Guest post at ForwardThinkingPT.com on Dermoneuromodulation

This is a copy of a guest post on dermoneuromodulation Joe Brence asked me to write for his blog, ForwardThinkingPT. com published earlier today. It contains the DNM roundup from yesterday.


I want to thank Joe for the opportunity to write a guest post for his blog about dermoneuromodulation. Even though I’ve been writing about it in one way or another for many years, it is hard to encapsulate this in under 1000 words and still be able to convey what I think needs to be conveyed. So, what I've done is present a brief outline, with a list of links at the end to blogposts, which discuss the topics in more detail, and which link to other posts for even more detail. 
HISTORY OF THE TERMThe term originated with a little bit of help from SomaSimple friends in the mid-2000’s as I struggled, as we all struggled, to become more conscious and articulate about manual therapy in general, and discuss problems inherent within it. David Butler’s neuromobilization workshop in the late 90’s, and discovering Melzack’s neuromatrix model of pain in 2003, plunged me into cognitive dissonance from which I have yet to emerge. In 2006 a colleague at the U. of Saskatchewan, and I, began a case series study (scheduled for write-up/ publication this year). Results indicated "weak but statistically significant" results, about what one would expect from a case series on any kind of manual treatment.
MEANING OF THE TERM: The word “dermoneuromodulation” simply means skin/nervous system/change. It does not imply that the practitioner is the one “doing” something called “change” “to” something anatomical in another person. It does not exclude the nervous system of the patient as change agent under its own auspices, thus DNM is as close to being an interactive model of manual care as opposed to an operator model as any kind of manual therapy approach can be, while still handling bodies of other (live, conscious) people. Other than “skin”, the surface all of us touch regardless of whatever else we might conjecture about what we are doing/affecting/handling, sensory endings, and cutaneous nerves, there is no mention of “tissue”. 
OPERATOR VERSUS INTERACTOR MODELS IN MANUAL TREATMENTI have considered this quite closely, and all I want to say about it here is that I think, in the clinic, one should know when one is in one mode or the other, and be fluent in both. 
CONSIDERATIONS IMPORTANT TO SUCCESSFUL TREATMENT OF ANY KIND:
NERVOUS SYSTEM: Bearing in mind that we are treating live integral humans, conscious, awake, and usually presenting with pain , we have to (I think) consider their nervous system, and focus on creating a context that will favour their ability to change how they think and feel about their pain. We should share whatever information we may have about what “pain” is, how it behaves, with the patient, so we can both be on the same page. I wrote an extensive series of blog posts about developing the therapeutic container, called “New treatment encounter”. I present the nervous “system” as a signalling entity woven throughout the body, derived directly from the embryonic “builder”, ectoderm, continuous in a human adult from skin cell to sense of self. 
NEUROMATRIX MODEL: New Treatment encounter Part VI is specifically about the neuromatrix model, understanding it’s use for treatment, getting clear about our inputs (including manual therapy), and what we want to see happen with outputs. An elaboration of that can be found here
TUNNEL SYNDROMESPain experienced as persistent or recurrent and relatively localized (i.e., most mechanical “MSK” pain) is conceptualized as nerve pain.
NEURODYNAMICS: Peripheral nerves come all the way out to supply skin, sooner or later, proximally or distally, making them fairly easy to affect mechanically regardless of where or how one makes contact with skin. 
PERIPHERAL DISSEMINATION OF CUTANEOUS NERVES: A dissection of cutaneous rami done in 2007 revealed the macrostructure of cutaneous rami to the underside of skin
SKIN CONTACT: Skin is well supplied with exteroceptive receptors of all sorts and fibers that transmit information to the brain using fast dorsal column pathways and non-nociceptive slow spinothalamic pathways, to centers in both the internal regulation system and the primary sensory cortex of the brain. As long as the handling is mostly non-nociceptive, it will be physically safe for most pain presentations. A sensory ending known as the Ruffini ending is particularly capable of transducing lateral stretch to skin. It is slow adapting, which means it will actively fire the entire time a skin stretch is held, allowing the nervous system time and stimulation to alter its motor output and pain output at spinal cord and more rostral levels. 
IN SUMMARY: Research in manual therapy tells us that there is little or no interrater reliability for palpation or application, little or no agreement on what constitutes the overall best approach, and that success in terms of favourable outcomes depends a lot on context and treatment relationship. Applications differ widely in amount, intention, length, depth, angle, and zone of contact. I am of the opinion that manual therapy is optional, yet often may be optimal, to acheiving successful outcome in terms of pain reduction and movement improvement. The real trick in treatment is to leave the locus of control with the patient while still providing them with professional physical contact as required, by them, as individuals, in the moment, and within the context of a therapeutic relationship. I do not know what should be ruled out in order to show the world that manual therapy is useful; I only think that these items I’ve discussed should be left ruled in.

