Abstract

A self contained electronically controlled brace system has been designed to provide complete stability in stance phase, yet permitting unhampered knee movements in swing phase. A wrap spring clutch was selected to control knee flexion consisting of a pair of unmatched diameter clutch arbors, a close-wound helical spring, and a control collar. Optimization results showed that the arbor length reached minimum at a radial interference of 0.127 mm. Motion data indicated that the activated, or free, brace allowed nearly normal knee flexion during swing while providing flexion restraint during stance.
