The invention relates to a method for controlling an artificial knee joint comprising an upper part (1) and a lower part (2) which are fastened to one another so as to be able to swivel about a swivel axis (4), comprising a resistance unit (6) which is arranged between the upper part (1) and the lower part (2) and has an adjusting device (7) by means of which the damping resistance can be changed, comprising a control unit (8) which is coupled to the adjusting device (7) and is at least connected to a sensor (9), the adjustment taking place on the basis of sensor data. During the swing phase at least one parameter from a group containing the knee angle (KA), the knee angle velocity (KAV), the knee angle acceleration (KAA), the lower limb angle, the lower limb velocity, the lower limb acceleration, the ankle moment (AM) and the axial force (AF) is sensed, the curve of the parameter is determined and the damping resistance is changed when, after an extreme value of the parameter is reached, the monotonic behavior of the curve of the parameter changes within the swing phase. |
