are acting conscientiously & sincerely wishing, & trying to learn the truth, you cannot be wrong; but there are some reasons that force themselves upon me & prevent my being always able to give myself this comfort.

--Darwin Correspondence Project, Darwin, Emma to Darwin, Charles [c. Feb 1839] accessed 17 November 2012

 

She wants to feel secure that, if she (or he, or anyone) is really trying diligently and sincerely to learn what is true, that that effort guarantees that she cannot possibly be mistaken about what she is learning. The reason she is so concerned about this is that she was devoutly religious, and she knew that Charles had doubts about religion.

To be impossible to be wrong, through sheer effort and sincerity, is a lovely wish--and yet, in the same sentence, she admits to her beloved husband that even she herself cannot always keep up that belief.

She was right to be concerned about that issue--the history of science at that time in England contains many examples of geologists, paleontologists, biologists, and other scientists who set out on a journey to find evidence in the material physical natural world that proved the stories in the Bible to be literally true.

For example, if the story of Noah's Ark and the Flood were literally true, you would find evidence of it in the layers of rock in that part of the world. The scientists who set out to find it discovered that that evidence is not there, but other evidence, showing that other things happened, is indeed there.

The scientists who set out to demonstrate that the earth is literally only a bit more than 6000 years old demonstrated instead that they would have to reject all the other multiple sources of repeatable, verifiable evidence that showed the earth to be much older than that.

Darwin himself demonstrated that--rather than the Genesis creation story that species were created one time in their present and unchanging form--species actually change over time to better adapt to the environments they find themselves in.

When the evidence these scientists found contradicted what they wanted it to say about the literal truth of the Bible, they faced a test of their own moral character in deciding what to do next about that fact:

  1. They could ignore the evidence, pretend the discovery never happened, and never face the meanings of the contradictions between the evidence and what they believed, or

  2. They could double-down on their belief, holding on even tighter to it while rejecting the reality of the material physical evidence, or

  3. They could accept the reality of the material physical evidence, revising their beliefs as needed to resolve the contradictions between the beliefs and the evidence.

Some of the most solid scientific knowledge that we rely on every day came from people who had the courage to face the implications for their beliefs that the evidence presented them, and the integrity to not turn away from or deny the contradictions, but rather to engage with them.

To take a more contemporary example of that same spirit, this quotation from Julie Onofrio is, for me, the essence of the courageous engagement that we so urgently need to participate in if we really want to become a profession:

Having an open forum and getting some help in analyzing research is really needed in our profession. Yes, I have to say it disturbs me when the researchers say things like traditional modalities don't work--it's like a slap in the face to all who are doing energy work, or reiki, or Rolfing, and having results and success. It's very hard not to take it personally, but also to set emotions aside and remain in communication. But that is why I support it. I want to learn more and to support the profession in understanding research.

 

This willingness to remain engaged, even when it's difficult because it contradicts what we've been taught, is nothing short of admirable. Julie is showing the courage of facing difficult dilemmas that evidence presents us about how massage actually works, and she is actively engaging with that process, and in that, she is going the extra mile.

Like Emma and Charles Darwin, most MTs are good, decent, caring, and loving people, who want to understand the truth.

If just wanting it sincerely, and working hard at it, were enough by themselves to avoid error, most of us would be there already.

Sadly, in this material physical universe, those good intentions are not sufficient to help us to be correct.

 

 


The National Certification Board for Therapeutic Massage and Bodywork (NCBTMB) is an independent non-profit organization that offers national certification in massage and bodywork.

This national certification functions as a path to initial licensure (sometimes the only path) for MTs in some states.

The Board has undertaken a major revamp of policies and procedures, one which is causing a great deal of disruption among nationally certified MTs and continuing education providers.

Its CEO, Mike Williams, states that the purpose and effects of this change are

streamlined online processes, enhanced communications, and improved programs that elevate the profession and better serve the public.

--NCBTMB front page accessed 17 November 2012

 

Some of those changes may well have that effect--I am not personally nationally certified, and I have not yet examined the changes in depth as other MTs and bloggers such as Laura Allen have.

But in the FAQ about the new procedures for approving continuing education providers, there is--for me--an absolute deal-killer.

 

Q: Will NCBTMB continue to accept alternative courses like energy work, aromatherapy, animal massage, etc?

A: Yes. Massage therapy is part of the holistic profession as are several other modalities and techniques. NCB will continue to accept modalities and techniques that can be legally practiced by a massage therapist without another healthcare provider, (i.e., DC, MD, PT) present. As long as the technique or modality can be shown to be embedded in the lineage of massage, it will be accepted. This means that if the core information of the technique or modality can be referenced as a derivative of another technique or modality that is within the massage therapy scope of practice it will be accepted.

--NCBTMB Approved Providers FAQ accessed 17 November 2012

 

 

The argument over the relationship between massage and "energy work" is nothing new.

In the early 1990s, when I was in massage school, the NCBTMB was developing the first national certification exam--the National Certification Examination for Therapeutic Massage and Bodywork (NCETMB). Eventually, as a result of consumer pressure, they were forced to offer an energy-free alternative, the National Certification Examination for Therapeutic Massage and Bodywork (NCETM), for those MTs who did not want to be coerced into an anti-evidential belief system as the price of their professional training and licensure.

Although the argument is nothing new, there was a fresh opportunity to do something innovative here among the other disruptive changes--but NCBTMB did not take that opportunity.

Instead, they opted to permit teaching any information (which includes misinformation and malinformation) as approved continuing education, as long that that can be shown to be "embedded in the lineage of massage". Considering the long history of "massage myths", documented by Laura Allen (here and here), Lee Kalpin, Paul Ingraham, and many others, it is clear that just because an idea has been embedded in massage, even for a very long time, that does not mean the idea is correct.

NCBTMB had an opportunity to stand up for the principle that, in the therapeutic encounter, a professional should provide only validated warranted (justified or justifiable) high-quality information to the client.

They did not take the opportunity to stand up for that principle, and as a result of that decision, I cannot participate in their new process. I will not go on to apply for national certification as a practitioner, nor will I become an approved continuing education provider under those standards.

I regret those facts, as I consider them massive missed opportunities. But I cannot do it, because our first principles on these matters are so far apart as to be irreconcilable.

Don't misunderstand me here--I am positive that the NCBTMB members are well-intentioned, and that they wanted to do the right thing. I genuinely believe that they were attempting to have the best of both worlds for the benefit of all massage stakeholders, and to not hurt anyone's feelings.

I respect them as the kind, caring, motivated, passionate people that they clearly are.

If that, by itself, were enough to be right, as Emma Darwin wished, we would not have to have this very serious and difficult discussion.

But evidence doesn't work like that--you can't pick and choose which evidence you accept, and which you reject. Either you accept all the evidence, and you go courageously wherever those implications take you, or you just don't accept the evidence.

