A finger motion rail for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a patient, comprising: - a means, arranged laterally alongside the respective finger and/or thumb, for flexion of a metacarpophalangeal joint; - a mechanism, arranged laterally alongside the respective finger and/or thumb, for flexion of a proximal interphalangeal joint and/or a distal interphalangeal joint; - and a first connection lever for connecting the mechanism to the means for flexion of a metacarpophalangeal joint, - in which said mechanism comprises at least one pivot lever (2201; 2202), operatively connected to the first connection lever, for interaction with the proximal interphalangeal joint and/or with the distal interphalangeal joint; characterized in that the means for flexion of a metacarpophalangeal joint is designed as a multi-joint hinge, - in which the means for flexion of a metacarpophalangeal joint has a first lever for rigid connection to a holder of a therapeutic device for carrying out a continuous, passive and/or actively assisted movement of the fingers and/or the thumb of the hand of a patient; - in which a second lever is rotatably connected to the first lever via a first joint, in which the second lever comprises at least one engagement joint for connection to a movement drive; - in which a third lever is rotatably connected to the first lever via a second joint; - in which the second lever via a fourth joint and the third lever via a third joint are rotatably connected to each other via a fourth lever; - in which the third lever is rotatably connected to a fifth lever via a fifth joint; - and in which the fourth lever via a seventh joint and the fifth lever via a sixth joint are rotatably connected to each other via the connection lever; and that the means for flexion of a metacarpophalangeal joint, in addition to the connection via a first connection lever, via at least one second connection lever and at least one connection joint (2114; 2115), is operatively connected to the mechanism for flexion of a proximal interphalangeal joint and/or a distal interphalangeal joint. - a means, arranged laterally alongside the respective finger and/or thumb, for flexion of a metacarpophalangeal joint;
