Abstract
A wrist exerciser has a rigid platform to receive a person's wrist, and a fabric support to hold the wrist to the rigid platform. A hinged arm is pivoted to the rigid platform and is fixed to the fabric support at the palm of the hand, so that as the hand is moved in the extension direction, the hinged arm moves. A rod is pivoted to the hinged arm so that, as the hinged arm moves, the rod moves proximally of the person's arm. A spring resists the motion of the rod, so the exercise is against spring tension. A heated or cooled pad can be placed in the arm support to provide therapy during exercise.