If they are going to accept massage's traditional explanation of "energy work"--no matter how many times that explanation has been shown by the evidence to be mythical--as validated approved continuing education with their official imprimatur, then they are not preparing MTs who are taught that explanation for modern translational science. Holding on to old ideas even after they have been disproven is an active obstacle to understanding these new developments.

The environment of massage is exhibiting selection pressures toward a type of massage that is integrated with validated high-quality information, and that prepares MTs for understanding advances in neuroscience, cognitive science, endocrinology, and pain science, and translating that understanding into clinical practices that are client-centered and effective.

As a direct response of those pressures, biopsychosocial massage is breaking off from the main lineage of massage to provide a new massage lineage that is fully consistent with those principles.

You can consider this the official birth announcement of a new lineage of massage.

Biopsychosocial massage (BPSM) is massage understood and practiced in a biopsychosocial model. It understands massage, health, wellness, and illness, and the knowledge bases underpinning those concepts in an evidence-based, natural (meaning, not supernatural), organic way that draws on what we know about biology and other natural sciences, psychology, sociocultural aspects of being human, and the emergent effects that arise from interactions among these various factors.

Psychosocial and cognitive approaches don't require that you become a clinical psychologist but that you have a broad concept of the influence of those factors and that you account for them in your encounters with your patients. Know the literature and be able to give management advice based on evidence. When people come to see you they want a plan. Have a plan that is defensible and that works toward their goals. Address concerns, fear avoidance, other stress, and unhelpful beliefs with compassion, understanding, empathy, and informed knowledge.

Understanding why people hurt is part of our professional responsibility and should change most everything we do on a daily basis away from traditional methods and towards methods defensible with modern science.--Jason Silvernail accessed 5 August 2011

 

An example of a biological factor in health could be increased cortisol in the bloodstream in response to chronic stress. The interaction of that biological factor with the increased daily stress in modern society would be an example of interactions among biological factors and sociocultural factors.

An example of a psychological factor in health could be a man who is less likely to seek professional treatment for pain than a woman is, because of his perception that stoically enduring pain is what men do in the society he grew up and lives in. The increased structural damage that can occur as a result of ignoring symptoms and delaying treatment is an example of the interactions among psychological factors and biological factors.

An example of a social factor in health could be the relative stigmatization of mental or behavioral illness, as compared to how more clearly structural conditions are regarded. This stigmatization can drive psychological conditions underground--say, for example, if someone did not get needed psychological treatment because they didn't want it to show up in their medical record. That would be an example of interactions among sociocultural factors and psychological factors.

Biopsychosocial massage is client-centered. That means that the psychological and social factors in the client's unique experience, as well as the universal biological factors we are all subject to, is the center of where we focus our attention and caring. It doesn't mean that we accept everything in someone else's experience is literally true. It does mean that we recognize that, for them it feels true, and for that reason alone, it is important in where we meet the client in the therapeutic encounter.

Biopsychosocial massage welcomes self-expression and the art of massage. It is clear, however, that sometimes our need for self-expression can come into conflict with clients' immediate healthcare needs, and--when that happens--we recognize that, in order to act as healthcare professionals, our ethical fiduciary duty is to put the clients' needs first, ahead of ours if necessary.

Biopsychosocial massage is wholistic, integrative, and evidence-based. That means that it does not draw upon supernatural explanations of mechanisms, and it builds upon foundational knowledge in the sciences to evaluate and validate the evidence for or against particular claims of effectiveness or mechanisms.

That means that we understand and practice it in a holistic, complementary, and integrative way, integrated with other domains of human knowledge and with the natural universe we find ourselves in, rather than silo'ed off in an alternative universe that denies material physical reality, and isolates us away from members of the client-centered biomedical healthcare team.

If a proposed explanation for an effect requires us, for example, to reject physics, as the explanation of "energy work" embedded in massage tradition does, then we face that contradiction head on, and we work to resolve it. If that means updating old beliefs in the light of new evidence, then that is the consequence of practicing biopsychosocial massage.

Michael Hamm is another contemporary example of courageous engagement, facing the evidence head-on and seeking to better understand. I'm paraphrasing his quote here, and I trust that he'll correct me if I've gotten it wrong. If I can find the original quote, I'll replace the paraphrase, but it was something to this effect:

I understand and accept that the traditional anatomical explanation behind craniosacral therapy doesn't hold up in light of the evidence. At the same time, I can't deny that I feel something when I am doing that work, something that I can't explain. I want to better understand what is going on when I do that work.

 

In the absence of clear evidence of what is exactly going on, this suspension of previous belief that has been disproven (and not yet replaced) is totally in line with the principles of BPSM. We don't have to always know everything; we just have to know what we do know, what we don't know, and how strong the evidence is behind our knowledge.

Since our encounters with clients will always run ahead of the available high-quality evidence, we don't limit ourselves only to what has been rigorously validated by studies and nothing else. We take our professional experience into account, and we actively seek to understand and incorporate the clients' preferences, whenever possible, in treatment. But in all these cases, in developing our approach to caring for the client, we remain clear on what is evidence, what is speculation, what is science, what is art, what is literal, and what is metaphor.

Understanding the material physical universe around us, and the centuries of cumulative human knowledge about that universe, give us powerful tools to draw upon. That understanding, combined with the caring that characterizes so many people who choose to go into massage as a career, is the heart of biopsychosocial massage.

Neil deGrasse Tyson sums it up almost perfectly:

I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You'd be surprised how far that gets you.

--Neil deGrasse Tyson

 

That quotation demonstrates the core of massage in a biopsychosocial model.

Over time, here at POEM, we will be following that evidence where it leads, and courageously engaging with the meanings that it shows for the practice of massage therapy. I expect intense, passionate, and fruitful discussions here over the next few years.

If your client, your friend, your relative, or you may be experiencing domestic violence

 


Why you may want to know this

While the statistics on domestic violence vary widely, we know at the very least that it is a large and underreported worldwide problem. It doesn't respect class, income, religion, or any other number of demographic factors; it cuts across all of them and is represented in every population group. While women are most often the victims of male abusers, it is also true that there are female abusers as well as male victims. The gay and lesbian community is also not immune from the problem, so probably one of the most important things we can do is not to bring assumptions into the therapeutic encounter that create the impression that we cannot be confided in if our client needs to reach out for help.

Depending on the licensing jurisdiction (state, province, other region) you live in, as an MT, you may or may not be considered a healthcare provider, and you may or may not be a mandated reporter, which means you have to report cases of abuse, or your suspicions that abuse may be taking place. Patient confidentiality and privacy is always important, and even required, but there are times when for the safety of yourself or another, patient confidentiality may have to be broken in order to fulfill the mandated reporter requirement. I really can't give you a one-size-fits-all answer here, except to say that you should be aware of the laws that apply to you, and what your responsibilities for protecting your clients under those laws are.

