Figure 2:
Schematic representation of the experimental protocol. A nominal stiffness (NS) condition was chosen according to body weight, used for prosthetic alignment, and tested at five walking speeds (0.7, 0.9, 1.1, 1.3, 1.5 m·s−1). Then hindfoot and forefoot keels were changed individually to alter the stiffness of each component (CH, SH, CF, SF conditions), and tested at the same five speeds.
