JAS Launches Its New Dynamic Product Line

My elbow injury was extremely difficult to rehabilitate, and I had lost all mobility.  I was fitted with a JAS brace within a month of my surgery, and the results were amazing.  In three months I  gained 35 degrees of motion and could do a ponytail behind my head.  I do not believe any other physical therapy sessions would have given me back the use of my arm like the JAS brace did, and for that I am forever grateful.