Dermoneuromodulation: Ascending pathways

This part of the neuroanatomy of touch, or exteroceptive skin reception, of manual therapy contact, has been well worked out. According to Olausson and his colleagues, information from Ruffini endings in skin, which respond to lateral skin stretch, and will continue to fire as long as the stretch is continuously applied, travel along dorsal column pathways, and reach beyond S1 to dorsolateral prefrontal cortex.  (4)


Dorsal column pathways are fast. They go straight through to S1.



The spinothalamic tract handles ascending traffic from thin, unmyelinated fibers. These fibers are "C" fibers. Nociceptors are among them, but C fibers are not restricted to only nociception. (1-5)

These pathways are slow. They transmit nociceptive information, AND, also, pleasurable sensation.



The main somatosensory map in the parietal cortex (S1) is non-judgemental - it records intensity only. 




The affective network, the salience network, the threat-detecting "critter brain"(which includes the insular cortex and anterior cingulate cortex, part of the descending modulation/internal regulation system) is very judgey about contact. As manual therapists, if we know about this we can explain it to our patients so that when we touch them, they will be prepared in their "human" brain (4), for the contact we make with them. Then when we make that contact, they will be able to distance themselves from, or engage with, the sensations, as may be appropriate in the moment. They may even be better able to guide us, to help us help them better



This is a picture of all the parts of the internal regulation system, and a description of its awesome powers. I call this the "critter brain." Our manual therapy should be mostly about helping patients win this part of their own brains over, in my opinion.

Dermoneuromodulation: The neuromatrix model of pain

I've written extensively about Melzack's Neuromatrix model of pain, here (on a wikipage), and elsewhere in this blog, most recently here.
The main story is to realize, to grok, to wrap one's head around the fact that pain is an output of the brain, not an input. Details are still arriving.
Here is a picture of the updated model.
What we want is to accomplish the following:

DECREASE PAIN OUTPUT, IMPROVE MOVEMENT OUTPUT,
WHICH IN TURN, MAY AFFECT STRESS OUPUT POSITIVELY


Or, this is good too:

PAIN EDUCATION CAN HELP PATIENT FEEL THEY HAVE LOCUS OF CONTROL,
WHICH MAY REDUCE THEIR STRESS LEVEL





Overall, what we REALLY hope we can do (with manual therapy), is this
ADDITION OF CONTEXT-APPROPRIATE MANUAL THERAPY, CONSISTENT WITH PAIN EDUCATION



We want our contact to be congruent with our education about the neuromatrix and pain. We want our contact to help, not hinder, the process of resolution of pain and movement impairment DUE to "pain".  We want it to help reduce bad stress, but maybe the patient needs to use their own positive "stress response" (from their own locus of control) to get themselves free from pain. We want to augment the teaching we did (the magnifying glass in the diagram). 


It's best if our physically applied input is kind, light, warm, non-nociceptive, steady. Skin stretching is not a bad way to proceed. If someone has fierce allodynia, you might try a mirror box and a soft sable makeup brush, applied to the skin on the opposite side, or an adjacent part of the somatosensory representation. Give their brain time to figure out the input and respond. Sometimes this means light contact over a longer period of time, not more pressure, or faster pressure. 


Dermoneuromodulation: Neurodynamics, tunnel syndromes, cutaneous nerves.

Peripheral neurodynamics


In 1998 I attended David Butler's "Neuromobilization" workshop. I must admit, I was not orthopedic-y enough to be about to translate everything he was teaching into a "spine-out" logical flow. I admit to always having been an outside-in sort of interactor therapist, both physical and manual. I was called on the rug during clinical training for thinking it made sense to work with stroke patients by working with their hands first instead of their trunks. But's that's a whole other story.
Michael Shacklock, another ortho person turned neurodynamic guy, was dedicated enough to bring back to life the original book by Alf Brieg, Adverse Mechanical Tension in the Nervous System. (It's mostly about spinal cord neurodynamics, of more interest to ortho-types of manual therapists, deep into structuralism, steeped by it, than it is to me, who has always stayed more outside the spine, conceptually and operatively. I prefer to affect the nervous system from its sensitive surface membrane, also ectodermal in origin, i.e., the epidermis and related exteroceptive and interoceptive capacity of its many sensory endings.)


