生物反馈电刺激对产后压力性尿失禁患者盆底表面肌电信号及尿动力学的影响

The effect of biofeedback electrical stimulation on the surface electromyography of pelvic floor and urodynamics in patients with postpartum stress urinary incontinence

目的探讨生物反馈电刺激(biofeedback electrical stimulation,BES)对产后压力性尿失禁(stress urinary incontinence,SUI)患者盆底表面肌电信号及尿动力学的影响。方法选择2018年3~12月我院妇科门诊收治的SUI患者98例,根据就诊时间分为对照组(2018年3~7月)46例和试验组(2018年8~12月)52例。对照组给予盆底肌肉训练(pelvic floor muscle training,PFMT),试验组给予BES联合PFMT治疗。治疗8周后比较两组临床疗效、盆底肌肌电信号、尿动力学指标。结果试验组SUI患者有效率明显高于对照组(x2=4.887,P<0.05);肌电活力值、最大峰值、功值等肌电信号明显高于对照组(P<0.05);尿道最大闭合压力(PMUC)、功能尿道长度(LES)、尿道最大测量压(PMU)等尿动力学指标明显高于对照组(P<0.05)。结论生物反馈电刺激联合盆底肌肉训练有助于增强产后压力性尿失禁患者盆底表面肌电水平,改善尿动力学,提高临床疗效。

Objective To investigate the effect of biofeedback electrical stimulation(BES)on surface electromyography and urodynamics of patients with postpartum stress urinary incontinence(SUI).Methods Ninety-eight SUI patients from March 2018 to December 2018 were selected at gynecology clinic of our hospital.According to visit time,46 patients visited from March 2018 to July 2018 were taken as control group while 52 patients visited from August 2018 to December 2018 were taken as experimental group.The control group given pelvic floor muscle training(PFMT)and the experimental group given BES combined with PFMT therapy.After 8 weeks of treatment,clinical efficacy,surface electromyography,and urodynamics were compared between two groups.Results The effective rate in the experimental group was significantly higher than that in the control group(χ2=4.887,P<0.05).Myoelectric activity value,maximum peak value,and work value in the experimental group were significantly higher than those in the control group(P<0.05).PMUC,LES and PMU in the experimental group were significantly higher than those in the control group(P<0.05).Conclusion Biofeedback electrical stimulation combined with pelvic floor muscle training can help to enhance pelvic floor surface EMG level,and improve the urodynamics as well as improve the clinical efficacy.
