The invention relates to a method for controlling a prosthesis or orthosis of the lower extremity, which prosthesis or orthosis has an upper part (10) and a lower part (20), which lower part is connected to the upper part (10) by means of a knee joint (1) and is mounted for pivoting relative to the upper part (10) about a joint shaft (15); wherein an adjustable resistance device (40) is disposed between the upper part (10) and the lower part (20), by means of which resistance device a flexion resistance (Rf) is changed on the basis of sensor data; wherein an axial force (FA) acting on the lower part is sensed by at least one sensor (54) and is used as the basis for a change of the flexion resistance (Rf); wherein, in the case of decreasing axial force (FA) and/or an approximately vertical position of a leg tendon (70) and/or of an extended knee joint (1), the flexion resistance (Rf) is reduced; and wherein the flexion resistance (Rf) is increased again if, within a temporally defined interval, no knee flexion is detected and/or the knee joint (1) and/or the leg tendon (70) and/or the axial force (FA) fall below or exceed specific limit values.
