Variations of the different body parts (left side) for one walking cycle with relative velocity v r =1 . Variations of the right human body parts are obtained by a phase displacement of half a cycle. (a) Body displacements. (b) Pelvic angular variations. (c) Angular variations of the left shoulder, elbow, and thorax. (d) Angular variations of the left hip, knee, and ankle.
