Cadaveric lumbar motion segments (consisting of two vertebrae and the intervening disc and ligaments) were loaded to simulate forward bending movements in life, and the flexion angle at the elastic limit was measured. These flexion angles were then compared with flexion angles obtained from X-rays of healthy volunteers in the erect standing and fully flexed positions. The comparison showed that, when people adopt the static, fully flexed posture, the osteoligamentous lumbar spine is flexed about 10° short of its elastic limit.
尸体腰椎运动节段（由两个椎体以及其间的椎间盘和韧带组成）被加载以模拟生活中的前屈运动，并测量弹性极限时的屈曲角度。然后将这些屈曲角度与健康志愿者在直立站立和完全屈曲位置的X射线获得的屈曲角度进行比较。比较结果表明，当人们采取静态、完全屈曲姿势时，骨韧带性腰椎的屈曲角度比其弹性极限短约10°。
