&L Engineering, Tustin, CA) were attached bilaterally on the pelvis, thigh, shank, and foot of each participant for motion capture (Table  2 ). Calibration markers were utilized to estimate joint centers from a static calibration trial and were removed prior to walking trials. Measurement of segment motion was

and the pelvis in that posture. In the late 19th century, Vierordt ( 1864 ) was likely the first to quantitatively measure postural sway during standing; he employed a device that measured the sway of the head. Neither Borelli nor Vierordt measured the forces on the feet, although they acknowledged

clinical setting along with gait testing by clinicians. This is particularly important because turning is a complex motor task that involves multisegmental rotation and temporal coordination of head, trunk, and pelvis while maintaining postural stability of the whole body. Previous research reported that

In children, jump height increases with age, standing height, and mass ( 2 ). To assess whether differences in jump height were

positive power. Alternatively, pelvis position, rather than trunk position, is also suggested to affect age-related differences in hip position, 11 , 20 and in effect, hip kinetics, and has a more direct effect on hip angle than trunk position. Manipulating the pelvis angle during gait is challenging, but
