Comparative Biomechanics of Gait in Lower Limb Amputees

Quick fact

Amputee gait often requires up to 30–50% more metabolic energy than normal walking, because the loss of ankle push-off and the added mass of a prosthesis force the body to use inefficient compensatory movements like hip hiking and vaulting.