Yet, as I sat in Butler's class, I felt my manual therapy worldview cave in - everything he said in terms of nerves, what they were about, how nociception became established, then amplified inside them, inside the system itself, made such sense it took me over completely, and I've been a nerve girl ever since, never gave "tissue" a second thought after that, especially fascia. Everything he said was congruent with another body of knowledge I had examined, embryologic development. You know those pictures that fool the brain into seeing two things at the same time, and you think you see it one way, but suddenly it looks like something else entirely?
That was me. I hadn't seen the rabbit for looking at what I thought was the duck. Abruptly, I graduated from what I call my "mesoderm" phase, and plunged headlong into an "ectoderm" phase from which I'll never emerge. Because at least now we're talking about the right kind of 'tissue' -  skin, nerve, neural container, spinal cord and brain - all direct derivatives from ectoderm, all concerned with "management" of an organism. Not structural space-filler/moveable puppet part and their glued-together connectedness (bone, joint, muscle, tendon, ligament, fascia). It's all a lot more complex than this, of course, with different parts of the nervous system doing different jobs, and different parts of the brain running various subsystems of visceral afferent/efferent function, autonomic function and so on, but at least now, we no longer need to entertain the crazy idea that innocent tissue "causes" anything like "pain" or try to prove somehow that there is any sort of correlation between what we might do with our hands, when working with people, and any sort of pain reduction, based on having magically affected some sort of deeply buried "structure" with some goofy operator model of treatment, whether vitalistic or structuralist - that dualistic Descartes combination. It's about nervous systems interacting with each other, and stress reduction. How simple is that?


In 2007 I was fortunate enough to gain access to an anatomy lab and dissect out cutaneous nerves, which were the ones that interested me! They have feelings too. In live people that is. Michael Shacklock published a few of the photos in his newsletter. I wrote up a paper about it that is yet to be published somewhere. But, at least, it's now been done, and I figure, pulling gently on these little rami likely has some sort of beneficial effect on intrinsic circulation well up into the nerve they are part of, all the way up to the first synapse (neurologically) or into the dorsal root ganglia, maybe (physically, mechanically), especially if you handle body parts simultaneously, and make treatment stress free for the patient by eliminating gravity as much as possible.


Which brings us to the topic of tunnel syndromes.


I think that covers the topics on the right side of the dermoneuromodulation diagram, under "physicality".  These are the considerations I have while treating as a manual therapist. I'm still "operator" model enough to need to think about something physical as I treat. I'm not zen enough to be completely content-free, pure interactor.  Not yet anyway. But I'm a lot less "physical" and a lot more "therapist" than I was, once upon a time.

Dermoneuromodulation: Where it came from

Introduction
Dermoneuromodulation represents my personal effort to make sense out of manual therapy in general. Manual therapy gradually evolved. 
Given the advances in neuroscience in the last couple decades, and concomitant advances in pain science (although slower), ideas upon which manual therapy bases itself are due for overhaul, in my opinion, by starting further back than mere production of ever more outcome studies. Todd Hargrove, a thoughtful blogger, nails it perfectly in his post, Souless bodies and bodiless souls (3); 
"..vitalism and structuralism are two sides of the same dualistic coin..Vitalism is an example of belief in a “bodiless soul.” Vital energy is considered to be an animating force that exists outside the physical realm and is not reducible to it. And structuralism is the metaphorical flip side of the coin – the tendency to treat the body as a physical object, as opposed to an intelligent agent with feelings, thoughts and intentions.
Scientific study of manual therapy
Manual therapy teaches a bunch of stuff about "proximate cause (1)." Manual therapists want to, and are taught to, take on the role of "operator(2)", not just humble interactor. 
Examining
the questions themselves 
We seem to think that manual therapy can't be studied scientifically unless it can be isolated and specific effects determined. Problems arise with study designs, and poor interrater reliability seems ubiquitous. Even when separate outcome studies are good, the results don't seem to be able to stand up to statistical analysis very well (16,17). Could it be we asked wrong questions in the first place? 


