目的：一些随机对照试验证明盆底肌肉训练治疗压力性尿失禁是有效的。本研究的目的是比较有反应者和无反应者的肌肉力量增加和最大力量与盆底肌肉训练的差异。材料和方法：52例经尿动力学检查证实为压力性尿失禁的女性，参加了为期6个月的盆底肌肉训练的随机对照试验，平均年龄45.4岁(24-)。根据五个影响变量的组合，这些女性被分为有反应和无反应两类，这些变量包括尿动力学测量、标准化膀胱容量的PAD测试和自我报告。用连接到光纤微尖换能器(CAMTech AS，Sandvika，挪威)的阴道气囊测量盆底肌肉力量。结果：烤瓷修复体最大强度的改善与渗漏指数的改善呈正相关(r=0.34，P<；0.01)，PAD试验测定的渗漏减少(r=0.23，P=0.05)。52名女性的总样本包括21名应答者、18名无法分类的应答者和13名非应答者。应答者和无应答者训练后的最大力量分别为24.0cmH2O(95%CI：18.1-29.9)和12.7cmH2O(95%CI：6.8-18.6P<；0.001)，强度增加；14.8cmH2O(95%CI：8.9-20.7)和5.0cmH2O(95%CI：2.612.6)(P=0.03)。结论：盆底肌力增加与最大肌力、压力性尿失禁改善呈正相关。
Aims: 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. Materials and Methods: 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). Results: 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% Cl: 8.9-20.7) versus 5.0 cm H2O (95% Cl: 2.6-12.6), respectively (P = 0.03). Conclusions: There was a positive relation between both pelvic floor muscle strength increase and maximal strength, and improvement of stress urinary incontinence.
