摘　　要：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 diseases were examinied by motor evoked potentisls of magnetic stimulation (MEP), and 57 patients of them were examined by short lantency somatosensoryevoked potential (SSEP) at the same time. We also made a comparative study between the patients and 50 normal controls. The results showed that no reaction by magnetic stimulation, or the latencies of conical motor evoked potentisls and CMCT for these upper paralytic extremities in patients with cerebrovascular diseases had high significant delayed in comparison with normal controls and unaffected side (P<0. 001) ; and no reaction by magnetic stimulation, or CMCT for these paralytic lower extremities in patients with cerebrovascular diseases had significant prolonged (P<0. 05). The abnormal rate of MEP and SSEP had no significant different in patients with hemorrhages and infarcts (P>0. 05) ; but it was correlated with the clinical showing and lesion location. This article indicated that MEP and SSEP and objectively reflect the damage of the central motor pathes and central sensory pathes in patients with cerebrovascular diseases respectively.
