Biomechanic and Energetic Effects of a Quasi-Passive Artificial Gastrocnemius on Transtibial Amputee Gait

Figure 1

Joint mechanism of the quasi-passive artificial gastrocnemius. The exploded view of the joint design (b) is shown along with a rendering of the assembled joint without the cover (a). The Housing was attached to the proximal part of the orthosis, and the Rotating Clutch Ring attached to the distal part of the orthosis.
