肌电生物反馈治疗臂丛神经损伤的临床研究

Clinical research of electromyogram biofeedback therapy on brachial plexus injury

目的观察肌电生物反馈对臂丛神经损伤治疗前后的表面肌电活动变化,并与常规治疗效果相比较,探讨肌电生物反馈对臂丛神经损伤的疗效。方法将臂丛神经损伤患者24例,随机分为2组,其中对照组12例采用常规针灸、运动治疗,治疗组12例在常规治疗的基础上,加用肌电生物反馈治疗,采用表面肌电图收缩的最大波幅、肌电积分值来评定疗效并进行统计学分析。结果治疗后两组各项指标与治疗前比较均有改善,但两组间差异有统计学意义(P<0.05)。结论肌电生物反馈治疗结合常规针灸、运动治疗较单纯常规治疗能更有效地提高臂丛神经损伤的治疗效果。

AIM：To observe the changes of surface electromyogram （sEMG） of electromyogram biofeedback therapy on brachial plexus injury, compared with conventional treatment,so as to investigate the curative effect of electromyogram biofeedback therapy on brachial plexus injury. Methods：24 patients whose brachial plexus were injury were divided into 2 groups randomly：a control group and a therapy group. 12 patients of the control group were treated with routine acupuncture and physical therapy. 12 patients of the therapy group were treated with electromyogram biofeedback on the basis of routine therapy. All patients’ maximum amplitude and electromyographic integral value were recorded to estimate curative effect and analyze statistics. Results：All the indications of the two groups were improved,compared with pretherapy. There were distinctive differences between the two groups.Conclusion：Electromyogram biofeedback therapy in conjunction with routine acupuncture and physical therapy can increase curative effect on brachial plexus injury more effectively than conventional therapy.