Not everyone encounters domestic violence, but many of us will have a client, a friend, or a relative who faces it. Some of us may experience it ourselves. We may never need this information, but if we ever do need it, it is better to have it in advance, rather than try in the middle of an emergency to find it from scratch.

In general, massage schools don't prepare us for what to do if, in the clinic, a client tells us they are being abused, or if we suspect that a client is being abused.

This general information from GroupHealth (such as definitions, the description of the battering cycle, the effects on children, and making a safety plan) is relevant for anyone, while the specific information (such as telephone numbers) is relevant for people, primarily GroupHealth Cooperative members, in the Seattle area.

What you may want to do with this information:

  • Find out what your legal responsibilities are where you live and where you have your license. Specifically, find out whether you are considered a healthcare provider, and whether you are considered a mandated reporter. If so, for what populations are you a mandated reporter? Everyone, children, elderly clients?
  • Take the following information provided, and replace the phone numbers and websites with information that is relevant and helpful where you live--local resources, for example.
  • Visualize scenarios with clients where you may need to provide information about where to turn for help, as rehearsal in case this situation ever occurs in real life. You may wish to adapt this information for a brochure that you keep in your office, and can give to clients who need it. You can find brochures online, or you can adapt the following information.
  • Be clear on our limits and scope of practice--we are not psychotherapists, and we do not counsel. But we can have general educational material, such as is contained in this brochure, available for distribution, and we can refer out when we are confronted with a situation that is outside our scope of practice. And counseling domestic violence victims is definitely outside our scope of practice.
  • Reach out for help, preferably before you need it--cultivating a network of therapists and counselors to whom you can refer clients, if you ever need to, is always a useful step. And you may find you want to check in with a counselor or mentor as well, if a particularly harrowing story from a client has a strong bad effect on you (secondary trauma) as well.
  • Be prepared. If someone else in your life, other than a client, ever confides in you that they are in a domestic violence situation, you can be a supportive friend to them as well, and urge them to get professional help. And if you ever find yourself in a domestic violence situation, please don't hesitate to reach out. There are caring people out there who want to help. No one ever deserves to be abused. You deserve to be safe.

When I picked up the flyer at their medical center, I inquired about disseminating the information, and was told that they care more about getting the information out to people who need it than strictly about the copyright, so it would be ok to reproduce it here.

What is domestic violence?

Domestic violence is violence or the threat of violence in an intimate relationship. This is often referred to as intimate partner violence or IPV An intimate relationship includes couples who are married, living together, or dating.

Domestic violence is sometimes called "battering" or "wife beating": it's always abusive. An abuser is a person who uses or threatens the use of violence to control another person. A victim is a person to whom a violent act is directed.

Many abusers grew up seeing violence as the way to express anger or as the method used to get control. Because of this, violence is what he or she uses as an adult to express anger or gain control.

Domestic violence is never okay--no one ever deserves to be abused. It is never the fault of the victim.

Who is abused?

Domestic violence happens to people from all different kinds of backgrounds. It happens to people of all ages, races, cultures, sexual orientations, religions, economic levels, and educational levels. Both men and women can be victims of domestic violence.

What is abuse?

Abuse falls into three categories: psychological, physical, and sexual. An abuser may use any or all types to try to control the victim.

Psychological Abuse

Psychological abuse may include name-calling or teasing, controlling the victim's activities and relationships (hobbies, friends, etc.), controlling the victim's appearance (clothing, hair style, etc.), not allowing different opinions, threatening harm or violence, or threatening suicide if the victim doesn't cooperate with demands.

Physical Abuse

Physical abuse can include punching, pushing, biting, slapping, pulling hair, kicking, pinning down, or choking.

Sexual Abuse

Sexual abuse can include any unwanted touching or fondling, physically attacking breasts or genitals, any unwanted sexual contact, including oral, anal, or vaginal intercourse, or the use of force during sex.

Why don't victims leave?

Many victims feel they have no control over the violence because it happens no matter what they do. Victims may be isolated from others, often because of the abuser. If they do have contact with people, they often don't talk about the violence due to feelings of shame and fear.

A victim may feel he or she is the only one being abused and no one else would understand. Or, the victim may believe all relationships are violent and so the abuse is normal and acceptable.

A victim may stay with the abuser for many reasons:

Fear
  • Lack of physical protection.
  • Fear of retaliation against victim or family.
  • Fear of losing custody of children.
  • Losing financial support.
  • Fear of losing one's job.
  • Having nowhere to live.
  • Being alone.
Social and cultural reasons
  • Family tells victim to stay.
  • Family sees it as a private issue.
  • Abuse may be viewed as acceptable in some cultures.
  • Family tells victim to make the best of it.
  • Others won't believe the abuse happens.
  • Religious beliefs (that it is wrong to break up a marriage.)
  • Cultural beliefs (that it is wrong to get help.)
Beliefs of victim
  • Feels helpless to change the situation.
  • Believes things will get better.
  • Feels deserving of the abuse.
  • Feels sorry for the abuser.
What is the battering cycle?

There are usually three phases to domestic violence, called the battering cycle. The cycle continues until the abuser or victim gets out.

Phase 1

Tension builds up. There is an increase in criticism and insults.

Phase 2

Abuser explodes into violence for little or no apparent reason.

Phase 3

Abuser apologizes and says it will never happen again, or acts as if the violence never happened. The abuser is often very charming and attentive to the victim during this phase, and promises to change or attend counseling.

How are children affected by domestic violence?

Children are impacted by domestic violence, either by witnessing the abuse or by being abused themselves. Children who witness abuse may learn that violence is normal, and is an appropriate way to solve problems.

Children affected by domestic violence may show any of the following traits:

  • Anxiety and fear.
  • Shame.
  • Depression.
  • Guilt, because they feel the violence is their fault or because they can't stop it.
  • Confusion about the love and anger they feel for the abuser.
  • Afraid of being left by one or both parents.

 


Children may experience physical problems resulting from emotional stress, including:

  • headaches
  • bedwetting
  • rashes
  • hearing or speech problems
  • sleeping or eating disorders
  • learning problems

 

They may also develop behavioral problems at school or at home or act withdrawn.

 


Develop a safety plan

If your partner is abusive, it's important to develop a safety plan for you and your children in case the violence happens again.

Make copies of important papers including:

  • social security cards
  • birth certificates
  • restraining orders
  • bank account statements
  • insurance policies
  • your marriage license, if you have one

 

Hide them with a close friend or relative.

Hide extra clothing, money, ATM and credit cards, and an extra set of keys with a close friend or relative.

Open a checking account separate from the abuser.

Remove weapons from your home.

Set up signals with neighbors, friends, and relatives that will let them know you are in danger. A signal could be a code word to use on the phone to indicate trouble, or closing a curtain in a certain window. Ask a neighbor to call police if violence begins.

Identify a safe place to go, and practice how you will get there. Make plans to take your children with you. Prepare older children to leave and call police from a neighbor's house if you can't get away.

