非手术脊柱减压系统牵引对慢性颈痛患者颈部肌肉表面肌电信号的影响

摘要

Objective To explore effect of non-surgical spinal decompression system (SDS) traction on neck muscle surface electromyography (EMG) of patients with chronic neck pain. Methods 100 patients with chronic neck pain in Rehabilitation Department of Motion Rehabilitation Research Center of Shandong Province and Rehabilitation Depart-ment of Qilu Hospital from February 2013 to February 2015 were selected and randomly divided into SDS group and ordinary group, with 50 cases in each group. The patients of SDS group and ordinary group were treated with SDS and general traction system for cervical traction respectively. Surface EMG telemeter was used to measure affected side cer-vical paraspinal muscle and cervical erector spinae muscle surface EMG, and VAS and NDI score after a course of treatment were observed. Results There were statistical differences between two groups of EMG amplitude and frequen-cy slope of affected side cervical paraspinal muscle before, during and after traction for the first time (P<0.05). After a course of treatment, affected side cervical paraspinal muscle EMG amplitude and frequency slope of SDS group were significantly higher than those of ordinary group (P<0.05). There were statistical difference between two groups of EMG amplitude and frequency slope of cervical erector spinae muscle before, during and after traction for the first time (P<0.05). After a course of treatment, cervical erector spinae muscle EMG amplitude and frequency slope of SDS group were significantly higher than those of ordinary group (P<0.05). VAS and NDI score of two groups after a course of treat-ment were significantly lower than those before treatment (P<0.05), and VAS and NDI score of SDS group were signif-icantly lower than those of ordinary group (P<0.05). Conclusion SDS traction is superior to ordinary traction as to the func-tion of relaxing neck muscles and relieving muscle fatigue, much superior as to the treatment effect of chronic neck pain.%目的：探讨非手术脊柱减压系统(SDS)牵引对慢性颈痛患者颈部肌肉表面肌电信号的影响。方法选择2013年2月~2015年2月山东省运动康复研究中心康复科和齐鲁医院康复科收治的慢性颈痛患者100例,随机分为SDS组和普通组,各50例,分别采用SDS和普通牵引系统进行颈椎牵引,采用表面肌电图。测仪测患侧颈棘旁肌、颈竖脊肌表面肌电图,并观察治疗1个疗程后视觉模拟评分(VAS)和颈椎功能障碍指数(NDI)评分。结果两组首次牵引前、中、后患侧颈棘旁肌肌电振幅及频率斜率差异均有统计学意义(P<0.05)。治疗1个疗程后,SDS组颈棘旁肌肌电振幅及频率斜率明显高于普通组(P<0.05)。两组首次牵引前、中、后患侧颈竖脊肌肌电振幅及频率斜率差异均有统计学意义(P<0.05)。治疗1个疗程后,SDS组患侧颈竖脊肌肌电振幅及频率斜率明显高于普通组(P<0.05)。治疗1个疗程后,两组VAS和NDI评分均较治疗前明显降低(P<0.05),SDS组VAS和NDI评分均明显低于普通组(P<0.05)。结论 SDS牵引较普通牵引对颈部肌肉放松、减轻肌肉疲劳的作用优于普通牵引,对治疗慢性颈痛的效果更优。
