The invention relates to a method for controlling a prosthesis or orthosis of a lower limb, comprising an upper part (10) and a lower part (20) which is connected to the upper part (10) by means of a knee joint (1) and which is mounted so as to be pivotable about a joint axis (15) relative to the upper part (10), according to the invention, an adjustable resistance device (40) is arranged between the upper part (10) and the lower part (20), by means of which resistance device the buckling resistance (Rf) is changed on the basis of sensor data, an axial force (FA) acting on the lower part being detected by at least one sensor (54) and used as a basis for changing the buckling resistance (Rf), in the case of a reduced axial force (FA) and/or a nearly vertical position of the leg tendon (70) and/or an extended knee joint (1), the bending resistance (Rf) is reduced, in which the bending resistance (Rf) is reduced when a knee bending is not detected within a certain time interval and/or the knee joint (1) and/or t