During an incident:

Call 911 for help.

Get out if possible. If you must leave without your children, come back with the police to get them.

If you can't leave the situation:

Avoid rooms with only one exit.

Avoid the kitchen, bathroom, bedroom, and garage.

 


Computer safety

If the abuser can access your computer, they can find out what Web sites you have visited, what documents you have written, even what e-mail you have sent. The safest thing to do is to use a computer at the library instead of your computer at home.

Commitment in the therapeutic encounter: You can have anything you want, but you can't have everything you want

It's a lovely idea to think that there are no limits, and that we can have everything we want.

Certainly, a massive part of the US advertising industry is dedicated to selling that dream, precisely because it's such an appealing one. There is no shortage of people who will pay good money for the hope of living without limits.

In the realm of dreams and ideas, there may well be practically no limits to what we can imagine. But the material physical world imposes constraints, or limits, on what matter and energy are capable of, and what they cannot do.

We don't understand everything about why matter and energy behave the way they do, but over the centuries, we've observed them in enough different situations that we're pretty good at describing how they behave in those situations. It's very much like the situation with gravity--there are several different and mutually exclusive proposals for what gravity is, and why it works the way it does.

But we don't need to wait until those questions are decided to be able to predict how gravity will behave well enough for hundreds of thousands of airplanes worldwide to take off and land safely (for the most part) every day. We can predict its behavior so accurately that in 1970, when the Apollo 13 spacecraft suffered an explosion and fire on the way to the moon--an explosion which left the spacecraft badly damaged, and low on fuel to get back to earth, and oxygen for the astronauts to breathe--ground control was able, on the fly, to improvise a plan that took advantage of the Moon's gravitational field to act as a "gravity slingshot" to propel the spacecraft and all 3 astronauts safely back home.

The same is true for matter and energy. These behaviors are so reliable that their descriptions are called "laws of physics"--metaphorically, it's as if they "know" they have to "obey" certain "laws", so they always do so.

Of course, science never says anything is definitively, 100% certain. Some things are very uncertain, and they're likely to be revised as we learn more about them.

Other things, while not 100% certain, can be almost 99.9999% certain--so the effect is as though it's perfectly certain, even though there's always that tiny 0.0001% chance it will be changed someday in light of new evidence, if that new evidence ever does show up on the scene.

The limits of the material physical world around us have been observed, described, and discussed for thousands of years, and, because they are so reliable, you can see, many times, the same description of the consequences of those laws of physics being discovered independently in different cultures far away from each other in time and space as ancient Greece and medieval India.

One of those consequences, borne out time and time again by the behavior of matter and energy, has been described as the "principle of non-contradiction"--that, in the material physical universe, something cannot both exist and not-exist at the same time, or that something cannot be both true and false at the same time.

Did that statement make you think of Schrödinger's Cat? If so, then that's an excellent question you raise!

At first glance, it seems as though the cat might provide an exception to that rule: the cat is both dead and alive at the same time in this thought experiment.

Yet it doesn't really, and here's why.

Source: http://upload.wikimedia.org/wikipedia/commons/9/91/Schrodingers_cat.svg accessed 7 October 2012

 

It is typical of these cases that an indeterminacy originally restricted to the atomic domain becomes transformed into macroscopic indeterminacy, which can then be resolved by direct observation. That prevents us from so naively accepting as valid a "blurred model" for representing reality. In itself, it would not embody anything unclear or contradictory. There is a difference between a shaky or out-of-focus photograph and a snapshot of clouds and fog banks.--Wikipedia, "Schrödinger's cat" accessed 7 October 2012

—Erwin Schrödinger, Die gegenwärtige Situation in der Quantenmechanik (The present situation in quantum mechanics), Naturwissenschaften
(translated by John D. Trimmer in Proceedings of the American Philosophical Society)
 

 

When we're talking about the cat being simultaneously dead and alive, we are talking about a phenomenon at only the subatomic level of organization--what Schrödinger called "an indeterminacy originally restricted to the atomic domain".

When we're engaging with clients in a therapeutic encounter, however, we are not engaging solely on a subatomic level--we're engaging at many levels, up to and including the organism level: Schrödinger's "macroscopic" level.

To confuse the subatomic level of organization with the organism level is to make the same mistake as to assume that--because both sodium and chloride as elements are immediately and painfully deadly to humans at the atomic level, then their compound--salt--also shares those properties. (Although it is true that too much salt over too many years can wreck your health, but only in a very different way from elemental sodium and elemental chlorine.)

To confuse those levels of organization with each other is to "naively accept...as valid a 'blurred model' for representing reality". At the subatomic level, without an observer, we can use words or images like the previous one to imagine a cat that is simultaneously dead and alive.

In our macroscopic material physical reality, the moment an observer looks at the cat to see what is going on, the subatomic waveform collapses--it definitively commits to one state or the other, but not to both at the same time--and we have either a dead cat, or a live cat, but never both simultaneously.

Unlike the poor cat (sometimes), the law of non-contradiction is still alive and well at the organismal level of material physical reality, where our therapeutic encounters with our clients take place.

Our metaphorical "waveforms" also are forced to collapse in one direction ot the other at this point, but--unlike the electron--at least we get to choose which of the two mutually-exclusive options we commit ourselves to.

This principle shines a spotlight on where a number of the most heated battles in massage's culture wars are currently taking place.

We have to decide one way or the other on the following question--because of the law of non-contradiction, we can't just say "both", and hand-wave our way out of the profound philosophical and scientific questions it raises.

As a first principle, do we accept or reject the reality of the material physical universe?

 

We have the freedom to choose either answer, but--no matter how much we may want it--we can't have it both ways.

The answer we choose to that question will determine what we have to offer to clients, as well as how we relate to one another.

This, in turn, will set in motion what history will tell about how our future of massage turned out.

What Seth said

Seth Godin writes, on the natural human tendency to deny facts we don't like:

The problem with Orwellian talking heads, agitprop, faux news and Ballmer-like posturing is that they take away a foundation for a genuine movement to occur, because once we start denying facts, it's difficult to know when to stop.

 

Still, it's understandable--when reality seems overwhelming, the temptation to deny that reality, and avoid the pain of dealing with it, can be very strong. Barrett Dorko also has an excellent take on that phenomenon and this article, over at SomaSimple.

We've got a lot of massive problems in massage--for example, at the same time that we have the chance for a place at the healthcare professional table under Obamacare, and that we say we want to be taken seriously as professional members of the healthcare team, our major credentialing organizations grant recognition to courses that take money for teaching claims like "body cells carry emotional memory", "craniosacral therapy moves skull bones", and "all past traumas are stored in the fascia".

Anyone who had a decent education in anatomy should be able to debunk those claims after the first day of the first class.

Yet our major professional organizations visibly sanction the teaching of claims like these and grant CE credit for them, at the same time we say we want to be real healthcare professionals.

