Abstract:
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.
