Abstract
An improved lower leg prosthesis is disclosed for providing an improved performance, including improved stability and improved multi-axial compliance. The prosthesis includes a two-part lower foot plate, incorporating a forefoot plate and a heel plate, and an upper foot plate that is attached to the forefoot and heel plates by a two-part intermediate elastomeric layer. Forming the lower foot plate and the elastomeric layer each in two parts ensures that the forefoot plate and heel plate function substantially independently of each other, which leads to substantially improved cushioning at heel strike and to improved stability throughout the gait cycle.
