Fig. 3From: The effects of ankle stiffness on mechanics and energetics of walking with added loads: a prosthetic emulator studyTime series (normalized to percentage of prosthesis-side stride cycle) of the average angle and moment data for the ankle, knee, and hip. The moment data is normalized to the participant’s body mass (not including the weighted vest). The solid lines are the prosthetic side, and the dashed lines are the contralateral sideBack to article page
