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.

Sold

It's all over. Almost. Will be, once all the subject-to's are gone, by May 29th. Then I will be officially in transition, not just preparing to be in transition.

I'm pretty satisfied with the sale. I got nearly as much as I was asking, and the buyers were people who knew what they liked and moved decisively, didn't burn a lot of fuel dithering around wasting everybody's time and patience. They came/ they saw/they bought, all in the space of a single day.

Hurray.

It looks like I'll be able to go where photons shine all year round, about mid-July. If I'm careful with money, I'll be able to afford a longed-for, self-assembled "sabbatical," during which I can rest one part of my brain (the treating part, which is so automatic it will never forget how) while I work on developing the conceptualizing, writing part. I plan to write furiously while I have the opportunity. Maybe less blogging, more actual book-writing.

"The pain is gone"

To me, an old-fashioned human primate social groomer who has always leaned harder toward the "therapist" side of treatment rather than the "physical", but who uses manual therapy as my main intervention, the advantage of deep science-based pain models like my favorite, the pain neuromatrix model, is that one can remain connected to one's patient (i.e., in good therapeutic contact) while explaining to them what their experience of pain, or in this case radical pain relief, might mean, regardless of how strange it may seem to me or may have seemed to them.

Here is a diagram, famous by now I'm sure, of Melzack's neuromatrix model. Click on it to make it bigger, so you can read the detail.

I often haul out this little diagram and sit down with a patient, because a lot of times, simple handling isn't quite enough - they need answers.

Case in point: last week I saw a young woman for the first time. She had been sent to me by her massage therapist (who I've known for years) who had worked with her for many months. Let's called the patient Rosie (not her real name).

Rosie had had a prior history of low back pain for ten years, for which she had gone to a chiropractor semi-regularly. She had worked as a fund raiser for some outfit, until about two years ago; while nursing a sprained ankle (and on crutches) she was in a car accident. Now she had back pain, sprained ankle, and neck and shoulder pain. She was unable to do her fundraising job anymore and had had to quit.

She had endured persistent neck and shoulder pain for two years in spite of seeing 36 of the finest manual therapists, both conventional and alternative, that Canada has to offer, in two different provinces, and having attended a modern pain clinic.

Then, to her surprise, during a meditation retreat in December last year, her pain vanished. All of it. Gone.

Emboldened, she began a vigorous yoga program, and inadvertently overstretched something. Bam. She had felt instant leg pain and a lot of weakness in the quads. This had persisted beyond the massage therapist's expertise, and was why she had been sent to see me.

I learned that after she had given up fundraising after the MVA, she had become involved in an experiential psych counselling training program, where they let her learn from a physical position of comfort, i.e., horizontal.

At visit #1 I had taken her history and provided some manual treatment, some very rudimentary pain education, and showed her a neural glide to do for the leg. She'd been happy for something to do - anything.

Yesterday at visit #2, I was ready with a neuromatrix diagram and was planning more in depth pain ed.

She arrived.
I asked how she was doing, and she said, "Fine, I'm all better."

(I was thinking,... huh? Did she go on another retreat?)

I asked how she had managed it this time, and she replied that the evening prior she had invited two shamans in to work on her, and they had, with burning herbs and drumming, and lots of touching. Before they left, they had pronounced her cured.

And sure enough, she felt that way. No pain.

She really did seem better, could walk better, move better, sit comfortably, breathe better.. Wow, I thought. "Good for you," I said.

"Well," she said, "I still feel some stuff..."
"..It looks like the stuff you might still feel doesn't bother you anymore - is that how it feels?" I asked.
"Yes," she replied, "I still feel some stuff but it doesn't bother me at all. I didn't need to come today, but it was too late to cancel my appointment."

We had an hour to spend, so I decided to stick with the plan; I asked her if she was interested in learning some things about pain. She said yes, so I invited her to go through the neuromatrix diagram with me. We sat down and I began explaining how the center circle with circular arrows represented the entire nervous system, how it was always processing even at night during sleep, how it was more of a verb, therefore, than it was a noun, how the diagram depicted the movement of this neuromatrix through time... how it had three main inputs on a spectrum that ranged from mental (cognitive evaluative) to physical (sensory-discriminative) to physiological (motivational-affective) and three main outputs, one of which just so happened to be pain, which could be influenced by any of the three inputs and which in turn influenced the three main inputs plus the other two outputs...

As we wandered through the diagram, I plugged in pieces of info she'd given me, she asked questions, we talked about treatment crucibles, safe containers and catalysts, symbolism and shamanism, meditation and movement forward. During her shamanic experience she had had a great deal of novel sensory-discriminative input, through all her senses, not just kinesthetically. I told her it sounded like it had been enough to get her neuromatrix off the square it had been stuck on. I pointed out, based on the prior meditation/pain relief experience, how much more her particular pain matrix seemed to respond to shift of cognitive input than it did to sensory-discriminative input. I mentioned that for most people, sensory-discriminative input of the physical kind was often sufficient, but that she'd burned through 37 manual practitioners of various kinds, including me, without much help, and she nodded..

She told me this was all making more sense to her now.. that she was someone who just didn't "get" things through only her body, the way most people can if some reasonable sensory-discriminative input of a novel sort is provided... Instead things had to make sense to her through her emotions/mind.

Apparently long ago some other PT had loaned her the book "Explain Pain", for a few months, and she had diligently made notes and some photocopies, but it had never quite sunk in or gelled. Now it was finally starting to make sense. She said, "I wish I could read that book again. It was really good, as I recall." I replied that she could buy her own copy if she wanted.

We discussed rehab, and I told her about some options, but that wherever she went, to stay in complete control, not let anyone rush her, and to use "graded exposure" and "pacing", concepts she already knew about.

I showed her two chapters from Pain: A Textbook for Therapists and she took copies. She said this would help her learn the neurobiology for when she herself would be a therapist, counselling pain patients. I mentioned she would be able to buy this book online as well - that buying these two books for herself would be much cheaper in the long run than seeing a bunch of expensive therapists for sensory-discriminative input that her particular brain seemed to not be wired to be able to easily accept. She agreed.

I worked with her leg for a little while, and unlike the first time, this time she remarked on feeling heat and movement in the thigh, and non-painful sensation connected to the leg in other parts of her body. I asked her if she could do an active straight leg raise after, and to her surprise, she could.

She left very pleased with all the progress she had made in one week, by her own efforts. I didn't need to see her again in my opinion; her downregulation was well and truly hooked back up. She's away to her next adventure, all in one piece again finally.

Way to go, Rosie. Way to go.

Michael Merzenich, On the Brain

I've been exploring a site called On the Brain.com, a blogsite hosted by Michael Merzenich:
Dr. Michael (Mike) Merzenich is the Francis Sooy Professor in the Keck Center for Integrative Neurosciences at the University of California at San Francisco. In parallel with the landmark studies of his UCSF team in the science of neuroplasticity, he has worked with other scientists, medical specialists, psychologists, engineers and other technical specialists to develop training programs based on this science, and designed to improve the behavioral capacities and neurological abilities of children and adults in need of help. Almost a million individuals have now benefited from the use of these programs.


On his site I found a video about a man with traumatic brain injury whose cognitive function became improved via some mental exercises. I was impressed - thought I'd share it here.
