Abstract

BACKGROUND

Motor control patterns are altered when women with pregnancy-related pelvic girdle pain (PGP) experience pain. In low back pain, these adaptations can persist after recovery.

OBJECTIVES

This study aimed to assess balance control in postpartum women with and without a history of PGP during pregnancy.

DESIGN

Cross-sectional study.

METHOD

Eighteen postpartum women who reported to be recovered from PGP, and twelve postpartum women without a history of PGP during pregnancy performed two clinical tests: the single leg stance and active straight leg raise test. Primary outcomes were ground reaction forces measured with a force platform.

RESULTS

Multiple linear regression analyses showed smaller lateral displacement (β = -11cm; 95%CI: 19 to -3; p = 0.008) and lower displacement velocity of the Centre of Pressure (COP) (Ratio of Geometric Means (RGM) 0.76; 95%CI: 0.59 to 0.99; p = 0.043) during single leg stance in the participants with a history of PGP compared to participants without a history of PGP. Push-off force (β = -4.8 N; 95%CI: 22.0 to 12.5; p = 0.57) and asymmetry of push-off force (RGM 1.77; 95%CI: 0.62 to 5.04; p = 0.27) did not differ between groups. During the active straight leg raise test, no differences in lateral displacement (β = 3 cm; 95%CI: 3 to 8; p = 0.30) and COP displacement velocity (RGM 1.03; 95%CI: 0.70 to 1.52; p = 0.87) were observed.

CONCLUSIONS

Although the women with a history of PGP considered themselves recovered, their balance control during single leg stance was poorer compared to those without a history of PGP. No differences were found during the active straight leg raise test.

摘要

背景

患有与妊娠相关的骨盆带疼痛（PGP）的女性在疼痛发作时运动控制模式会发生改变。在腰痛患者中，这些适应性变化在恢复后可能会持续存在。

目的

本研究旨在评估有和没有孕期PGP病史的产后女性的平衡控制能力。

设计

横断面研究。

方法

18名自称已从PGP中恢复的产后女性和12名孕期无PGP病史的产后女性进行了两项临床测试：单腿站立和主动直腿抬高试验。主要结局指标是用测力平台测量的地面反作用力。

结果

多元线性回归分析显示，与无PGP病史的参与者相比，有PGP病史的参与者在单腿站立期间的横向位移更小（β=-11cm；95%置信区间：-19至-3；p=0.008），压力中心（COP）的位移速度更低（几何均值比（RGM）为0.76；95%置信区间：0.59至0.99；p=0.043）。两组之间的蹬地力量（β=-4.8N；95%置信区间：-22.0至12.5；p=0.57）和蹬地力量不对称性（RGM为1.77；95%置信区间：0.62至5.04；p=0.27）没有差异。在主动直腿抬高试验期间，未观察到横向位移（β=3cm；95%置信区间：-3至8；p=0.30）和COP位移速度（RGM为1.03；95%置信区间：0.70至1.52；p=0.87）的差异。
