摘　　要：目的:应用针刀治疗腰椎间盘突出症(LDH),采用表面肌电图分析患者腰部肌肉生物力学特性,并对其疗效进行全面评价。方法:选取符合纳入标准的患者30例,采用针刀治疗,1周1次,共2次。观察治疗前后视觉疼痛量表(VAS)评分、直腿抬高角度(ASLR)和腰椎功能JOA评分,应用表面肌电图采集患者治疗前后表面肌电信号,计算并比较治疗前后的平均肌电波幅(AEMG)、中位频率的斜率(MFs)和平均功率频率(MPF)。结果:治疗后VAS评分减低,ASLR、JOA评分、AEMG和MPF增加,MFs绝对值降低,差异均具有统计学意义(均P<0.01)。结论:针刀治疗能显著缓解LDH患者腰部肌肉的肌力、肌张力和肌肉疲劳程度,改善LDH患者腰背伸肌群失衡状态,从而有利于恢复LDH患者腰背伸肌的生物力学特性,临床疗效显著。Objective To apply needle-knife to treat lumber disc herniation （LDH） and surface electrornyogra- phy were used to analyze biomechanical characteristic of patient＇s lumber muscle to make a comprehensive evalua- tion on its efficacy. Methods Thirty patients who met the inclusive criteria were selected and treated with needle- knife, once a week for 2 weeks. Visual analogue scale （VAS）, ASLR and JOA score before and after treatment were observed. Surface electromyography was applied to test the surface electromyography signals. AEMG, MFs and MPF were calculated before and after the treatment. Results After treatment, VAS was significantly re- duced, ASLR, JOA, AEMG and MPF were obviously increased, and the absolute value of MFs was lowed （all P〈0.01）. Conclusion The needle-knife could significantly relieve lumbar muscle strength, muscle tone and muscle fatigue, improve in the imbalance of lumbar extensor muscle group, leading to the recovery of biomechanical char- acteristic, and the clinical efficacy is superior.
