Last October I was diagnosed with patella femoral disease, otherwise known as runners knee. I had 6 months of PT until everything got shut down. Part of my PT included use of a Nustep machine. I continued with some of the PT that I could do at home. In May I started chiropractic. That and hemp oil gummies has taken the edge off the pain. I still can’t stand without assist bars or arms on chairs. I have access to a Nustep again and use it for 20 minutes 3 times weekly. I feel that I’ve lost my memory of how to stand. Any thoughts?
