摘　　要：目的 :探讨经颅磁刺激运动诱发电位 (MEP)在脑梗死中的应用价值。方法 :对 10 5例脑梗死患者进行检查。结果 :患者瘫痪侧上肢MEP潜伏期和中枢运动传导时间与健侧比较差异有高度显著性 (P <0 0 1)。MEP异常程度和临床症状呈正相关 ,且与治疗效果比较差异有显著性 (P <0 0 1) ,结论 :MEP反映中枢运动传导通路受损情况 ,对预测其预后亦有帮助。Objective: To explore the practicable value of Motor Evoked Potentials (MEP)in the cerebral infarcion Patients. Methods: 105 Patients with cerebral infarction were examined by motor evoked potentials of magnetic stimulation. Results: The two indices of MEP including incubation period and CMCT of paralytic side and well-being side of the upper extremities have great significant different(P<0.01). The abnormality of MEP and clinical symptom are positive correlation. The abnormality of MEP and therapeutic result have significant different(P<0.01). Conclusion: Early performed transcranial magnetic stimulation reflect the motor passage impairment and a valuable prognostic index of the clinical recovery.
