Therapy device for performing a sustained, passive and/or actively assisted motion of the fingers and thumb of the hand of a patient, comprising: - one or more finger motion rails, which are designed to perform a sustained, passive and/or actively assisted motion of selected fingers of the hand of a patient, - and a support, which has an upper shell to which the one or more finger motion rails for each selected finger are connected, which finger motion rails are each in control engagement with a control system, wherein - the finger motion rails, which each consist of - mechanical components for moving the finger, which comprise at least motion kinematics, and - a motion drive, for passive and/or actively assisted motion of the respective finger are arranged adjustably and lockably on the upper shell; - wherein the motion kinematics of the finger motion rail for each selected finger are connected to the upper shell, - wherein the finger motion rail in each case has the motion drive in control engagement with the control system; - and wherein the motion kinematics of the finger motion rail, which have - a carriage that moves in a rail arranged around the metacarpophalangeal joint, - and at least one pivoting lever (213, 214), are arranged laterally alongside each finger for the passive and/or actively assisted motion of the selected fingers; - wherein each motion drive provides motorized driving of - the carriage - and the at least one pivoting lever (213; 214), characterized in that the motion kinematics have at least one lever mechanism (215; 216), wherein the motion drive provides motorized driving of the at least one pivoting lever (213; 214) via the at least one lever mechanism (215; 216). - one or more finger motion rails, which are designed to perform a sustained, passive and/or actively assisted motion of selected fingers of the hand of a patient, - and a support, which has an upper shell to which the one or more finger motion rails for each selected finger are connected, which finger motion rails are each in control engagement with a control system, wherein - the finger motion rails, which each consist of - mechanical components for moving the finger, which comprise at least motion kinematics, and - a motion drive, for passive and/or actively assisted motion of the respective finger are arranged adjustably and lockably on the upper shell; - mechanical components for moving the finger, which comprise at least motion kinematics, and - a motion drive, for passive and/or actively assisted motion of the respective finger are arranged adjustably and lockably on the upper shell; - wherein the motion kinematics of the finger motion rail for each selected finger are connected to the upper shell, - wherein the finger motion rail in each case has the motion drive in control engagement with the control system; - and wherein the motion kinematics of the finger motion rail, which have - a carriage that moves in a rail arranged around the metacarpophalangeal joint, - and at least one pivoting lever (213, 214), are arranged laterally alongside each finger for the passive and/or actively assisted motion of the selected fingers; - a carriage that moves in a rail arranged around the metacarpophalangeal joint, - and at least one pivoting lever (213, 214), are arranged laterally alongside each finger for the passive and/or actively assisted motion of the selected fingers; - wherein each motion drive provides motorized driving of - the carriage - and the at least one pivoting lever (213; 214), - the carriage - and the at least one pivoting lever (213; 214),
