Abstract
Abstract An improved semirigid counterforce brace adapted for application on a user's forearm helps prevent and provides relief during tennis play of tendonitis of the conjoined tendon of the extensor communis and extensor carpi radialis brevis at the insertion into the lateral epicondyl, a condition commonly referred to as "tennis elbow". The brace includes a semirigid, perforated, fluid passing outer plastic backer and inner porous strap, e.g., of a fabric laminated with an open pore foamed urethane, and a strap attached to the brace and adapted to wrap around the subject's forearm, pass through a loop disposed near, but not at, one end of the outer surface of the backer sheet, and to be secured in place by cooperating fasteners, e.g., cooperating hook and eye [VELCRO (tm)] type fasteners.
