A resilient wrist support and therapeutic hand exerciser device (10) for supporting the wrist of a person performing repetitive tasks with their wrist, hand and fingers, such as using a computer mouse and typing on a keyboard, and for exercising the muscles of the wrist, hand, fingers and forearm of the user. A mass of tiny glass spheres (14) having the consistency and appearance of a fine powder is enclosed in a resilient inner bladder (11) surrounded by a resilient outer bladder (12) and a thin layer of lubricating powder (13) is disposed between the exterior surface of the inner bladder and interior surface of the outer bladder to prevent them from sticking together, reduce friction therebetween, and allow relative sliding movement between the surfaces.