Our walk doesn't match our talk, and the problem's not going to go away just because we refuse to face it.

If we refuse to face it and discuss it in a civil and professional way in an attempt to reach solutions, history's going to make us eat the decisions that others make for us about these problems.

And if we claim we want to incorporate the latest neuroscience findings into massage as a healthcare profession, and we start that process off by being Neurophysiology 101 denialists, how, exactly, is that supposed to work?

No one's denying the fact that this shift to accepting facts and material physical reality is going to cause a great deal of disruption and moral distress. The world has entirely shifted out from under us, and the old social contract that we were comfortably used to just does not work any more.

That fact is going to cause an unforeseeable amount of pain and distress, and we need to be extra kind to each other as a result.

But denying reality is not a sustainable choice anymore, and the only real question is whether we'll make the change in time to make use of these new opportunities, or whether our process will make us too late to accept the invitation, and we'll totally miss out.

Godin provides an aspirational ideal to assist in that process:

Transformational leaders don't start by denying the world around them. Instead, they describe a future they'd like to create instead.

 

We can't change the larger universal material physical reality that confronts us. What we can change is how we react to it, and that reaction--what we commit to--will sow the seeds for the future we want to create.

Sometimes evidence shows that the old ways actually are the best

While cherry-picking--the act of suppressing evidence that doesn't support our own particular biases--is something to be avoided, berry-picking, on the other hand--carrying out our searches for information in a way that is not strictly linear and that incorporates cognitive questions, by allowing those searches to evolve and change in response to what we initially come across--is not only to be encouraged, but can be absolutely delightful in the unexpected directions it leads us.

This morning, berry-picking took me in a most unexpected direction. On the way to looking up something else, I came across this:

Risks of consuming fermented foods

Alaska has witnessed a steady increase of cases of botulism since 1985. It has more cases of botulism than any other state in the United States of America. This is caused by the traditional Eskimo practice of allowing animal products such as whole fish, fish heads, walrus, sea lion, and whale flippers, beaver tails, seal oil, birds, etc., to ferment for an extended period of time before being consumed. The risk is exacerbated when a plastic container is used for this purpose instead of the old-fashioned, traditional method, a grass-lined hole, as the botulinum bacteria thrive in the anaerobic conditions created by the air-tight enclosure in plastic.--Wikipedia, "Fermentation: Risks of consuming fermented foods accessed 3 October 2012

 


Slightly off-topic, but interesting (I think!), in a berry-picking way, since we care about calling people by the names they want to be called: Did you notice that the paragraph used the word "Eskimo", and did that perhaps seem a little strange to you, because you've heard that you shouldn't use the term "Eskimo" when you mean the Inuit people, since the word is derogatory or pejorative or insulting?

You're not wrong, if you remember hearing that--the word "Eskimo" probably does, historically, have connotations that are belitting and insulting, and Native American and First Nations people have spoken out explicitly and firmly against the use of the word.

At the same time, there is no good inclusive replacement term that includes the Yup'ik peoples of Alaska--if you just say "Inuit" instead of "Eskimo", that's fine if you mean only Inuit people and no one else.

But if you mean Inuit people together with Yup'ik people, then there really isn't a well-known acceptable term that means both. So often, you will see Alaskan Native American (more so) and Canadian and Greenlandic First Nations and Inuit people (less so, or maybe even not at all, per Lee Kalpin's comment following this post) compromising, and using the term in order to be inclusive, despite the connotations that go along with the word.

 


What's happening in Alaska?

Alaska has witnessed a steady increase of cases of botulism since 1985. It has more cases of botulism than any other state in the United States of America.--Wikipedia, "Fermentation: Risks of consuming fermented foods accessed 3 October 2012

 

Botulism is a condition that paralyzes people and animals who eat food contaminated with botulin toxin, or who have an open wound through which the bacteria that produce the toxin (Clostridium botulinum) can enter the body. C. botulinum is an obligate anaerobic bacterium, meaning that it is obliged to grow in an environment without air--oxygen is deadly to it.

VERY IMPORTANT WARNING

This is why you absolutely never, under any conditions at all, give honey to babies under 1 year old--they don't yet have the immunity to fight off the bacteria that produce the toxin.

After 1 year of age and older, people can fight off the actual C. botulinum bacteria themselves, so the bacteria can't gain a foothold in their systems to begin pumping out the toxin.

But if the neurotoxic poison produced by that bacteria has already contaminated the food somehow--as opposed to the bacteria themselves--then that toxin can produce botulism in anyone.

 

Facial paralysis which spreads through the body is a typical symptom of botulism; very bad cases can actually cause death by paralyzing the muscles needed to breathe.

The 14-year-old in these pictures from Wikipedia show the paralysis that's typical of severe botulism. Although he appears dead, he was actually fully conscious, yet unable to move. His eyelids were drooping and his eyes were paralyzed, and the pupils were fixed and dilated. We hope he made a full recovery--Wikipedia doesn't tell us how his story turned out--but even if he did, it would require a long, slow, difficult path to rehabilitation.

 

"A 14-year-old with botulism. Note the bilateral total ophthalmoplegia [paralyzed eyes] with ptosis [drooping eyelids] in the left image and the dilated, fixed pupils in the right image. This child was fully conscious."

From 1950 to 1997, 105 confirmed outbreaks of foodborne botulism involving 214 persons occurred in Alaska (there were no confirmed cases during 1947-1949)...All cases occurred in Alaska Natives. The average annual incidence among Alaska Natives increased from 3.5 cases/100,000 population during 1950-1954 to 10.7 cases/100,000 during 1995-1997 [in other words, right about 3 times as many cases as you'd expect, based on history].--State of Alaska Public Health Epidemiology Report: Botulism in Alaska--A Guide for Physicians and Health Care Providers, 1998 Update accessed 3 October 2012

The Rose Urban Rural Exchange, in its own words, "aims to strengthen relationships between urban and rural Alaskans by building mutual respect and understanding, and fostering a statewide sense of community through cross-cultural immersion.".

They have a website where they promote cross-cultural understanding by presenting pictures and reports of daily life, festivals, and other events.

In a post, "The Best of the Whale", one of their writers, Bogdan, presents pictures from Ilisagvik Inupiaq Culture Camp, where elders and others share a meal of traditional foods.

Notice the blue plastic container, and the Ziploc plastic bags--we're going to get back to those in a moment.

Bogdan describes the scene:

The most desirable food served at the blanket toss festival is fermented whale meat and blubber (mikiaq). Elders particularly like mikiaq, because it is easy to chew. To keep the audience interested and at the site, mikiaq is served last, after all the other food items have been distributed.

 

Mikiaq is

raw whale blubber that has been left to soak and ferment in the whale's blood.

