BACKGROUND:Biostimulation feedback treatment has been widely used for female stress urinary incontinence. The treatment principle is based on the electromyographic signal measured and the combination of biofeedback technique and electrotherapy technique. OBJECTIVE:To evaluate the effect of biofeedback electrical stimulation in treatment of female stress urinary incontinence. METHODS:Thirty female patients suffering from light or moderate stress urinary incontinence received biofeedback electrical stimulation for 4-8 weeks. The stimulation parameters were 60 Hz, 20-60 mA, 12-second feedback. The patients were instructed to contract pelvic floor muscle. The peak value of surface electromyography in pelvic floor muscular 2-second-rapid-contraction, mean value of pelvic floor muscular 10-second-contraction, mean value of the pelvic floor muscular 60-second-tolerance-contraction, and the rate of urine leakage were observed before and after treatment. RESULTS AND CONCLUSION:The peak value of surface electromyography in pelvic floor muscular 2-second-rapid-contraction, mean value of pelvic floor muscular 10-second-contraction, and mean value of the pelvic floor muscular 60-second-tolerance-contraction were significantly increased after treatment, compared with before treatment (P<0.05). The rate of urine leakage was decreased obviously after treatment (P<0.05). Biofeedback electrical stimulation can significantly increase surface electromyography value of pelvic floor muscles during contraction, and is an effective treatment for female stress urinary incontinence.%背景：女性盆底肌生物反馈治疗仪已广泛应用于压力性尿失禁的治疗，其原理是利用从患者身上测量的肌电信号，并结合生物反馈技术和电疗技术来治疗女性尿失禁。 目的：探讨盆底生物刺激反馈治疗对女性压力性尿失禁的治疗效果。 方法：采用盆底生物刺激反馈治疗仪治疗30例轻、中度压力性尿失禁女性患者，治疗时间4-8周，设置刺激参数60 Hz、20-60 mA，反馈12 s指导患者收缩盆底肌肉，分析治疗前后患者盆底肌肉2 s快速收缩表面肌电最大值、盆底肌肉持续10 s收缩表面肌电平均值、盆底肌肉60 s耐受收缩表面肌电平均值变化，并观察每天漏尿次数。 结果与结论：患者治疗后盆底肌肉2 s快速收缩表面肌电最大值、盆底肌肉持续10 s收缩表面肌电平均值、盆底肌肉60 s耐受收缩表面肌电平均值等较治疗前有明显增高(P <0.05)、平均每日漏尿次数较治疗前明显减少(P<0.05)。结果证实，盆底生物刺激反馈治疗可明显增加女性轻、中度压力性尿失禁患者盆底肌肉收缩表面肌电值，疗效较好。
