表面肌电及其生物反馈在下腰痛中的应用进展

Application progress of surface electromyography and surface electromygraphic biofeedback in low back pain

目的总结表面肌电(surface electromygraphy,sEMG)及表面肌电生物反馈(surface electromygraphic biofeedback,sEMGBF)在下腰痛的诊断和治疗中的应用进展。方法广泛查阅sEMG及sEMGBF在下腰痛中应用的相关文献,对其在下腰痛诊断和治疗方面的应用进行总结分析。结果 sEMG作为一种辅助诊断手段,发现下腰痛患者存在腰椎旁肌疲劳、躯干肌活动失调、屈曲放松现象缺失和椎旁肌肌电活动不对称等现象;在治疗方面,sEMG结合sEMGBF技术形成sEMGBF训练(包括sEMGBF训练和sEMGBF伸展训练),sEMGBF训练可改善腰背肌肌电异常活动,从而重塑腰背肌功能和缓解腰痛。结论 sEMG是一种监测肌电信号的手段,同时sEMGBF具有通过反馈信息控制肌肉训练使肌肉放松或力量增强的作用,对于下腰痛的辅助诊断和治疗有重要意义。

Objective To summarize the application progress of surface electromyography （sEMG） and surface electromygraphic biofeedback （sEMGBF） in low back pain （LBP）. Methods The related literature about the application of sEMG and sEMGBF in diagnosis and therapy of LBP was summarized and analyzed. Results As a auxiliary diagnostic technique, lumbar muscle fatigue, lumbar muscle activity disorder, flexion-relaxation phenomenon, and asymmetry of the paravertebral muscle electromygraphic activity were found in patients with LBP by sEMG. For treatment, sEMG combined with sEMGBF technology to form sEMGBF training. sEMGBF training include sEMGBF training and sEMGBF stretching exercise. sEMGBF training can improve lumbar muscle activity disorder, recover muscle function, and relieve back pain. Conclusion sEMG can monitor the electromyographic signal and sEMGBF biofeedback information can relax or strengthen the muscle. It is very meaningful for diagnosis and therapy of LBP.
