Healthy 30 persons, 15 males and 15 females, were subjected to study the movement of the hip-joint, pelvis and trunk during standing trunk flexion using a digital camera. The movement of the hip joint linearly increased in correlation with the scale of standing trunk flexion. The trunk movement was exponentially inclined and then remained stable with the trunk flexion of the finger-floor distance less than 10 cm. Thus, while the anterior trunk flexion was much more involved at the initial stage of standing trunk flexion, the movement of the hip joint played more important role at a later half of flexion. In females the range of motion of the hip joint played a greater role than in males. Standing trunk flexion was considered to be highly influenced by the anterior inclination of hip joints or pelvis.
