An arm brace comprising an extendable band, such as an elastic strap, that forms a supinating tension band. The distal end the band has a looped section for a users wrist or finger for anchoring the brace, and the proximal end has a fastening device, such as a hook and loop fastener, for securing the proximal end to another portion of band after the band is wrapped around the forearm and stretched around the elbow and back towards the forearm. The extended band exerts a force that causes supination of the arm. In some embodiments, the inner surface of the proximal end of the band attaches to the outer surface of the band, and the looped section has a loop that closes at a notched section of the band, to provide proper comfort and positioning.
