Abstract
A leg prosthesis having an artificial knee joint with swing phase control and recoil break comprises a damping member acting upon the knee joint, detectors for detecting force, knee angle and acceleration and a control unit for controlling the dampening degree of the damping member on the basis of the detected values. The damping characteristics of the damping member are varied in dependence on control signals produced by the control unit on the basis of a viscosity change of the magneto-rheological liquid.
