Abstract |
The study examined effects of lumbar and pelvic belts on the change of lumbosacral angle (LSA) and back muscle activity in postures of standing, erect sitting and slump sitting. Eighteen healthy male subjects participated in this study. Though no significant belt effect was identified on the back muscle EMG, the radiographic data revealed an interactive effect of postures and belts on the change of LSA. In standing, the belts increased LSA. In erect sitting, the lumbar belt had no effect but the pelvic belt decreased LSA. While sitting slump with a trunk flexion of 15°, both belts increased LSA by restricting the movement of the pelvis. Belt effect on LSA was accompanied with a change of pelvic angle. |
