Figure 3.
a. (Adapted from Reference 50, with permission.) The convex pattern of the moment of resistance to deflection during the dorsiflexion period for prosthetic mechanisms of bending class, such as the SACH foot. Figure 3b. The convex pattern of the moment of resistance to deflection during the dorsiflexion period for the uniaxial foot. Figure 3c. The convex pattern of the moment of resistance to deflection during the dorsiflexion seen in the biological ankle and in the cam-rolling mechanism of the RJ foot.
