Designed for people with severe arthritis, spinal injuries, wrist deformities or minimally functional trunk musculature. Finger function is not required. It is operated from a T-shaped toggle lever at the top, instead of a conventional trigger, and can be hand or mouth operated. A flexible arm support relieves virtually all stress on the radial side of the wrist while the wrist support prevents non-functional wrist extension. In the case of flexion, the support on the inside of the palm grip helps to control ulnar deflection of the wrist. The flexible supports are made of metal sheathed in soft plastic tubing. They can be bent to any shape by the user or therapist and moved from one side to the other to accommodate left and right hand use. Folds to 20 (50.8cm). A hook-and-loop fastener button latches the halves in the folded position. Weighs only 11.5 oz. (.326 kg).
