目的 通过测定脑血管病患者发病后运动诱发电位 (MEP) ,验证MEP在预测梗死后运动功能恢复中的作用。方法 选取 2 9例大脑中动脉梗死的患者 ,在发病的第 1日行经颅磁刺激 (TMS)检查 ,记录其MEP ,同时进行临床评价 ,在发病的第 2 8日 ,所有检查再重复一次。结果 在发病第 1日能够引出MEP的患者 ,其预后较不能够引出的患者运动功能恢复好。结论 对脑梗死患者在急性期行MEP检查 ,是评价患者将来运动功能康复的一项客观、安全、有效的预测手段。
Objective To investigate the role of MEP in predicting motor function recovery after stroke by measuring the post-operative motor evoked potential (MEP) in patients with cerebrovascular disease. Methods Twenty-nine patients with middle cerebral artery infarction were enrolled in this study. TMS was performed on the first day of the disease. The MEP was recorded and clinical evaluation was performed. On the 28th day of the onset, all the tests were repeated. Results In patients who developed MEP on the first day of onset, their prognosis was better than that in patients who were not able to elicit them. Conclusions MEP examination in patients with acute cerebral infarction is an objective, safe and effective method to evaluate the rehabilitation of motor function in patients with cerebral infarction.
