不同时期生物反馈联合低频电刺激疗法对初产妇产后盆底功能障碍性疾病的影响

Effect of biofeedback combined with low-frequency electrical stimulation in different periods on postpartum pelvic floor dysfunction in primipara

目的观察不同时期生物反馈联合低频电刺激疗法治疗初产妇产后盆底功能障碍性疾病的疗效。方法选取盆底功能障碍初产妇300例,随机分为对照组和研究组,每组150例。对照组产后6个月开始进行生物反馈联合低频电刺激治疗,研究组产后42 d即进行上述治疗。疗程结束后比较两组患者的盆底肌Ⅰ、Ⅱ类纤维肌电压;随访6个月,比较两组患者子宫脱垂、尿失禁的发生率及其生活质量。结果治疗前,两组患者盆底肌Ⅰ、Ⅱ类纤维肌电压及生活质量差异无统计学意义(P>0.05);治疗后,两组的盆底肌Ⅰ、Ⅱ类纤维肌电压及生活质量评分均高于治疗前,且研究组更显著(P<0.01);研究组的子宫脱垂和尿失禁发生率均低于对照组,差异有统计学意义(P<0.05或0.01)。结论产后42 d即开展生物反馈联合低频电刺激治疗可显著提升初产妇盆底肌肉神经功能和肌力,有利于减少症状的发生,提升患者的生活质量。

Objective To observe the therapeutic effect of biofeedback combined with low-frequency electrical stimulation in different periods on postpartum pelvic floor dysfunction in primipara.Methods A total of 300 primiparas with pelvic floor dysfunction were selected and randomly divided into the Study Group and the Control Group,150 cases in each group.The Control Group was treated with biofeedback combined with low-frequency electrical stimulation 6 months after delivery while the Study Group received the above treatment 42 days after delivery.At the end of the course of treatment,the two groups were compared in terms of their TypeⅠandⅡfibromuscular voltage of pelvic floor muscle;and after six months of follow-up,the two groups were compared in terms of the incidence of metroptosis and uroclepsia as well as the quality of life.Results Before the treatment,there were no significant differences in TypeⅠandⅡfibromuscular voltage of pelvic floor muscle and quality of life between the two groups(P>0.05);after the treatment,both groups had the TypeⅠandⅡfibromuscular voltage of pelvic floor muscle and quality of life score higher than those before the treatment,and the Study Group showed a more significant increase(P<0.01);and the Study Group had the incidence of metroptosis and uroclepsia significantly lower than the Control Group,and the difference was statistically significant(P<0.05 or 0.01).Conclusion The treatment with biofeedback combined with low-frequency electrical stimulation at postpartum 42 d can significantly improve the nerve function and muscle strength of pelvic floor muscle of primipara,and is conducive to the reduction of the incidence of symptoms and the improvement of the quality of life.
