Resilient magnetherapy articles having a powder-like filler material including magnetic elements contained within a resilient bladder are disclosed for exercising the muscles of the wrist, hand, fingers and forearm of the user, and 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, while at the same time providing the beneficial effect of magnetic therapy. A mass of tiny glass spheres having the consistency and appearance of a fine powder is enclosed in a resilient inner bladder surrounded by a resilient outer bladder and a thin layer of lubricating powder 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 when squeezed in the palm of the hand. The tiny spheres provide low resistance to relative particle movement by rolling on each other upon an increase or decrease in applied pressure. When placed on a flat surface beneath the wrist of a user, the article deforms slightly and conforms to the underside of the user's wrist to form a comfortable cradle-like support as the downward pressure of the wrist increases or decreases. As the wrist is moved relative to the flat surface, the article smoothly rolls between the wrist and the flat surface to provide a smooth massaging effect on the wrist while maintaining wrist support.