Rethinking the problem of pain
People who come for manual therapy come because they are experiencing pain (or some sort of discomfort with their body), usually. 
Melzack(5) puzzled over pain for decades and finally concluded it was not an input, it was an output (see neuromatrix diagram here). He at least got us (manual therapists) that far, by separating nociception (an input) from pain, a brain output - he de-Cartesian-ized pain - not an easy task; it meant moving in opposition to 400 years of medical science which claimed pain was a bottom-up phenomenon (and still does, as do most forms of manual therapy). Melzack realized pain was biopsychsocial in nature, something that had to do, perhaps, with being lost in one's own embeddedness into, and ideas about, externalized reality, or not sufficiently aware of one's own physicality, or both, not able to detach from either when desired. His model is brilliant, clinically useful, and best of all, non-dualistic: we treat conscious, living people after all, not anesthetized patients. We are forced to interact - we do not have the luxury of (merely) 'operating' (2). 
Another perspective on the same matter is offered by Quintner(6), who argues that far from being something that can be disassembled into bio-, psycho- or social components, pain is an aporia, which is to say... 
"...a space and presence that defies us access to its secrets. We suggest a project in which pain may be apprehended in the clinical encounter, through the engagement of two autonomous self-referential beings in the intersubjective or so-called third space, from which new therapeutic possibilities can arise."
I see parallels between manual therapy with its attendent problems, and what I found in a revealing blog post interview (about psychiatry) with Richard Marken, discussing Perceptual Control Theory (7): Instead of looking at a human being from "outside" that human being, and his or her own "behaviour" (including pain "behaviour") as a problem of input/output, we could try to look at the behaviour itself as a process of control, by the organism itself/himself/herself


So, rather than flailing about with manual therapy as my only tool, a tool, furthermore, honed and contaminated by centuries of Cartesian misunderstanding, I adapted myself to new information. Now I consider manual therapy to be just a tiny part of the process of interacting with people who have come in as patients with pain problems. Providing them with a boundaried therapeutic relationship is far more useful to them in the long term. The hands-on part may be both optional for some and optimal for others. But all  PT patients will benefit by understanding simple facts about the nervous system and pain science (4) (however awkwardly confused, bottom-up, Cartesian such information may still be), couched in a framework such that it lays no blame on them or any of their body parts/mesodermal derivatives for having it, and at the same time leaves them with the locus of internal control they need for extracting their own conscious awareness out of it once more.


Is a new awareness is dawning in manual therapy?
I think maybe there might be (8-15).

Dermoneuromodulation: Ruffini sensory endings and dorsolateral prefrontal cortex


I do not think any of the above points can be ruled out, no matter what "kind" of manual therapy one was taught. Yet none of these considerations are commonly taught by current manual therapy institutions or teachers to my knowledge. 


