The purpose of this research was to determine the effect of pelvic muscle exercise (PME) on stress urinary incontinence in middle-aged and elderly women. The protocol required 16 weeks of exercise three times per week, for a total of 48 sessions. Measures were taken at baseline, after a 4-week control period and after 4, 8, 12 and 16 weeks of PME, corresponding to PME levels 1, 2, 3 and 4, respectively. Urine loss was evaluated using a urinary diary and 24-hour pad test at baseline, after the control period and after PME levels 2 and 4. Pelvic muscle function was evaluated every four weeks. Sixty-five parous women 35-75 years of age (mean, 51.3) with mild to moderate stress urinary incontinence were studied. No significant changes in the outcome variables were found after the control period. The results showed significant reductions in urine loss on the 24-hour pad test (t = -4.7, P < or = .0001), and episodes of urine loss decreased from 2.6 to 1.0 between the control period and PME level 4. In addition, a significant improvement occurred in pressures developed by the pelvic muscles in response to PME (t = 6.8, P < or = .0001). Significant correlations between changes in pelvic muscle pressure and in urine loss variables were not found. Women who completed the study experienced a significant reduction in the amount of urine loss as well as a significant increase in pelvic muscle characteristics.(ABSTRACT TRUNCATED AT 250 WORDS)
本研究的目的是确定盆底肌锻炼（PME）对中老年女性压力性尿失禁的影响。该方案要求进行16周的锻炼，每周三次，共48节。在基线、4周对照期后以及PME进行4、8、12和16周后（分别对应PME水平1、2、3和4）进行测量。在基线、对照期后以及PME水平2和4后，使用排尿日记和24小时护垫试验评估尿液丢失情况。每四周评估一次盆底肌功能。对65名年龄在35 - 75岁（平均51.3岁）、患有轻度至中度压力性尿失禁的经产妇进行了研究。对照期后未发现结果变量有显著变化。结果显示，24小时护垫试验中的尿液丢失显著减少（t = -4.7，P≤0.0001），对照期与PME水平4之间，尿液丢失发作次数从2.6次降至1.0次。此外，盆底肌对PME反应产生的压力有显著改善（t = 6.8，P≤0.0001）。未发现盆底肌压力变化与尿液丢失变量之间存在显著相关性。完成研究的女性尿液丢失量显著减少，盆底肌特征也显著增加。（摘要截选至250字）
