运动神经元病为上、下运动神经元病变为主的系统性疾病,用X影象学检查及BAEP、SEP、VEP均不能全面揭示自运动皮质至周围效应器的运动通路变化。磁刺激运动诱发电位(MEP)能无损伤地直接检测中枢及外周运动通路的功能,从电生理角度对
Motor neuron disease is a systemic disease characterized by upper and lower motor neuron diseases. X-ray examination, BAEP, SEP and VEP can not fully reveal the change of motor pathways from motor cortex to peripheral effector. Magnetic stimulation of motor evoked potential (MEP) can directly detect the central and peripheral motor pathways without damage, from the electrophysiological point of view
