Abstract

A lower limb prosthesis has a pelvic attachment, thigh (5) and shin components interconnected by a knee joint, and, interconnecting the pelvic attachment and the thigh component, a hip joint (4) which includes an adaptive hip flexion drive mechanism (8, 9). This mechanism is arranged to apply a dynamically variable flexion moment to the hip joint, and comprises an adaptive resilient energy storing device which stores energy during hip extension and returns the stored energy during subsequent flexion. The energy storage device comprises an electronically controlled piston and cylinder assembly, the piston rod of which is, itself, a telescopic mechanism for limiting the duration of the swing phase.
