Abstract: A hand stretching method and apparatus mimics a well known exercise to reduce the problems with repetitive stress injury. A body of resiliently deformable material has flat and parallel top and bottom surfaces, with a cutout at one edge of the body. A user's hand is placed on the body, with the palm of the hand spanning the cutout. By pushing down on the hand, the opposite sides of the palm are urged apart, opening the carpal tunnel and relieving compression on the blood vessels and nerves. A user may place one hand on each surface of the body and urge the hands towards each other for treatment of both hands simultaneously. The body is preferably made of an expanded polymeric material such as polyurethane. Layers having different compression factors may be utilized; and, darker colored surface layers of material may be adhered to the top and bottom surfaces so the surfaces will not readily show dirt.