I found a paper lately, Processing in prefrontal cortex underlies tactile direction discrimination: An fMRI study of a patient with a traumatic spinal cord lesion.
"We have investigated cortical processing of tactile direction discrimination (TDD) in a patient with unilateral tactile disturbance due to spinal cord lesion. The patient R.A. (male, 45 years old), suffers from a traumatic dorsal column lesion at the level of Th XI-XII on the right side. He was instructed to report the direction of 2mm long skin pull stimulations applied in a proximal or distal direction on his right or left lower legs during functional magnetic resonance imaging (fMRI). Although R.A. considered himself to have nearly normal tactile sensibility, testing showed severely disturbed TDD on his right leg whereas results were within the range of healthy subjects on his left leg. For both legs TDD activated an extensive cortical network that included opercular parietal area 1 (OP1) of the second somatosensory cortex (S2), as has previously been observed in healthy subjects. However, dorsolateral prefrontal cortex (DLPFC) and anterior insular cortex (AIC) were only activated for the unaffected (left) leg where TDD was normal. A revisit of previously published data showed that healthy subjects consistently had TDD-related activations in DLPFC and AIC. However, in several healthy subjects AIC, but not DLPFC, was also activated for skin pull stimulations per se without the TDD task. Thus, the patient's data, in conjunction with the previous results from healthy subjects, suggest that DLPFC processing is important for tactile decision making based on proper tactile input."
Their subject was an individual who had sustained a cord lesion two years prior (due to a mishap by a person providing him with epidural anesthesia for a colon operation). The lesion was at the level of T11-12, 12mm long and 2mm wide, to the right of the cord medulla, in the dorsal column. This left him with sensory deficit - the point of the study was to determine exactly what sort. He had right leg pain, and some difficulty running, although he could still run. 
The authors used a device that could apply skin stretch (2 millimeters) in a directional, quantifiable manner, to hairy skin on the human leg, and looked at that was happening in the brain at the same time via fMRI. To the right is a picture of it. It went into the fMRI machine with him. They glued a 2-mm rod to the lower leg with which to pull the skin. The paper describes all the details of how the testing was conducted, how much, how long, how many times, etc. 
From the paper: 
"TDD for a high-friction stimulus (i.e. lateral skin pull stimulation) utilizes information about patterns of skin stretch [8,18] mainly signalled by a population of slowly adapting type 2 (SA2) afferents (commonly regarded as Ruffini afferents)"
Could this be why skin stretching, or massage,
or any 'kind' of manual therapy,
is often effective for reducing pain,
clinically, at least in the short term?
For purposes of manual therapy, what I extract from this paper is that they answered the question "what part of the brain reads tactile direction discrimination from Ruffini endings" - answer: Dorsolateral Prefrontal Cortex. All the other areas involved in touch processing were seen to activate bilaterally regardless of which leg was tested, but only the dorsolateral prefrontal cortex lit up on the right when the left (unaffected leg) was stimulated by directional pull, could decode the info and "represent" it accurately. His brain could do this when supplied with the information from the leg through the intact dorsal column but not when it was interrupted by the lesion.  
From the paper: 
"The DLPFC has been reported to be involved in sensory decision making [11]. In an fMRI study on a vibration discrimination task in healthy subjects it was found that the level of activity in the left DLPFC correlated to the accuracy of the perceptual decisions [21]. Our results showed DLPFC activation only for the patient’s unaffected (left leg) where he was able to perceive the difference in movement direction in TDD and thus gave more correct answers. Further, we found reliable activation of DLPFC in healthy subjects during TDD but not during skin pull stimulation per se. Thus, it seems reasonable to suggest that DLPFC is involved in tactile decision making based on proper tactile input [21]."
Just think about that for a minute: tactile decision making - not just sensing. 
Interestingly the authors state that they saw no activation of S1. It may be that S1 responds only to novel exteroception. Perhaps once the rod was glued in place, the S1 ignored it, and, perhaps Ruffini ending information bypasses S1, reaches the DLPFC through some other pathway connected to interoceptive processing, but only if dorsal column information is available in the first place to be sent there.

Neuroplasticity, neurogenesis baby!

Today while I was at the gym I became very interested in the experience one of the managers has had with a vibrating machine there. It's been there a long time, and so has she, but she only started using it three weeks ago. She uses it up to 20 minutes a day, just standing on it and holding on to the sides, letting it shake her at a very high frequency and tiny amplitude. Some days she only has time to be on it a few minutes. But I'm getting ahead of myself. Let me introduce her to you. I'm going to call her Susie (not her real name). She has given me permission to blog about her. 


Twenty-five years ago, friendly outgoing Susie was 22 years old, in good health. She was having a baby by C-section. Something bad happened, and she had a stroke that affected her left side. 


I met Susie 5 months ago when I started attending the little women's gym here in town. I noticed that she was unable to use her left arm, and that she walked with a limp. For all I knew, she might have been born with a disability. She does everything needed for her job, which includes measuring for inches lost on all the clients at the gym, with her right hand, and also takes care of her family, runs a house, doesn't let anything stop her. 


Today, she started chatting about how she is regaining function in her arm, and demonstrated a couple things - most of her movement regained so far is in shoulder girdle function - she can raise her arm up over her head while standing, in supine she can raise her arm over her head, can externally rotate, but not internally, not yet at least. But she can also bend her elbow to about 90 degrees. The thing she's most proud of is being about to support her weight on that arm in prone enough to enable her to do a "plank".  She showed me that her fingers have started to move a bit as well. 


All of this is after 25 years. And after being told that part of her brain that runs her arm was dead and would never recover. In typical Susie style, she wants to get back enough hand function to at least be able to flip a bird at the doctor who told her that. All this improvement in just 3 weeks, after 25 years, by using a vibrator platform. 


Remarkable, no? Never say never.
