In the physical therapy field, physicians encounter some patients who cannot maintain their posture in the standing position because of decreased activity of the lumbar spine. In such cases, forward weight shifting in the standing position may be performed. The purpose of this study was to examine postural changes and muscle activity during forward weight shifting while standing. We observed that during forward weight shifting, the activity of the multifidus muscle (L4/S1) increased from the initial stage, with the anteversion of the lower legs and pelvis. To maintain the posture of the lower lumbar spine, the muscle activity of multifidus (S1) must start prior to that of multifidus (L4).
