, like Lori, I hope you get some helpful feedback from other community members. That said, not of the literature I came across on this topic was about exercising to maintain or improve MS related muscle weakness and spasticity. But, one point that kept coming up was that weakness after walking may indicate a progression of symptoms and physical therapy *might* help with that. I am not suggesting PT, per se, but it does seem to be one noninvasive treatment option that might help. Best, Erin, MultipleSclerosis.net Team Member.
