Fourteen cervical spondylitic myelopathy (CSM) patients were clinically diagnosed and proved by MRI and surgery. The results of 11 patients showed that 8 (72.7%) had motor evoked potential (MEP) abnormality with prolongation of central motor conduction time (CMCT) in 7, and absence of motor action potentials after C7 stimulation in one. Five of the 11 patients showed normal somatosensory evoked potentials (SEPs) along the same arm. The short term (2-4 weeks) follow-up study in 10 patients showed normalization of the prolonged CMCT in one and reappearance of MEPs with C7 stimulation in another. Non-invasive and painless magnetic transcranial stimulation of the motor pathways is useful in the assessment and management of CSM patients, and is better than electrical stimulation.
14例脊髓型颈椎病（CSM）患者经临床诊断，并经MRI和手术证实。11例患者的结果显示，8例（72.7%）存在运动诱发电位（MEP）异常，其中7例中枢运动传导时间（CMCT）延长，1例在C7刺激后无运动动作电位。11例患者中有5例同一侧上肢的体感诱发电位（SEP）正常。对10例患者进行的短期（2 - 4周）随访研究显示，1例延长的CMCT恢复正常，另1例在C7刺激后MEP再次出现。对运动通路进行非侵入性、无痛的磁刺激对CSM患者的评估和治疗有用，且优于电刺激。
