A finger motion rail, and a therapeutic device with a finger motion rail for carrying out a continuous, passive and/or actively assisted movement of a finger and/or thumb. A multi-joint hinge, arranged laterally alongside a finger and/or thumb, for flexion of a metacarpophalangeal joint. The multi-joint hinge is operatively connected via a first connection lever, at least one second connection lever and at least one connection joint, to a mechanism also arranged laterally alongside the respective finger and/or thumb, for flexion of a proximal interphalangeal joint and/or a distal interphalangeal joint. The finger motion rail and therapeutic device is configured as robust against the effect of compressive, tensile and torsional forces, with respect to a longitudinal axis of the finger motion rail, and it permits precise and interference-free execution of an anatomically natural, automated finger movement, for increased chance of successful therapy and the service life of the device.

Finger motion rail for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a patient, as well as a therapeutic device comprising a finger motion rail of this type

A length adjustment device for a finger motion rail of a therapeutic device, a finger motion rail having such a length adjustment device, a therapeutic device having such a finger motion rail, and a method for adjusting the length of a finger motion rail on a therapeutic device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand. The length adjustment device and adjustment method having a finger motion rail that is automatically moved along an adjustment rail by a drive on a therapeutic device and allows the finger motion rail to be fixed on the adjustment rail and therefore on the therapeutic device at a desired position in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or of a thumb of a hand in a stable position.

Length adjustment device for a finger motion rail, length-adjustable finger motion rail, and therapeutic device comprising at least one length-adjustable finger motion rail of this type, and method for length adjustment

A finger motion rail is provided for a therapy device for carrying out passive and/or actively-assisted motion of the fingers and thumb of the hand. The therapy device has an upper shell, to which a kinematic motion mechanism of the finger motion rail for each selected finger is connected, each mechanism has a motion drive that is in control engagement with a control system. The kinematic motion mechanism of the finger motion rail, which mechanism has a carriage that moves in a rail provided around the metacarpophalangeal joint and a pivoting lever, is located at the side of each finger for the passive and/or actively-assisted motion of the selected fingers. This allows an individual finger motion rail with the kinematic motion mechanism to be provided for each selected finger, the rail being located at the side of each finger, thus permitting each selected finger to bend and/or stretch without constraint.
