肌电图联合MRI定位多节段腰椎间盘突出脊柱减压的疗效观察

The Effect of Spinal Decompression after Localization with Electromyography and MRI for Plurisegmental Lumbar Disc Herniation

目的观察应用肌电图和MRI联合定位多节段腰椎间盘突出的病变节段,行非手术脊柱减压系统治疗腰椎间盘突出症的疗效。方法共纳入40例多节段腰椎间盘突出症患者,采用随机数字表法分为联合定位组(应用肌电图和MRI联合定位)和对照组(应用MRI结合临床体征定位),每组20例,两组均给予非手术脊柱减压系统DRX9000治疗。分别于治疗前、治疗6周后对两组患者进行目测类比评分法(VAS)、下腰痛JOA评分量表的评定。结果两组患者经过治疗6周后,VAS评分、下腰痛JOA评分量表均较治疗前有明显改善(P<0.05),其中,VAS评分联合定位组优于对照组(P<0.05),JOA评分联合定位组较对照组高,但差异无统计学意义(P>0.05)。结论应用肌电图和MRI联合定位多节段腰椎间盘突出的病变节段,较单纯应用MRI结合临床体征定位准确,从而使非手术脊柱减压治疗更有效,值得临床广泛推广。

Objective To observe the effect of nonsurgical spinal decompression system after localization with electromyography andMRl for plurisegmental lumbar disc herniation. Methods 40 patients with plurisegmental lumbar disc herniation were divided intotwo groups 院 one was located with electromyography and MRI (the combined location group,n =20), the other was located with MRland clinic signs(the control group,n=20). Both groups were treated with nonsurgical spinal decompression system DRX9000 .Thepatients of both groups were assessed pre-,6 weeeks post-treatment with VAS pain score, low back pain JOA score. Results The VASpain scores and low back pain JOA scores of both groups were improved after 6 weeeks treatment (P < 0.05). Compared with thecontrol group,VAS of the combined location group was improved more significantly (P < 0.05) while JOA was not. Conclusion The localization with electromyography and MRI for plurisegmental lumbar disc herniation is more accurate than that with mereMRI and clinic signs,which can lead nonsurgical spinal decompression system work more effectively, deserving of generalization.
