The present invention provides an orthotic appliance for the carpus of a human hand for the treatment of a carpal tunnel syndrome condition using co-dynamic, rather than traditional static or dynamic, techniques. The appliance may apply a dorsally-directed force to the region of the pisiform bone (23) in the neutral carpal position of a human hand upon co-contraction of the hand and up to 8 pounds dorsally-directed during arc of motion in carpal flexion, as the wrist and hand is encouraged to actively move in all planes of motion without restricting arc of motion or negatively affecting the normal activities of daily living. The appliance may comprise a biasing structure for applying the dorsally-directed force and a base structure for maintaining the biasing structure in its proper configuration during normal hand motion.

L'invention concerne un appareil orthétique destiné au carpe d'une main humaine, utilisé dans le traitement du syndrome du canal carpien par la mise en oeuvre de techniques co-dynamiques plutôt que statiques ou dynamiques classiques. Cet appareil peut appliquer une force dirigée dorsale sur la zone de l'os pisiforme (23) dans une position carpienne neutre d'une main humaine lors d'une co-contraction de la main, et une force allant jusqu'à 8 livres, dirigée dorsale, lors d'un mouvement en arc de flexion carpienne, le poignet et la main pouvant bouger activement dans tous les plans de mouvement, sans restreindre l'arc de mouvements ni affecter les activités de la vie quotidienne. L'appareil selon l'invention peut comprendre une structure de polarisation destinée à appliquer la force dirigée dorsale, et une structure de base destinée à maintenir la structure de polarisation dans sa configuration propre lors d'un mouvement normal de la main.
