肌筋膜触发点电刺激对下肢截肢后幻肢痛的效果

目的 观察镜像疗法基础上肌筋膜触发点电刺激对下肢截肢后幻肢痛的临床疗效。方法 2020年5月至11月,本院下肢截肢后幻肢痛患者50例随机分为对照组(n = 25)和试验组(n = 25)。对照组采用镜像疗法,试验组于镜像疗法治疗前行肌筋膜触发点电刺激,共4周。治疗前后采用简化McGill疼痛问卷(SF-MPQ)、匹兹堡睡眠质量指数(PSQI)、汉密尔顿焦虑量表(HAMA)、计时“起立-行走”测试(TUGT)和6分钟步行测试(6MWT)进行评估。结果 治疗后,两组各项评定成绩均有显著改善(|t| > 8.210, P < 0.001);除SF-MPQ中现有疼痛强度外,试验组各项评分显著优于对照组(|t| > 5.103, P < 0.001)。结论 单纯镜像疗法可以减轻下肢截肢后幻肢痛患者的疼痛,提高睡眠质量,减轻焦虑,提高行走能力;加用肌筋膜触发点电刺激可进一步提高疗效。

Effect of Myofascial Trigger Points Electric Stimulation on Phantom Limb Pain after Lower Limb Amputation

Objective To explore the clinical efficacy of myofascial trigger point electric stimulation based on mirror therapy on phantom limb pain after lower limb amputation.Methods From May to November, 2020, 50 patients with phantom limb pain after lower limb amputation were randomly divided into control group (n = 25) and experiment group (n = 25). Both groups accepted mirror therapy, while the experiment group received myofascial trigger point electric stimulation before mirror therapy, for four weeks. They were assessed with short-form of McGill Pain Questionnaire (SF-MPQ), Pittsburgh Sleep Quality Index (PSQI), Hamilton Anxiety Scale (HAMA), Timed 'Up & Go' Test (TUGT) and 6-minute walk test (6MWT) before and after treatment.Results All the indexes improved in both groups after treatment (|t| > 8.210, P < 0.001), and improved more in the experiment group than in the control group (|t| > 5.103, P < 0.001), except the present pain intensity of SF-MPQ.Conclusion Mirror therapy is effective on phantom limb pain after lower limb amputation in terms of pain, sleep, anxiety and walking, and the effect could be stronger after myofascial trigger point electric stimulation.
