Whenever you have an injury to one leg, up with the good and down with the bad is what a physical therapist will tell you about how to climb steps. You should go up leading with the good leg and go down leading with the bad leg. The same goes for hemiparesis after a stroke. Hemiparesis is one-sided weakness and will be the term used after a stroke for being weak on one side. I wasn’t really weaker on one side but the ataxia made it very hard to coordinate the movements of my right side. When I first stroked, and for a long time afterward, this is how I would climb up and down steps. I would hold onto a railing with my left hand(the “good” hand) and lead with the good leg going up, bring up my bad leg to the same step, then do it again. Going down steps I did the opposite. So for a while I was climbing steps one at a time. I don’t have to do this anymore. I can climb steps reciprocally(one foot in front of the other on each step) – normally. I still hold onto a railing, particularly when going down, but I don’t have to take them one at a time anymore.
