ABSTRACT:
A method is provided for verifying the adjustment of a leg prosthesis. The leg prosthesis includes a prosthetic knee joint pivotally connected to an upper connection and a lower leg shaft. The upper connection fixes the leg prosthesis on a user of the leg prosthesis and the lower leg shaft fastens to a prosthetic foot. The upper connection is displaceable in relation to a joint axis of the prosthetic knee joint. The method includes measuring a knee moment and an axial force by means of sensors when leg prosthesis is being used; calculating a resultant force vector using the knee moment and the axial force; calculating a normal distance relative to the joint axis and the position of the resultant force vector in relation to the joint axis; and verifying a position of the resultant force vector relative to the joint axis in the sagittal plane.
