表面肌电信号在腰椎间盘突出症的应用价值

Surface Myoelectric Signal Changes Evaluate the Effect of Needle Knife on Lumbar Intervertebral Disc Herniation

目的分析表面肌电信号变化评价针刀治疗腰椎间盘突出症的效果。方法回顾性分析本院2017年1月-2018年12月行针刀治疗的腰椎间盘突出症患者60例,通过表面肌电图比较治疗前后患者平均功率评率、中位评率的斜率、平均肌电波图,同时观察患者腰椎功能、直腿抬高角度、视觉疼痛评分。结果治疗后患者表面肌电图比较两组患者平均功率评率、中位评率的斜率、平均肌电波图,同时观察患者腰椎功能、直腿抬高角度、视觉疼痛评分优于治疗前患者临床比对有意义(P<0.05)。结论针刀治疗腰椎间盘突出症可恢复腰背伸肌,改善患者临床病症,通过表面肌电信号变化可有效评估患者治疗后平均功率评率、中位评率的斜率、平均肌电波图水平变化情况,便于临床准确、定量、客观的评价患者临床效果。

Objective To analyze the surface electromyographic signal changes and evaluate the effect of needle knife in treating lumbar intervertebral disc herniation.Methods Retrospective analysis was conducted to select 60 patients with lumbar intervertebral disc herniation treated with a needle knife from January 2017 to December 2018.The slope and average muscle wave charts of the two groups were compared by surface electromyography.The lumbar function,straight leg elevation angle and visual pain score were also observed.Results The surface electromyogram of the patients after treatment compared the slope and the mean myoelectric wave of the two groups.At the same time,it is significant to observe lumbar function,straight leg elevation angle,visual pain score and clinical comparison before treatment(P<0.05).Conclusion The treatment of lumbar intervertebral disc herniation with needle knife can restore the lumbar extensor muscle and improve the patient’s clinical condition.Through the change of surface electromyogram signal,the average power evaluation rate,the median position assessment rate,and the average muscle wave map level of the patient after treatment can be effectively assessed.It is convenient to evaluate the clinical effect of patients accurately,quantitatively and objectively.
