The development of artificial limbs for lower limbs.

This project represents a continuous effort of Mauch Laboratories toward the improvement of artificial limbs, particularly for the lower limbs. Work on five items has been underway : A semivoluntary Swing and Stance Control knee mechanism (S-N-S System), an automatically controlled Tri-axial Ankle mechanism, a fully Voluntarily Actuated Swing and Stance Control knee mechanism, a mechanical low-cost version of the S-N-S System for short-term use and for geriatrics, and a novel cosmetic cover for above-knee prostheses and for a tri-axial ankle mechanism .
