中枢运动传导时间

应用磁运动诱发电位（MEP）检测46例Graves（GD）病患者和50名正常对照组MEP潜伏期、波幅及中枢运动传导时间（CMCT）。

Magnetic motor evoked potentials ( MEP ) were measured in 46 patients with Graves ′ disease ( GD ) and 50 normal controls , and its latency 、 amplitude and central motor conduction time ( CMCT ) were recorded .

结果：急性期MEP的异常率为93%，主要表现为皮层MEP消失，中枢运动传导时间（CMCT）延长，波形异常及阈刺激强度增高。

Results : The abnormality rate of MEP during acute stage was 93 % with disappearance of cortical components , prolongation of central motor conduction time ( CMCT ), abnormality of waveforms and an increases in threshold stimulation intensity .
