Post polio syndrome?.

It's a real medical condition, although I'm not sure if that's what it's called.

I believe that is its name. It's a significant disease receiving little research as it should become extinct. If he has post-polio it probably won't much affect his ability to perform his job . His position brings enough like minded staff that he doesn't have to be very physical. Our problems with Mitch aren't his peripheral nervous system, but rather his central one.
