报告国人上、下肢共２４块肌于大脑皮层与脊髓电刺激时的运动诱发电位（ＭＥＰ）正常值。无论上肢或下肢，ＭＥＰ潜伏期均因肌肉所在位置而异，越是远端肌潜伏期越长，认为此乃脊神经长度不同所致。但中枢运动传导时间（ＣＭＣＴ）则与脊神经长度、肢长及身高无关，此为锥体束功能的最重要指标。肌肉轻度收缩时，皮层刺激的ＭＥＰ潜伏期缩短，波幅增高，认为系上运动神经元的易化所致。作者认为，ＭＥＰ的多导记录能减少刺激次数，一次性刺激即能同时获得多块肌的ＥＭＰ记录；有利于髓内和神经根病变的定位诊断。
Report on the Chinese people, the lower limbs a total of 24 muscles in the cerebral cortex and spinal cord stimulation when the motor evoked potential (MEP) normal. Regardless of the upper extremity or the lower extremity, the latency of MEP varies with the position of the muscle. The longer the latency of the distal muscle is, the longer the length of the spinal nerve is. However, CMCT is not related to the length, limb length and height of the spinal cord, which is the most important indicator of pyramidal tract function. Mild muscle contraction, the cortical stimulation of MEP latency shortening, increased amplitude, that Department of motor neurons caused by the facilitation. The author believes that MEP multi-guided recording can reduce the number of stimuli, one-time stimulation that can get more muscle EMP records; is conducive to intramedullary and nerve root localization diagnosis.
