Several randomized controlled trials have demonstrated that pelvic floor muscle training is effective to treat stress urinary incontinence. The aim of the present study was to compare muscle strength increase and maximal strength in responders and non-responders to pelvic floor muscle training.
Fifty-two women with urodynamically proven stress incontinence who had participated in a six months randomized controlled trial on pelvic floor muscle training, mean age 45.4 years (range 24-64), participated in the study. The women were classified as responders and non-responders based on a combination of five effect variables covering urodynamic measurement, pad test with standardized bladder volume, and self-reports. Pelvic floor muscle strength was measured with a vaginal balloon connected to a fiber optic micro tip transducer (Camtech AS, Sandvika, Norway).
There was a positive correlation between improvement in PFM maximal strength and improvement measured by leakage index (r = 0.34, P < 0.01), and reduction in urinary leakage measured by the pad test (r = 0.23, P = 0.05). The total sample of 52 women comprised 21 responders, 18 unclassifiable, and 13 non-responders. There was a statistically significant difference in maximal strength after the training period between responders and non-responders; 24.0 cm H2O (95% CI:18.1-29.9) versus 12.7 cm H2O (95% CI: 6.8-18.6) P < 0.001), and strength increase; 14.8 cm H2O (95% CI: 8.9-20.7) versus 5.0 cm H2O (95% CI: 2.6-12.6), respectively (P = 0.03).
There was a positive relation between both pelvic floor muscle strength increase and maximal strength, and improvement of stress urinary incontinence.
多项随机对照试验已证明盆底肌肉训练对治疗压力性尿失禁有效。本研究的目的是比较盆底肌肉训练的反应者和无反应者的肌肉力量增加情况和最大力量。
52名经尿动力学证实患有压力性尿失禁的女性参与了本研究，她们参加了一项为期6个月的盆底肌肉训练随机对照试验，平均年龄45.4岁（范围24 - 64岁）。根据涵盖尿动力学测量、标准化膀胱容量的尿垫试验和自我报告的五个效应变量的组合，将这些女性分为反应者和无反应者。使用连接到光纤微尖端换能器（挪威桑德维卡的Camtech AS公司）的阴道球囊测量盆底肌肉力量。
盆底肌肉最大力量的改善与通过漏尿指数测量的改善之间存在正相关（r = 0.34，P < 0.01），以及通过尿垫试验测量的尿漏减少之间存在正相关（r = 0.23，P = 0.05）。52名女性的总样本包括21名反应者、18名无法分类者和13名无反应者。训练期后，反应者和无反应者在最大力量方面存在统计学显著差异；分别为24.0 cm H2O（95% CI：18.1 - 29.9）和12.7 cm H2O（95% CI：6.8 - 18.6），P < 0.001），以及力量增加；分别为14.8 cm H2O（95% CI：8.9 - 20.7）和5.0 cm H2O（95% CI：2.6 - 12.6），（P = 0.03）。
盆底肌肉力量增加和最大力量与压力性尿失禁的改善之间均存在正相关。
