Input:
I have carpel tunnel that had progressed to a point that it was affecting my elbow and shoulder. A nerve study indicated that I was a surgical candidate. As I was on two crutches for a knee injury, it wasn't really a feasible option at the moment. I saw these at the physical therapists and asked how they worked. I started with the yellow, worked my way up through the red and am currently using green resistance bar. It made a world of difference!
I still can't do crochet, bit my elbow and shoulder are no longer involved and I can do many things that I had despaired of ever doing again
