Abstract

L'invention concerne un rail de déplacement de doigt (2) pour un appareil de thérapie permettant la réalisation d'un mouvement continu, passif et/ou assisté de manière active des doigts et du pouce de la main (3) d'un patient. L'appareil comprend une coque supérieure (10) à laquelle sont reliés des dispositifs cinématiques de mouvement (21) d'un rail de mouvement de doigt (2) pour chaque doigt sélectionné, qui comportent chacun un entraînement de mouvement 22) en liaison de commande avec un dispositif de commande (14). Le rail se caractérise par le fait que les dispositifs de cinématique de mouvement (21) du rail de mouvement de doigt (2), lesquels comprennent un coulisseau (211) qui se déplace dans un rail (212) agencé autour de l'articulation de base du doigt (31), et au moins un levier pivotant (213, 214), sont agencés latéralement à côté du doigt respectif pour le déplacement passif et/ou assisté de manière active des doigts sélectionnés. Ceci permet de manière avantageuse de fournir pour chaque doigt sélectionné un rail de mouvement de doigt (2) propre présentant des dispositifs de cinématique de mouvement (21), qui est agencé à côté du doigt à traiter et qui permet à chaque doigt sélectionné de se plier et/ou de s'étirer librement.
