Transverse Plane Rotations of the Pelvis and Lower Extremity During Walking In the animation that I created below, the transverse plane rotations of the pelvis and lower extremity are illustrated. Please note that the transverse plane rotations within the pelvis correspond to the motions of one leg swinging forwads and the opposite limb in stance phase moving backwards relative to the pelvis. These transverse plane rotations of the pelvis in the bipedal human are thought to not only increase the
