Dragging my leg is becoming an issue

Apparently, I have a lesion in my brain on the left side. Nothing has changed on my MRI's for ten years, but my my leg still drags. Oddly, the foot-drop has gone away. However, I still have issues raising the one leg at the hip. I am losing muscle tone in the leg although I am quite muscular and push myself to move when when tired. Working on the eliptical at the gym, ride my horse almost every day, garden and tend to my chickens which is more work than you think! Swim. Does anyone have this issue of dragging their leg and may has some ideas on how to support it? Maybe through strengthening exercises and diet?
