Table 4.
Mean (SD) peak powers (W/kg) for both the prosthetic and sound limbs during the SAFE and Flex foot conditions (a indicates P<0.05 for the prosthetic type main effect, b indicates P<0.05 for the prosthetic type × limb interaction). Positive values indicate power generation, negative values indicate power absorption.