 

Fermentation occurs when, under anaerobic conditions (reduced or no oxygen), you convert sugars (carbohydrates containing carbon [C], hydrogen [H], and oxygen [O] atoms as building blocks) like the kinds of glucose here:

into ethanol, the kind of alcohol in drinks such as beer, wine, and spirits, a process which rearranges those atoms into this arrangement:

Greenlandic to English Dictionary

nuna iterssaliorpâ: digs a hole in the ground, p. 180 (Old orthography)

qasaerdlâq: a seal which has been put by whole and left to ferment, p. 211 (Old orthography)

 

Back in the old days, fermenting the mikiaq was accomplished by digging a hole in the ground, and leaving it there for as long as it took the process to occur naturally.

Nowadays, just like most of the rest of us reading this, circumpolar peoples have access to modern conveniences like the blue container and the Ziploc bags you saw in the photo from the festival.

Plastic bags, containers, and utensils, no matter how bad they are for the environment, have some convenient qualities that make them so widespread in food preparation. One of those properties is the ability to keep food fresh for longer periods of time.

It does this by sealing the food away from exposure to air that would cause it to decay faster. In other words, it promotes an anaerobic environment.

And that's where the connection to the increased cases of botulism lies.

This is caused by the traditional Eskimo practice of allowing animal products such as whole fish, fish heads, walrus, sea lion, and whale flippers, beaver tails, seal oil, birds, etc., to ferment for an extended period of time before being consumed. The risk is exacerbated when a plastic container is used for this purpose instead of the old-fashioned, traditional method, a grass-lined hole, as the botulinum bacteria thrive in the anaerobic conditions created by the air-tight enclosure in plastic.--Wikipedia, "Fermentation: Risks of consuming fermented foods accessed 3 October 2012

 

Fermentation in a grass-lined hole, while still an anaerobic process, is less efficient at keeping the oxygen out, since air will circulate in and out of the hole and between the blades of grass. The C. botulinum bacteria have to overcome the deadly oxygen in that air, if they are going to establish a strong enough foothold to produce enough neurotoxin to make the mikiaq dangerous to the people who eat it.

A plastic container, on the other hand, does a much better job of keeping out the oxygen. Less oxygen in the container means a more welcoming environment for C. botulinum, where they can start to churn out neurotoxin.

As plastics have come into wider and wider use in the general population, and as they have made their way to more remote areas, where the convenience appealed to people, they took the existing risk of botulism, and--by providing a better anaerobic environment--sent the cases of botulism much higher than had been the case when mikiaq used to be fermented in the traditional grass-lined hole.

 


What all this means is that--contrary to what you may have heard--evidence-based practice does not mean that you have to give up traditional practices just because they are traditional, and adopt modern practices just because they are modern.

It means that instead of a top-down simplistic rule-based approach (either "Old = Good! New = Bad!": the "Argument from antiquity" fallacy, or the other way around, "Old = Bad! New = Good!": the "Argument from modernity" fallacy), we take a bottom-up approach of examining the evidence itself, and then deriving more nuanced and accurate rules that we can turn around and apply. Which, in turn, means that everything, traditional and modern alike, gets examined to find out:

  • what works in the way it claims to,
  • what doesn't work in the way it claims to, and
  • the mechanisms for why that is the case.

 

Once we better understand the answers to those questions, we can better decide which practices fit better into our client-centered model of service, and why they do so. This example was a perfect demonstration of how sometimes evidence supports the traditional practice as objectively better, as measured on the basis of outcomes (number of cases of botulism), than the modern practice.

What Seth said

Denying reality is not a sustainable choice anymore, and the only real question is whether we'll make the change in time to make use of these new opportunities, or whether our process will make us too late to accept the invitation, and we'll totally miss out.

Godin provides an aspirational ideal to assist in that process:

Transformational leaders don't start by denying the world around them. Instead, they describe a future they'd like to create instead.

 

We can't change the larger universal material physical reality that confronts us. What we can change is how we react to it, and that reaction--what we commit to--will sow the seeds for the future we want to create.

Part 1: Foundational concepts--anatomy, physiology, life, levels of organization, and regulation

 


What we are going to do in this course is this: for validated scientific anatomical knowledge, we are going to create and make openly available anatomical knowledge organization templates (KOTs), based on the original Anatomical Knowledge Organization Templates developed by my teacher, Cornelius Rosse.

 

 

KOT here

 

 

 

 

 

 

 

 

 

 

 

 

http://sig.biostr.washington.edu/education/resources/KOTorgan.html

 

sections of NCETMB and NCETM that we address here

 

 

Examples:

 

anatomy: gross, histology, microscopic, comparative ==> levels of analysis

 

physiology: how do the anatomical parts actually work, how do their structure and orientation and location influence what they can do, how body systems work together, and how they influence each other ==> regulation, emergent properties, systems science

 

can we always separate those questions? mouse prostate example

 

 

but most of the things we are dealing with will be much more straightforward than that. when it's harder, we'll flag it.

 

 

 

 

 

============================================

 

How do we study anatomy and physiology?

 

Anatomy is easier to visualize with our eyes, with dissections, and instruments like microscopes: "learning to see what we're trying to understand".

 

Physiology is processes: we need to know how to approach more complicated visualizations

 

what we can see and touch on dissections: gross anatomy (and you can imagine the jokes punning off of "gross")--formalin smell

 

histology: study of tissues, built up of cells (cytology)--uses microscope in order to understand how tissues can work (physiology), we have to understand structure of cells on microscopic level (anatomy)

 

neural tissue made up of neural cells can support memory because their structure can carry electric signal. other types of tissue cannot because they cannot carry electrical signal. so if you see claims that body cells carry emotional memory, you have to choose between that and histology. What we see inside the cell, how the cells are arranged in relationship to each other, how much space is between the cells--all of these material physical anatomical aspects of cells influence what physiological functions the tissues made up of those cells are able to carry out

 

microscopic anatomy: looking at cells and tissues under a microscope/histology

 

cytology

 

we are getting into levels of analysis here

 

two resources that we will draw upon here as necessary are embryology (developmental biology) and comparative anatomy--together, they are called evo-devo

 

you won't be tested on these subjects. but the knowledge they contain will support our reasoning about the anatomy that we *are* responsible for knowing, so we'll take them into account in order to more fully understand the subject.

 

comparative anatomy: why do humans have 1 prostate and mice have 5? why do bears have anucleate cells? the answers to these questions provide valuable information about human anatomy, in a (metaphorically) similar way to how learning a foreign  language can help us better understand why our native language does things in the way it does. this is one of the bases for comparative medicine: MIN

 

model organism examples: in-depth understanding

 

levels of analysis:

 

(smaller ones we haven't talked about yet)

cellular anatomy and histology

gross anatomy

(larger ones we haven't talked about yet)

 

notice that the levels of analysis are very different from each other. MIN

this will become important when we look at how people try to talk about massage and quantum physics. when we get to that, it will be your job to decide whether what they say makes sense. To do that, you need to be aware of what it means to talk about different levels of analysis, and how structures and functions of the same thing at one level of analysis can be very different from structures and functions of that same thing at a different level of analysis

 

 

look at one level of analysis, and understand how it leads to supporting structure and function at the next level of analysis

 

"system by system and connect the dots"

 

anatomy: how do we use our "eyes, microscope, and imagination" to develop a good, solid, and in-depth understanding of anatomy and physiology that will support us in providing high-quality, client-centered care?

