nope and I have had PT all my life for my Cerebral palsy which is simular to MS. and have friends that have MS and they also don't go through that.

I and they work on muscle stretching, and cordination activities like walking between handrails, going up and down a set of stairs, catching, throwing balls, but not crawling around like a baby.

I know they do that kind of reprogramming with stroke survivors who cant walk, crawl and so on but have never heard of it being used for CP and MS.
