Title: METHOD FOR CONTROLLING AN ARTIFICIAL ORTHOTIC OR PROSTHETIC KNEE JOINT
Abstract:
The invention relates to a method for controlling an artificial orthotic or prosthetic knee joint (2), on which a lower leg component (4, 5) is arranged and which is assigned a resistance device (3) having at least one actuator (31), by means of which the bending resistance is modified depending on sensor data that is determined during use of the orthotic or prosthetic knee joint by means of a sensor (7), wherein the absolute angle of the lower leg component (4, 5) is determined exclusively by means of at least one inertial sensor (7), the angle determined is compared with at least one threshold value, and the bending resistance is modified when the threshold value is reached.
