盆底肌电生物反馈疗法治疗围绝经期女性盆底功能障碍及对膀胱功能和尿流动力学影响

Efficacy of pelvic floor electromyographic biofeedback for treating perimenopausal women with pelvic floor dysfunction and its influence on the bladder function and urodynamic state of the women

目的:探究盆底肌电生物反馈疗法治疗围绝经期女性盆底功能障碍疗效及对膀胱功能和尿流动力学状态的影响。方法:选取2021年1月—2022年1月本院接诊的围绝经期女性盆底功能障碍108例,按简单随机化法分为观察组和对照组各54例,两组均常规盆底肌康复锻炼,观察组给予盆底肌电生物反馈疗法,两组均持续治疗3个月。比较治疗前、治疗3个月后盆底肌肌力、膀胱功能[初始尿意膀胱容量(FVS)、最大尿意膀胱容量(MVS)、排尿后残余尿量(PVR)]、尿流动力学[平均尿流量(AFR)、最大尿流量(MFR)、排尿时间]、生活质量[盆底功能影响评分(PFIQ-7)]的变化。结果:治疗3个月后,两组盆底肌肌力有差异(P<0.05),两组FVS、MVS、AFR、MFR均提高且观察组(234.78±12.65 ml、435.95±14.28 ml、22.78±2.15 ml/s、26.95±2.28 ml/s)均高于对照组(216.38±10.59 ml、428.86±13.40 ml、20.38±2.29 ml/s、24.86±2.40 ml/s),两组PVR、排尿时间、PFIQ-7评分均降低且观察组(5.49±2.07 ml、22.49±3.04、40.78±8.15分)低于对照组(8.52±2.25 ml、26.53±3.24 s、50.33±12.25分)(均P<0.05)。结论:盆底肌电生物反馈疗法能有效改善围绝经期女性盆底功能障碍患者膀胱功能,促进患者盆底肌肌力恢复,对预后有利。

Objective:To explore the efficacy of pelvic floor electromyographic biofeedback for treating perimenopausal women with pelvic floor dysfunction,and to study its influence on the bladder function and urodynamic state of these women.Methods:108 perimenopausal women with pelvic floor dysfunction were selected and were divided into two groups(54 cases in each group)by the simple randomization method from January 2021 to January 2022.The women in the two groups were given routine pelvic floor muscle rehabilitation exercise for 3 months continuously,and the women in the observation group were given pelvic floor electromyographic biofeedback therapy additionally.The pelvic floor muscle strength,the values of bladder function indexes,such as the first bladder volume(FVS),the maximum bladder volume(MVS),and the post-voiding residual volume(PVR),the values of urodynamics indexes,such as average urine flow rate(AFR),maximum urine flow rate(MFR),and urination time,and the quality-of-life score by Pelvic Floor Impact Questionnaire 7(PFIQ-7)of the women before treatment and after 3 months of treatment were compared between the two groups.Results:There was significant difference in the pelvic floor muscle strength of the women after 3 months of treatment between the two groups(P<0.05).The values of FVS,MVS,AFR,and MFR of the women in both groups after treatment had increased significantly,and which of the women in the observation group(234.78±12.65ml,435.95±14.28ml,22.78±2.15ml/s,and 26.95±2.28 ml/s)were significantly higher than those(216.38±10.59ml),428.86±13.40 ml,20.38±2.29 ml/s,and 24.86±2.40 ml/s)of the women in the control group.The values of PVR,urination time,and PFIQ-7 score of the women in the two groups after treatment had decreased significantly,and which(5.49±2.07ml,22.49±3.04s,and 40.78±8.15 points)of the women in the observation group were significantly lower than those(8.52±2.25ml,26.53±3.24s,and 50.33±12.25 points)of the women in the control group(all P<0.05).Conclusion:Pelvic floor electromyographic biofeedback therapy of the perimenopausal women with pelvic floor dysfunction can effectively improve their bladder function and promote their recovery of pelvic floor muscle strength,and which is beneficial to the prognosis of these women.
