My house is very wheelchair accessible... lots of floors with no carpeting, grab bars in the shower. I can stand up easily on my right foot/leg without my left foot touching the floor.
I have a wheelchair ramp to the house left over from when my husband lost his leg. And yes, it's my left ankle.
I was wondering why you said you couldn't drive... do you drive a standard?
I pull the wheelchair to the car door, open the car door, stand up on my right leg, swivel ~90 degrees counterclockwise and sit down on the driver's side. My left foot never touches the ground. In the car, my left foot gently rests on its side. I can bend my left knee-- the first splint I had from the ER I couldn't bend my left knee-- VERY inconvenient. Then I just drive... Back home, I reversed the process, got in the wheelchair, pushed with my hands and right foot up the ramp backwards into the house. Am I missing something? It could be that I'm being dense and not seeing something that you're seeing...
