To do this the pad performs two important functions. ��First, it absorbs 30-50% of the vibrations from that result from repetitive motion or sudden impact and causes pain and inflammation to the muscles and tendons. ��Second, it heats the muscles which increases blood flow and heals the injured or arthritic area. Conforming to your body the pad improves the comfort level so that it can easily be worn day and night which speed up the recovery process.Clinically proven in the Journal of Shoulder & Elbow Surgery, Coopercare proves full efficacy in spite of unrestricted activities in sports.Competitively priced, the pad works every time you wear it.
