From previous researches, studies on the forward fall had focused on the relationship between the joint loading and position of the forearm and elbow. Previous studies also stressed the importance of energy absorption by the shoulder and elbow during the forward fall. However, the effects of different tilting angles on joint loading of the upper extremity had not been presented. This study investigated the effects of different tilting angles on joint loading of the upper extremity during fall on an outstretched hand. The absorbed energy at Ts, T1, T2 and Te were analyzed. Ten healthy young males were selected in this study. Subjects were adjusted to different trunk tilting angles of 0°, 10°, 20° and 30°with a custom-made suspension system with an outstretched hand of 5 cm height above the ground. The expert vision motion system with 6 CCD cameras and one force plate were used to collect kinetics and kinematics data. The results showed that shoulder would absorb the most impact energy and followed by wrist and elbow. The time period at T2 to Te absorbed more energy in every joint.
