Recently two Mayo trained orthopedists recommended the Dynasplint, which I already had. I am using it a few hours a day and I do think it is helping a little with my extension. I’m going to keep it up. It’s hard to walk without 0° extension. Hurts my back and hip to do so. If I feel it is successful, I will try the bending Dynasplint. My insurance pays for it, so what have I got to lose.
