Abstract

Most of the energy needed for ambulation is generated during the double support phase of walking. Knee flexion during push-off is crucial to maintain the walking velocity. Since users of an above-knee prosthesis have to stabilize the knee with the hip muscles, and regular knee mechanisms are not stable during flexion, this may cost a large effort. This paper deals with experimental findings of walking with different types of knees. The results indicate that for walking with a more stable knee, the symmetry increases and the net hip moments of force, required to stabilize the knee, reduce. The mechanical work however, performed at the hip joint at the prosthetic side, remains about equal
