摘要:
目的 骶神经干预靶点在慢性盆腔痛(CPP)中的应用备受关注,本研究探讨骶神经磁刺激联合盆底肌康复训练治疗女性CPP的效果。 方法 选取2022年6月—2023年4月金华市妇幼保健院盆底门诊收治的女性慢性盆腔痛患者共92例,采用随机数字表法分为对照组和研究组,各46例。对照组给予肌筋膜手法联合生物反馈的盆底肌康复训练,研究组给予骶神经磁刺激联合盆底肌康复训练。比较2组治疗前后改良牛津肌力分级法(MOS)、盆底肌压痛检查、盆底表面肌电Glazer评估和不良反应。 结果 2组治疗后盆底肌MOS分级均较治疗前提高(均P<0.05),盆底肌筋膜扳机点(MTrP)的视觉模拟疼痛评分(VAS)均较治疗前明显降低(均P<0.05),且研究组治疗后盆底肌MOS分级、VAS评分[(2.38±0.74)分vs.(3.51±1.16)分,t=5.570,P<0.001]均优于对照组。2组治疗后前静息平均肌电值、后静息平均肌电值、快速收缩放松时间均较治疗前下降(均P<0.05),快肌最大肌电值、慢肌平均肌电值较治疗前升高(均P<0.05),研究组治疗后上述盆腔肌电生理指标均优于对照组(均P<0.05)。2组均未出现明显不良反应。 结论 骶神经磁刺激联合盆底肌康复训练能明显减轻女性CPP患者的疼痛,改善盆底肌力和肌电生理指标,是一种疗效显著且安全性好的康复治疗方案。 Abstract:Objective The use of sacral nerve intervention targets in chronic pelvic pain (CPP) has received much attention. This study aims to investigate the effectiveness of sacral nerve magnetic stimulation combined with pelvic floor muscle rehabilitation training in the treatment of female CPP. Methods A total of 92 female patients with chronic pelvic pain admitted to the pelvic floor clinic of Jinhua Maternal and Child Health Hospital from June 2022 to April 2023 were selected and randomly divided into a control group and a study group using a random number table method, with 46 cases each. The control group received myofascial manipulation combined with biofeedback pelvic floor muscle rehabilitation training, and the study group received sacral nerve magnetic stimulation combined with pelvic floor muscle rehabilitation training. Modified Oxford muscle strength grading (MOS), pelvic floor muscle tenderness examination, pelvic floor surface electromyography Glazer assessment and adverse reactions were compared between the two groups before and after treatment. Results After treatment, the MOS grading of the pelvic floor muscles was significantly improved in both groups compared with before treatment (all P<0.05), and the visual analogue pain score (VAS) of the pelvic floor myofascial trigger point (MTrP) was significantly reduced compared with before treatment (all P<0.05). In addition, the MOS grading of the pelvic floor muscles and the VAS score [(2.38±0.74) points vs. (3.51±1.16) points, t=5.570, P<0.001]in the study group were better than those in the control group. After treatment, the average pre resting electromyographic value, post resting average electromyographic value and rapid contraction relaxation time in both groups decreased compared to before treatment, while the maximum electromyographic values of the fast muscles and the average electromyographic values of the slow muscles increased compared to before treatment (all P<0.05). After treatment, the above pelvic electromyographic indicators were better in the study group than in the control group (all P<0.05). No significant side effects were observed in either groups. Conclusion Sacral nerve magnetic stimulation combined with pelvic floor rehabilitation training can significantly reduce pain, improve pelvic floor muscle strength and electrophysiological indicators in female patients with CPP and is a significant and safe rehabilitation treatment plan. -
