Abstract
Abstract Apparatus for applying a generally dorsally directed force to the palm of a person's hand includes an upper structural support which is structured to be secured in generally overlying relationship with respect to the dorsal region of the metacarpals. The upper support has a base structured to be in contact with the hand and support for straps. A palmar compression pad is structured to be in contact with the palm of the hand with the strap or straps being placed in tension to thereby resist undesired movement of the flexor tendon and thereby reduce median nerve compression in the carpal tunnel. In a first embodiment the upper support will have a base, a pair of apertured towers secured to the base through which a strap or straps may pass and a suitable structure for fastening the strap or straps to the upper support. The strap or straps will preferably be adjustably and removably securable to regions adjacent the ends of the palmar compression pad. A bridge may be provided between the upper support towers for facilitating securing the strap or straps thereto. In another embodiment of the invention, the bridge and towers are eliminated. The palmar compression pad is generally rigid and has a pair of generally upwardly extending legs through which one or more straps pass with the upper support secured to the strap. The strap is placed in tension in order to provide the desired dorsally directed force to the palm of the user's hand. Related methods are provided.
