Comparison of walking mechanics in chimpanzees and humans.

GRF vectors and joint torque for humans and chimpanzees. Figures show joint positions at 50% stance (forelimb and hindlimb shown separately for quadrupedal chimpanzees). Positive torque values indicate flexion, whereas negative values indicate extension. Note the large hip flexion moments in chimpanzees relative to humans. Horizontal dashed lines indicate zero joint torque.
