摘要
目的 探讨非手术脊柱减压系统（SDS）对腰椎间盘突出症（LDH）患者腰椎旁肌表面肌电信号的影响。 方法 选取12例磁共振检查诊断为L4-5椎间盘突出症的患者，依入院顺序按随机数字表法分为SDS组和对照组，每组6例，分别行单次SDS治疗和腰椎牵引治疗。分别于治疗前、治疗中和治疗后，采用表面肌电记录2组患者椎旁肌的平均肌电（AEMG）值并进行统计学分析比较。 结果 治疗前，SDS组患者右竖脊肌、左竖脊肌、右多裂肌和左多裂肌的AEMG值分别为（2.222±0.194）μV、（1.802±0.138）μV、（1.893±0.196）μV和（1.925±0.152）μV，对照组的AEMG值依次为（7.128±1.476）μV、（7.559±2.119）μV、（6.375±1.728）μV和（5.163±1.011）μV，组间差异有统计学意义（P〈0.05）。治疗过程中，SDS组右竖脊肌、右多裂肌的AEMG值分别为（2.343±0.286）μV和（1.792±0.165）μV，对照组依次为（8.779±1.680）μV和（11.921±5.490）μV，组间差异有统计学意义（P〈0.01）。治疗后，SDS组右竖脊肌和右多裂肌的AEMG值分别为（2.242±0.276）μV和（1.840±0.142）μV，对照组依次为（9.168±2.266）μV和（9.091±3.413）μV，组间差异有统计学意义（P〈0.01）。 结论 与单次腰椎牵引相比，单次SDS治疗能明显降低患者腰椎旁肌的紧张度，减轻肌肉疲劳。
Objective To explore the effect of non-surgical spinal decompression （SDS） on the surface electromyogram signals from the paraspinal muscles of patients with lumbar disc herniation （LDH）. Methods Twelve patients diagnosed with L4-5 LDH were recruited and randomly divided into an SDS group and a control group, each of 6 according to their order of admission. The SDS group received spinal decompression, while the control group was given lumbar traction. The average surface electromyogram signals （AEMGs） were recorded before, during and after the treatment. Results Before the treatment, the AEMG values collected from the left and right erector spinae and multifidus of the SDS group were already significantly different from those of the control group. During the treat- ment, the AEMG values collected from the right erector spinae and multifidus of the SDS group remained significantly different from those of the control group. After the treatment, the AEMG values were still significantly different. Conclusions SDS relieves tension and fatigue of the paraspinal muscles better than lumbar traction.
