Hi Hank @jesfactsmon
I admire your patience and open mindedness in trying to understand the concept of neuroplasticity. I also love your handle.
I have read the first book mentioned. I believe the concept is that the brain can be trained to "change". In brief, that means that one area of the brain, which originally had one function (such as controlling movement of one finger) can be trained through exercises to assume a different function (such as movement in a finger that has been compromised).
Incidentally, I don't think the book claims that the technique causes the brain to grow new neurons. It does claim that the technique causes existing neurons to assume new or different functions, by changing the connections between existing neurons.
While a promising and interesting idea, I do not think it has been "universally accepted" by all experts.
I also don't think it's helpful on a forum such as this to universally deride doctors, nurses, "big Pharma", etc. (the usual suspects) by claiming they are simply greedy, or interested in blocking new treatments to make money. It is particularly appalling to compare them to the tobacco industry.
As you have observed, the medical treatment of PN is currently not particularly efficacious, which understandably leads to sufferers trying to find successful treatments on their own. Unfortunately, this often leads to people trying untested, unproven and sometimes useless or even harmful substances or devices. I'm not necessarily putting neuroplasticity in that category.
"Big Pharma", etc. are certainly not trying to block the development of a successful treatment of PN. If one were to be developed, it would be a blockbuster drug for the pharmaceutical industry, and a relief for the doctors who have to struggle with patients they often cannot help.
Incidentally, PN is not the first cause of death in older people (by falling). Accidental death is about 10th on that list. The main causes are heart disease, cancer, stroke, in that order.
Good luck with your quest. If you find something that works well, please let us know.

Hi @jesfactsmon
I have experienced the effects of Neuroplasticity for Ataxia (balance) problems. I staggered when I walked and bumped into walls, and required a cane to prevent falls. My doctor sent me for Physical Therapy (at a local hospital well known for Rehabilitation for severe accidents and brain injuries called Mary Free Bed in Grand Rapids, MI) for Balance and Gait Training. The DPT (Doctor of Physical Therapy) I worked with explained that you can retrain the brain through PT. I used bands to strengthen my ankles and muscles in my lower legs, used balance devices and stood in a corner (to keep from falling) while practicing balancing on one leg at a time. I also did calf stretches on a wedged board that is similar to doing calf stretches before running where you are leaning towards a wall from a few feet away with one foot flat on the floor. I also stood in front of my kitchen sink with the cabinet door open so I could touch the toes of one foot on the shelf for stability while balancing on each leg to improve my balance. It worked and my Ataxia improved where I could walk without a cane.