 

 

physiology: how do we use our "anatomy knowledge, logical thinking, and basic knowledge of chemistry and cell biology" to develop a good, solid, and in-depth understanding of anatomy and physiology that will support us in providing high-quality, client-centered care?

 

"anatomy is very visual"

 

you can't understand how body parts and systems work (physiology) if you don't understand the anatomy where physiology happens (and, later, pathology--abnormal functioning)

 

 

logical thinking: "a lot of physiology is connecting dots, step-by-step" -- how these parts work together

 

 

basic chemistry and cell biology that you need to understand to make physiology make sense: plausibility

 

 

"Complementary principles

 

Function cannot occur without structure

 

Functions are often dictated by form" MIN

 

you need physiology to stay alive. dead bodies can have anatomy.

 

"interconnected: you need both to stay alive, and you need a good knowledge of both to be successful" this is a bridge or an obstacle to integration

 

 

"What is life"

Always an interesting question to ponder

Schrödinger's paradox--order comes from disorder

Socrates--objects are a reminisce of previous objects

Hooke & Schwann cell theory (more later)"

 

 

when we say we practice massage because we want to make a difference in people's lives, what is the implicit knowledge that we are drawing upon to ground what we say

 

 

many viewpoints on this: philosophical, Socrates, "The Republic", the Cave--we're shadows of former objects

 

science: order comes from disorder==?chemical reactions, cells, movements of molecules and ions into and out of cells--"there needs to be some kind of chaos on the molecular level for us to stay alive"

 

chaos: sperm in water, hormones rather than vasculature in fish

 

 

cell theory (what is a theory), then modern cell theory==life cannot occur

without cell, cell is functional unit that drives life--this is why viruses are not considered alive to understand what it means to be alive, we need to understand levels of organization--at what level does life actually begin?

 

we have to talk about matter--matter is anything that takes up space and has mass--some kind of physical presence

 

atoms--smallest simplest forms of matter in nature, can't see, have various behaviors--examples C, H, O,N, K+, various behaviors

 

molecules/compounds--combinations of atoms; glucose, protein, lipid, hormone, chemical message, structural protein like cell membrane--is a protein or a sugar alive? they don't have a metabolism

 

organelles--look at a cell, as we will next week, see distinct parts, nucleus, ER, Golgi apparatus, ribosome: sacs with enzymes that drive biochemical reactions--can a fuel factory be alive? no, separate and not organized

 

cells--organized organelles, start to see life take place--nucleus, DNA inside can start to use all other organelles for chemical reactions--this is where life begins, at cellular level--political implications, pro-life,

pro-choice

 

tissues--put cells of different varieties into organized tissues

 

organs--organized tissues of different types

 

organ systems--11

 

organism

 

population systems--how long can you go without any human contact? how well

could you survive on your own? we need each other to survive. everyone is

different in levels of need, but we need each other

 

fractal: population system, analogies with organ systems and with cells

 

image of levels of organization

 

where does life begin? at cellular level

 

"Interrelationships of organ systems

cells rely on organ systems to maintain life

cells drive the function of organ systems

the interrelationship of these two concepts drive life"

 

MIN

 

we have to go all way down to cellular level for good understanding of

physiology

 

good part of physiology n day 2 day level is keeping cells alive: example

respiration

 

bridge to pathophysiology

 

what are the pathological changes that occur at the cellular level--what drives disease to happen? what cellular changes occur that make the tissue go awry?

 

cells drive live; most of our physiology is spent keeping life going at the cellular level

 

"Requirements for life

 

boundaries

movement

responsiveness

digestion

metabolism

excretion

reproduction

growth and change

 

what organ systems drive each of these functions?"

 

 

physical boundaries; borders between tissues, organs, cells, internal ve

external--skin is major outer boundary, connective tissue serve as boundaries inside

 

why do we need movement? get meal, look at animals who don't get blood clots in hibernation—musculoskeletal responsiveness to changes--changes in environment (int or ext) occur all the time--we need to be able to adapt to them, and if we can't, we will die--

nervous, endocrine--homeostasis later

 

digestion--breaking food down into simplest building blocks so that we can absorb it and make use of it--1, eat the food 2, break it down 3, absorb it 4, excrete it what don't absorb when finished--if you understand these concepts, then you can understand diseases like Crohn's disease or diarrhea

 

metabolism--what is metabolism? burning calories? digesting food? only 1/2 the equation--metabolism is about all chemical reactions that occur in body--certain systems help regulate, nervous, endocrine--life-giving chemical reactions occur within cell itself--building up and breaking down molecules in the chemical reactions that sustain life

 

excretion--where there is metabolism, there has to be excretion, because there are waste products left over--CO2, for example. respiratory system--urinary system, kidneys, waste filtering organs--without kidneys, won't live very long--skin can sweat out some waste, digestion--kidneys biggest one,

cells constantly excreting waste products (lymph)--constantly producing waste products, must be removed--remove organic waste products

 

reproduction--permits continuity of life--extremely important organ system--we are reproducing faster than we are dying off--panda bears--poaching is a problem--big mammals in general take a long time to reach sexual maturity, so vulnerable to poaching--when are we readily physically to reproduce--puberty--8-13 years after we're born. physiologically, not

psychologically. we as a species not threatened enough to get us to point where repro is big issue for us.

 

growth and evolution--growth necessary for life to take place. compare birth. grow to self-sustainable, mature organism. evolution as well--evolution is just change--adapting to environments and surviving--we need to evolve to changes in environment as well--and animal or plant that does not evolve will not survive--

 

"survival needs

 

oxygen

nutrition

water

normal temperature

pressure"

 

oxygen big part of making ATP and cellular energy--big metabolic deal

 

nutrition--calories, fuel, making energy, protein to make plasma proteins, need structure--protein deficient people look very wasted away because digesting own muscles--vitamins, minerals, proteins  fats for energy storage, structural purposes, driving metabolic reactions

 

water main transport medium, bulk of body is water--most people have ~40 liters of water in blood and tissues, helps drive chemical reactions, thrermoregulator

 

temp--is big, 98.6, but without temp, metabolism going to go nuts, ability to circ O2, metabolism, going to die if hindered --too high or too low

 

pressure--why pressure? important for breathing, transport--no one ever talks about BP in good context, always hypertension--BP necessary because without it, how would we circ blood, filter nutrients out of capillaries into tissues

 

respiration--must be enough pressure to drive oxygen out of air, into our tissues,

 

"homeostasis

 

maintenance of a stable internal environment, i.e., balance

 

dynamic equilibrium--we operate around various set points that fluctuate when exposed to various stimuli

 

if we fail to return back to our normal set points, disease and sickness ensue"

 

what constitutes life, what life is, homeostasis is a big, not well-understood concept

 

we strive for on day to day basis==

 

phys balance

 

dyn equil. -- 98.6F your temp goes up and down, all during the day

 

go outside in cold weather, your body tem goes down

 

body water levels maintained by monitoring sodium levels, if osmolarity drops below certain point, body salts get too high, we get dehydrated, and need to get fluid back into our system--

 

certain set points that we need to survive=-homeostasis maintains balance around those certain set points how do we know what those points are?

