The effect of sitting posture on the loads at cervico-thoracic and lumbosacral joints

摘要: Background The sitting in an awkward posture for a prolonged time may lead to spinal or musculoskeletal disease. It is important investigate the joint loads at spine while sitting. Objective purpose of this study was moment and antero-posterior (AP) reaction force cervico-thoracic lumbosacral various postures. Methods Twenty healthy males participated study. Six postures were defined from three curvatures (slump, flat, lordosis) two arm (arms-on-chest arms-forward). Kinematic kinetic data measured six which AP calculated by inverse dynamics. Results In joint, greater slump than flat lordosis (p 0.86) those correlated trunk flexion angle (r> 0.77). posture, moments close over extreme daily life such as sit-to-stand walking. Consequently, if continued long time, it cause pain diseases joints. Conclusions results indicated that would be better Also, keeping arms body desirable reduce loads.
