目的：探讨脑血管病（ＣＶＤ）病人感觉障碍与体感诱发电位（ＳＥＰ）异常间的关系。方法：对ＣＶＤ２８例感觉障碍的病人，２１例只有运动障碍而无感觉障碍的病人和１０例正常人进行了ＳＥＰ研究。结果：感觉障碍组患侧中枢传导时间（ＣＣＴ）延长，与非患侧和正常对照组比较，差异均有显著性意义（Ｐ＜０．０５）。感觉障碍组Ｎ２０－Ｐ２５和Ｐ１５波幅比的异常率均明显高于无感觉障碍组。结论：ＣＶＤ的感觉障碍与ＳＥＰ的异常密切相关，ＳＥＰ可以做为判断ＣＶＤ时存在感觉障碍的客观指标
Objective: To investigate the relationship between sensory disturbance and somatosensory evoked potential (SEP) abnormalities in patients with cerebrovascular disease (CVD). METHODS: SEP was performed in 28 patients with CVD, 28 patients with dyskinesia, and 10 normal controls. Results: The central conduction time (CCT) in sensory disturbance group was longer than that in non - affected and normal controls (P <0.05). Sensory dysfunction group N20-P25 and P15 amplitude ratio abnormalities were significantly higher than those without sensory disturbances. Conclusion: The sensory disturbance of CVD is closely related to the abnormality of SEP, and SEP can be used as an objective index to judge the presence of sensory disturbance during CVD
