Abstract (en)
[origin: WO9415571A1] The leg movement rail is used for the repetitive, especially passive, movement of the knee and hip joints in orthopaedics. It consists essentially of a base (1), a thigh-side rod (2) which is secured at one end (21) by means of a rotary joint (22) to the base (1), a shin-side L-shaped rod (3), the shorter shank (31) of which is secured to the base (1) by a rotary joint (32) arranged to tbe movable along the base (1) and an articulated mechanism (10) connecting the other end (22) of the rod and the longer shank (33) of the rod (3). The articulated mechanism (10) consists of a jointed polygon (7) which, during a to and fro movement of the shorter shank (31) of the rod (3) secured to rotate on the base (1), generates a curved path (13) around the virtual axis of rotation (12) of the hip which corresponds to the idealised, curved path (13') of the knee joint of the body concerned about the axis of rotation (12') of the patient's hip. A further advantage of the leg movement rail lies in the fact that there is no need for any technical right/left conversion for the other limb.
