摘要
背景:妊娠相关骨盆痛患者常常有不同程度的行走功能障碍,但具体发病机制尚未阐明。目的:通过了解妊娠相关骨盆痛患者步行速度、步态与胸廓、骨盆和腰椎的运动协调的变化,探讨妊娠相关骨盆痛运动病理机制。方法:比较12名健康孕妇和12名患有妊娠相关骨盆痛孕妇的步态运动,计算其胸廓、骨盆和腰椎在水平面上节段性旋转的幅度、各个节段旋转的时间差和节段间的相对相以及脊柱整体旋转的幅度。结果与结论:妊娠相关骨盆痛患者的步行速度较对照组慢,并且与运动恐惧感呈负性相关。患者胸廓、骨盆和腰椎的旋转幅度较大,而且有较大的个体间差异。脊柱的旋转在两组间没有差别。患者快速步行时胸廓旋转的峰值出现在步态周期的早期而相对相却较小,也许这可以避免骶髂关节和脊柱过度旋转的转矩。
BACKGROUND：Walking is often impaired in pregnancy-related pelvic girdle pain（PPP）,but the precise pathogenesis remains poorly understood.OBJECTIVE：To better understand the walking velocity,gait and changes in movement coordination in patients with PPP and to explore its underlying mechanism of movement pathology.METHODS：The gait kinematics of 12 healthy pregnant women and 12 pregnant women with PPP were compared,focusing on the amplitudes of transverse pelvic,lumbar,and thoracic segmental rotations,the timing and relative phase of these rotations,and the amplitude of spinal rotations.RESULTS AND CONCLUSION：The walking velocity of pregnant women with PPP was lower than that of the controls,and negatively correlated with fear of movement.While patients＇ amplitudes were larger in transverse pelvic,lumbar,and thoracic segmental rotations,and there were large inter-individual differences.The spinal rotations did not differ between groups.In the patients,peak thorax rotation occurred earlier in the stride cycle at higher velocities,and relative phase was lower,probably to avoid excessive rotational torque in the sacroiliac joints and the spine.
