Abstract:
Objective To explore effect of treatment of a non-surgical spinal decompression system(SDS) on neck muscle surface electromyography(EMG)of patients with cervical spondylotic radiculopathy(CSR).Methods Sixty patients with CSR in Department of Rehabilitation Medicine at The First Affiliated Hospital of Sun Yat-sen University in China between February 2014 and February 2016 were recruited and randomly divided into SDS group and control group,with 30 patients for each group.The SDS group and control group were treated with the SDS and general traction system for cervical traction respectively.Surface EMG telemeter was used to measure the surface EMG signals of the affected side cervical erector spinae muscle and sternocleidomastoid with the score of averaged EMG value(AEMG)and the median frequency(MF)as surface electromyogram signal evaluation indexes,and VAS and NDI as therapeutic effect evaluation indexes after a course of treatment.The data before and after the treatment were statistiacaly analyzed.Results During the first traction with tradtional traction or SDS,AEMG values of the cervical paraspinal muscle and sternocleidomastoi were significantly decreased and MF values significantly increased as compared with those before the traction (all P＜0.05).After a course of treatment,AEMG values of affected side cervical erector spinae muscle and sternocleidomastoi of SDS group were significantly decreased as compared with those before the treatment,and they were significantly lower in SDS group than in ordinary group (all P＜0.05);and MF values of affected side cervical erector spinae muscle and sternocleidomastoi in SDS group were significantly increased as compared with those before the treatment,and they were significantly higher in the SDS group than in the ordinary group (all P＜0.05).VAS and NDI scores of the two groups after a course of treatment were significantly lower than those before the treatment (P＜0.05),and VAS and NDI scores were significantly lower in the SDS group than in the ordinary group (P＜0.05).Conclusion SDS traction is superior to ordinary traction in relieving pain,improving function,relaxing neck muscles and alleviating muscle fatigue.
