The teaching playback swing-phase-controlled above-knee prosthesis is capable of automatically controlling the speed of swing motion of the leg frame according to the actual walking speed of the prosthesis wearer.

A teaching playback swing-phase-controlled above-knee prosthesis has a thigh frame, a leg frame, an air cylinder interconnecting the thigh and leg frames and provided with adjusting means for adjusting the degree of opening the valve of the air cylinder to a plurality of degrees respectively for a plurality of walking speeds selected during trial walking. A mode selecting switch has positions respectively for setting degrees of opening of the valve of the air cylinder in a teaching mode and for a playback mode in which one of the degrees of opening is selected according to an actual walking speed. An opening detector detects the degree of opening of the valve of the air cylinder. An opening storage device for stores a plurality of set degrees of opening of the valve of the air cylinder. A phase detector detects swing phases and stance phases, walking speed detector determines an actual walking speed, and control unit adjusts the degree of opening of the valve of the air cylinder to one of the set degrees of opening corresponding to the actual walking speed. The teaching playback swing-phase-controlled above-knee prosthesis is capable of automatically controlling the speed of swing motion of the leg frame according to the actual walking speed of the prosthesis wearer.
