采用经颅磁刺激运动诱发电位（MEP）对72名脑血管病患者进行检测，其中57例还同时测定短潜伏期体感诱发电位（SSEP），并和50例正常人进行对比研究．结果发现脑血管病患者瘫痪侧上肢MEP异常表现为刺激无反应或皮层潜伏期延长和中枢传导时间延长，与正常对照组和健侧比较差异有极高度显著性（P＜0．001），瘫痪侧下肢MEP异常表现为刺激无反应或中枢传导时间延长，与正常对照组和健侧比较，差异有显著性（P＜0．05）．MEP和SSEP异常率在脑出血与脑梗塞之间无显著性差异（P＞0．05），而与临床表现和病变部位密切相关。本文提示MEP和SSEP分别能客观地反映脑血管病愈者中枢运动传导通路和中枢感觉通路功能受损的情况．
72 patients with cerebrovascular disease were tested by transcranial magnetic stimulation motor evoked potentials (MEP), of which 57 patients were also tested for short latency somatosensory evoked potential (SSEP) and compared with 50 normal subjects. The results showed that abnormal MEP in paralyzed side cerebral infarction patients with cerebrovascular disease manifested as stimulating no reaction or prolonging cortical latency and prolonging central conduction time, which were highly significant compared with normal control group and contralateral group (P <0.001) The abnormalities of MEP in the lower extremities showed no stimulation or prolonged central conduction, which was significantly different from the normal control group and contralateral group (P <0.05). The abnormal rates of MEP and SSEP had no significant difference between cerebral hemorrhage and cerebral infarction (P> 0.05), but were closely related to the clinical manifestations and the location of lesions. This paper suggests that MEP and SSEP can objectively reflect the central vascular access and central sensory pathway dysfunction in patients with cerebrovascular disease.
