Last night at cross fit there we were supposed to do a box jump. Everyone was doing it, but even though it was only about 6" off the ground I just could not do it. So I ended up just stepping up and down one foot at a time.
As far as your EMG, I am not sure if that can totally rule out MS. My docs have thought I have it. I have lesions on my brain, but no bands showing in my spinal fluid. I have not had an EMG done.
Good luck. Please know you are not alone in this struggle.
I trip, run into things, bad balance, fall. I describe my body as being a pinball in pinball machine just bouncing on and off things.
My rhuemy has decided to put me in physical therapy for balance issues and leg weakness. I start next week.
