Abstract
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.
