摘　　要：目的:联合肌电图(EMG)与体感诱发电位(SEP)检查探索神经根型颈椎病手术治疗的客观指征。方法:72例待行颈椎前路减压植骨融合术治疗的神经根型颈椎病患者,根据肌电图与体感诱发电位检查结果分为轻、中、重度3组。比较3组患者颈椎功能障碍指数(NDI)的恢复程度。结果:根据EMG与SEP检查结果,轻度组患者21例,中度组患者26例,重度组患者25例。3组术后NDI评分均较术前有显著恢复(P<0.05),轻、中度组恢复至轻度功能障碍,重度组恢复至中度功能障碍。结论:肌电图或体感诱发电位异常,而腋神经运动潜速率正常且SEP的N13波形尚清晰是神经根型颈椎病接受手术治疗的电生理指征。Objective： To explore the objective indications for surgical treatment of cervicalspondylotic radiculopathy combining electromyogram （ EMG ） with somatosensory evoked potentials （ SEP ） . Methods： Seventy-two patients with cervicalspondylotic radiculopathy, who were ready to undergo anterior cervical decompression and fusion, were divided into three groups （ the mild group, the moderate group and the severe group ） according to the results of EMG and SEP tests. The recovery degree of the neck disability index （ NDI ） were compared. Results： According to the EMG and SEP findings, there were 21 cases in the mild group, 26 cases in the moderate group and 25 cases in the severe group. The postoperative NDI scores were significantly improved in all patients （P 〈 0.05 ） . The NDI scores of the mild group and the moderate group restored to mild dysfunction, and the severe group＇s scroe restored to moderate dysfunction. Conclusion： Abnormal EMG or SEP with normal axillary motor nerve conduction velocity and clear SEP N13 waveforms indicate the best electrophysiological status of cervicalspondylotic radiculopathy for surgery.