 

always fluctuate around set points, but if we fluctuate too far, and don't get back to the set point, that's some form of disease

 

98.6F--temp goes down in cold air, so physiological mechanisms protect us, and help us reverse the drop in temp

 

body water level by monitoring sodium levels, osmolarity drops, salt too high, dehydrate, have to get water back in system

 

how do we know what a "normal" body temperature is, what a normal sodium level is, set points correspond to lab values among other things

 

nutrient levels, metabolism, what organ system is responsible for constant monitoring of this?

 

the most important system in human body is nervous system. some systems self-regulate to some degree, but regulation of body systems is the nervous system's job

 

 

if we fail to return back to normal set points, sickness occur--BP goes up and down, sit, stand, walk run move around, BP up to meet increased demand on body, as we age, BP tends to rise. we have mechanism that tend to compensate, but if those mechanisms fail, that's high BP

 

if our own systems fail, that's where medical intervention comes in

 

if body can't regulate BP, pills prescribed--bring in Olney at this point--if we need help to get physiology back to normal

 

maintain balance through feedback loops

 

"maintenance of homeostasis

 

always exposed to internal and external stimuli

 

requires constant monitoring by the nervous system

 

main form of regulation is through feedback loops

 

two loops: negative and positive feedback"

 

 

some organs do kind of self-regulate, like pancreas self-regulates insulin secretion, for most part in general, nervous system regulates everything

 

when nervous system detects changes in body, it needs to "figure out" (metaphorically) how to return to normal.

 

uses feedback loops

 

"negative feedback loop

 

three components: receptor, control center, effecter organ"

 

loop: something circular

 

negative most common regulatory mechanism in human body

 

receptor, control center, effecter organ

 

neg feedback begins with receptor, specialized cell or group of cells in nervous system, whose job is to detect changes--stimuli--stimulus, singular--factors that upset or disrupt physiology, changes in environment

 

all these receptors do is constantly wait for a stimulus

 

receptor detects a change, generate impulses to control center--main

control center in body is brain--central nervous system is brain and spinal

cord. receptors pick up on changes, send info about changes to control

center. control center (CNS) "develops" "plan of attack" for bringing situation back to normal (xref with innervation)

 

communicates with effector organ. effector organ carries out right response to get us back to normal set point, receptors, control center, effectors

shut off, because continuing to correct would over compensate, and take us in the wrong direction (tacking in a sailboat)

 

example: classical example: thermostat. cold air comes into house, thermostat set at 70F. 0F air comes in for 3 minutes. cold air came in, now house temperature of kitchen lower. as a result, something picks up on this, thermostat is receptor as well. temp to 65F, thermostat detects.

thermostat sends signal to heater, turns heater on. heater starts pouring out heat, only until gets back to 70F. then shuts off so house doesn't get too hot above 70F

 

 

overheating compared to hyperthyroidism. if we don't shut off response, that could kill us, oversecrete hormone while trying to get back to normal.

 

BP: say BP goes up from 120/80, 145/86 mm Hg. we need to get it back down.

if exercising, ok, but don't want it that high at rest. there is a baroreceptor (baro means heavy or pressure). the baro receptors are in carotid arteries in neck in carotid sinuses, sensitive only to changes in BP

 

 

 

 

BP up, baroreceptors detect it, communicate with control center. control center in this case is brainstem. effector organs in this system are heart and blood vessels (arteries).

 

heart rate will respond to high BP by going down, output of blood volume pumped out will go down. are we going to increase dilate or constrict decrease diameter of arteries down HR and dilated arteries with less pressure will make BP go down dilated arteries easier blood flow, then entire response shuts off at reset to 120.80

 

what happens if gets too low? pass out, bc brain not getting enough oxygen

 

carotid sinus massage

 

 

vasovagal syncope response to high-stress situations.

 

orthostatic hypotension

 

negative feedback is most common regulatory mechanism in body why is it called negative?

 

negates or changes a stimulus--back to normal and then shut off when get back to set point.

 

 

"positive feedback loop

 

can be life-threatening"

 

this is what we call an amplifying cycle

 

positive feedback is good but can be life-threatening as well, because it just keeps getting greater and greater and greater over time--there is no automatic shutoff valve, like there is on a negative feedback system

 

like neg, has to be some kind of stimulus that triggers it to begin

 

here's the difference

 

example childbirth--once uterus stretches to certain point, it starts generating active nervous potentials to brain, and the brain is going to respond by releasing hormone called oxytocin

 

uterus got stretch, stimulus is baby in this situation that stretched uterus, oxytocin makes smooth muscle of uterus start to contract, it's a labor contraction, what happens with labor contractions over time, they get worse, more intense, they do not get more pleasant over time, intensity goes up, and the amount of time in between the contractions goes down.

 

start out 20-30 minutes apart, by the time it's time to give birth, they're about 20-30 seconds apart. so there's a stimulus that activated the response, but the response continued to enhance, it got greater and greater and greater over time.

 

 

the only thing that's going to shut off a positive feedback loop is when the stimulus--in this case, the baby--is removed from the body

 

 

removal of stimulus turns off positive feedback

 

fever another example, this can be threatening,

 

you have pathogen within you

 

big initial spike in body temp, maintain high body temp, or slowly rises,

if body temp gets too high, it can kill you

 

if body temp gets too high, requires medical intervention, or it will kill you

 

my fever story

 

blood clotting mechanisms is pos feedback mechanism--too many clots stuck in circulation can impeded blood flow to essential organism somewhere

 

my blood clotting story

 

 

problem is, if too intense of stick around too long, can threaten our life, but it is a kind of feedback loop

 

you have the stimulus (stretch receptors in uterus picking up on presence of baby_

 

communicating with control center of brain on this

 

 

the difference here is the brain is continuing to amplify an amplify and amplify, making the response greater and greater and greater until the stimulus is gone

 

neg--stimulus triggers response to get back to certain set point, then stops--you can't get rid of body temperature or body water, can['t get rid of stimulus itself

 

pos & neg fb--we use these to maintain and regulate homeostasis--physiological balance

 

this is what our everyday life revolves around--keeping ourselves balanced, keeping all our set points in check to keep ourselves alive

 

topics and concepts you need to understand

 

understand difference in levels of analysis, claims about "balance", what has been shown and what hasn't, semantics
