Abstract

Supplemental Digital Content is Available in the Text. Background: Women with stress urinary incontinence (SUI) use different hip biomechanics during gait than women without SUI. Objective: To compare hip angles, moments, and temporal-spatial parameters during gait between women with and without SUI from a control to full-bladder condition. Study Design: Case-control study with a repeated-measures design. Methods: Hip angles and moments (net forces) of 19 women with SUI and 23 women without SUI were analyzed during the weight acceptance phase of the gait. Mixed-model analyses of variance were used to compare between groups (SUI, without SUI), conditions (control, full bladder), and limbs (dominant [D], nondominant [ND]). Significance: P < .05. Results: Women with SUI were older (P < .001), more active (P = .022), produced more offspring (P < .001), used lesser adduction (P = .035; D-limb only), and minimum (P = .01) and peak flexion angles (P = .01), compared with women without SUI. Hip angles (internal rotation [IR]: ND > D, P < .001; external rotation [ER]: D > ND, P = .001), and moments (IR: ND < D, P = .001) differed between limbs. For ER moments, post hoc testing revealed that ND > D were found for women without SUI (P < .001, both conditions) and women with SUI during the control condition only (P = .001). From the control to full-bladder condition, ER angles decreased (P = .012), abduction moments increased (without SUI only; P = .027), extension moments increased (P = .003; D-limb only), step time increased (P = .006), and cadence decreased (P = .007). Conclusions: Women with SUI did not use different hip moments but used different hip positions during gait compared with women without SUI. Women with and without SUI altered force generation differently in response to bladder stress. A Video Abstract for this article is available at http://links.lww.com/JWHPT/A41.

有和没有自我报告压力性尿失禁的女性在饮用16盎司水之前和之后走路不同

文本中提供了补充数字内容。背景：患有压力性尿失禁（SUI）的女性在步态中使用的髋关节生物力学与未患有SUI的女性不同。目的：比较有和没有SUI的女性从对照状态到膀胱充盈状态步态中的髋关节角度、力矩和时空参数。研究设计：采用重复测量设计的病例对照研究。方法：分析19名SUI患者和23名无SUI患者在步态重量接受阶段的髋关节角度和力矩（净力）。混合模型方差分析用于比较各组（SUI、无SUI）、条件（对照组、膀胱充盈）和四肢（显性[D]、非显性[ND]）。显著性：P＜0.05。结果：与无SUI的女性相比，有SUI的妇女年龄更大（P＜0.001），更活跃（P＝.022），生育更多的后代（P＜.001），内收较少（P＝.035；仅D肢体），最小（P＝.01）和峰值屈曲角（P＝0.01）。髋关节角度（内旋[IR]:ND>D，P<.001；外旋[ER]:D>ND，P=.001）和力矩（IR:NDD。从对照到膀胱充盈状态，ER角度减少（P=.012），外展力矩增加（仅无SUI；P=.027），伸展力矩增加（P=.003；仅D肢体），步进时间增加（P=.066），结论：与无SUI的女性相比，有SUI的妇女在步态中没有使用不同的髋关节力矩，而是使用不同的臀部位置。有和没有SUI的女性对膀胱压力的反应会改变力量的产生。本文的视频摘要可在http://links.lww.com/JWHPT/A41.
