Abstract
Abstract An elbow hyperextension limiting arm brace spanning the elbow region when strapped in place on a person's arm holding the arm in a normal partially elbow bent attitude. The brace includes an elongate member of strong, rigid plastic conformed to an arm through the elbow region in a partially bent state and that is transversely curved to partially enclose the arm, and padding material mounted therein, that overlaps the edges of the stiff plastic member, for arm protection. A plurality of straps equipped with interconnect structure, such as Velcro interconnect material, are fastened to the arm brace to strap hold the brace in place on the arm.
