颈型颈椎病曲率与颈部肌肉疲劳度相关性分析

Study on the correlation between cervical spondylosis curvature and neck muscle fatigue

摘要

摘要:
目的探讨颈型颈椎病生理曲度的弓深值D与距离H的比值和疼痛侧斜方肌上束、胸锁乳突肌表面肌电图的中位频率(median frequency, MF)的相关性。
方法健康对照组20名, 颈型颈椎病颈部单侧疼痛病人50例, 均进行颈椎正侧位X线片和采集疼痛侧胸锁乳突肌、斜方肌上束表面肌电值的MF。使用Pearson相关性检验分析D/H与疼痛侧胸锁乳突肌、斜方肌上束表面肌电值的MF参数之间的相关性。
结果与健康对照组比较, 生理曲度水平上, 健康对照组>生理曲度变直组>生理曲度反弓组(P < 0.01)；Pearson相关分析显示, D/H与疼痛侧胸锁乳突肌MF、疼痛侧斜方肌MF存在明显的正相关关系(r=0.847、0.811, P < 0.01)。
结论表面肌电图中颈部肌肉疲劳度的测定可以作为评估颈型颈椎病病人的一种无创便捷的方法；颈部肌肉表面肌电的评估可以为日后预防、诊断和治疗颈型颈椎病提供指导意义。

Abstract:
Objective To investigate the correlation between the ratio of arch depth(D) to distance(H) of physiological curvature of cervical spondylosis and median frequency(MF) of the surface electromyography(EMG) of upper band of trapezius muscle and sternocleidomastoid muscle on the pain side.
Methods The anteroposterior and lateral radiographs of the cervical spine and MF of surface EMG values of the upper bundle of sternocleidomastoid muscle and trapezius muscle on the pain side in 20 healthy people(control group) and 50 cervical spondylosis patients with unilateral neck pain were detected.The Pearson correlation test was used to analyze the correlation between D/H and MF parameters of the surface EMG values of upper band of trapezius muscle and sternocleidomastoid muscle on the pain side.
Results Compared with the healthy control group, the physiological curvature levels in the healthy control group, physiological curve straightening group and physiological curve angulation group gradually declined (P < 0.01).The results of Pearson correlation analysis showed that the D/H was positively correlated with MF of surface EMG values of sternocleidomastoid muscle and trapezius muscle on the pain side (r=0.847, 0.811, P < 0.01).
Conclusions The measurement of cervical muscle fatigue in surface EMG can be used as a noninvasive and convenient method to evaluate the patients with cervical spondylosis.The evaluation of surface EMG of neck muscle can provide a guidance in the prevention, diagnosis and treatment of cervical spondylosis in the future.
