The purpose of this study was to describe how clinical pelvic-floor muscle (PFM) strength (force-generating capacity) is related to patient characteristics, lower urinary tract symptoms, and fecal incontinence symptoms.
Data were obtained from 643 women who were participating in a randomized surgical trial for treatment of stress urinary incontinence.
Patient demographic variables, baseline urinary and fecal incontinence symptom questionnaires, urodynamic data and urinary diary data, pad test results, and standardized assessment of pelvic organ support were compared with PFM strength as described by the Brink scoring system. Bivariate analysis of factors associated with the Brink scale score was done using analysis of variance and linear regression. Multivariate analysis included patient variables that were significant on bivariate analysis.
The mean Brink scale score was 9 (SD=2) and did not vary widely in this large, but highly select, patient sample. We found a weak, but statistically strong, relationship between age and Brink score. Brink scores were not related to diary and pad test measures of incontinence severity.
Overall, PFM strength was good in this sample of women with stress incontinence. Scores tended to be similar, and it is possible that the Brink scale does not reflect real clinical differences in PFM strength.
本研究旨在描述临床盆底肌肉（PFM）力量（产生力的能力）与患者特征、下尿路症状及大便失禁症状之间的关系。
数据来自643名参与压力性尿失禁随机手术试验的女性。
将患者人口统计学变量、基线尿失禁和大便失禁症状问卷、尿动力学数据和排尿日记数据、护垫试验结果以及盆腔器官支持的标准化评估与Brink评分系统所描述的PFM力量进行比较。使用方差分析和线性回归对与Brink量表评分相关的因素进行双变量分析。多变量分析纳入了在双变量分析中具有显著性的患者变量。
Brink量表平均评分为9（标准差=2），在这个规模较大但经过高度筛选的患者样本中，评分差异不大。我们发现年龄与Brink评分之间存在微弱但在统计学上显著的关系。Brink评分与失禁严重程度的日记和护垫试验测量结果无关。
总体而言，在这个压力性尿失禁女性样本中，PFM力量良好。评分趋于相似，Brink量表有可能并未反映出PFM力量的实际临床差异。
