  • the device in particular the individual finger movement rails, must be adapted to the respective anatomy, that is to say to the hand size and / or the individual finger dimensions, before training begins.
  • the individual finger movement rails are usually attached manually to the upper shell or holder of the respective therapy device in the optimal position for the respective user, the finger movement rails must then be released manually after a training session and then again manually for the next user be reattached. This procedure is time-consuming and, in everyday clinical practice, disadvantageously shortens the training time available for the respective user with the therapy device.

Abstract

La présente invention concerne un dispositif de réglage de la longueur (3) d'un rail de mouvement de doigt (2) d'un appareil de thérapie (1) pour effectuer un mouvement continu, passif et/ou activement assisté d'un doigt et/ou du pouce d'une main ; un rail de mouvement de doigt (2) pourvu d'un tel dispositif de réglage de la longueur (3) et un appareil de thérapie (1) correspondant comprenant au moins un tel rail de mouvement de doigt (2). Elle concerne également un procédé de réglage de la longueur d'un rail de mouvement de doigt (2) sur un tel appareil de thérapie (1). Selon l'invention, le dispositif de réglage de la longueur (3) ou le procédé de réglage de la longueur permet, avantageusement, de déplacer automatiquement un rail de mouvement de doigt (2) le long du rail de réglage (30) à l'aide de l'entraînement (10) déjà présent pour le rail de mouvement de doigt (2) sur un appareil de thérapie (1) et de le fixer à une position souhaitée - en fonction de la longueur des doigts ou de la taille/longueur de la main de l'utilisateur - sur le rail de réglage (30) et donc sur l'appareil de thérapie (1), afin de pouvoir ensuite effectuer un mouvement continu, passif et/ou activement assisté d'un doigt et/ou du pouce d'une main dans une position stable. Le réglage manuel, qui prend beaucoup de temps, est ainsi avantageusement évité.
