This study questioned whether postural sway increase in low back pain subjects was related to impaired spine mobility, and especially to a decrease in the range of motion, which was assumed to represent structural spine stiffness. Ten low back pain subjects and ten healthy control subjects performed spine flexion-extension and spine side bending tests, and standing posturographic examination in different experimental conditions. Low back pain subjects showed increased postural sway along the antero-posterior axis and reduced side bending, i.e. posturographic and range of motion parameters varied in the opposite direction. Moreover, no correlation was found between these two types of parameters. Although significant, the slight decrease in spine side bending did not seem sufficiently great to disturb the low amplitude movements that maintain postural equilibrium. Hence, it was concluded that postural sway increase in low back pain is not related to a reduced spine range of motion, but might be linked to an increase in muscular active tension, which reduces dynamic mobility capacity.
本研究探讨了腰痛患者姿势摆动增加是否与脊柱活动度受损有关，特别是与被认为代表脊柱结构僵硬的活动范围减小有关。十名腰痛患者和十名健康对照者在不同实验条件下进行了脊柱屈伸和脊柱侧屈测试以及站立姿势描记检查。腰痛患者沿前后轴的姿势摆动增加，侧屈减少，即姿势描记参数和活动范围参数呈相反变化。此外，未发现这两种类型参数之间存在相关性。尽管脊柱侧屈有轻微下降，但似乎不足以干扰维持姿势平衡的低幅度运动。因此，得出的结论是，腰痛患者姿势摆动增加与脊柱活动范围减小无关，但可能与肌肉主动张力增加有关，这会降低动态活动能力。
