摘要
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。
Objectives:To explore the relationship between the sensory disturbances and the abnormality of somatosensory evoked potentials in patients with cerebrovascular disease.Methods:A comparative study was performed on somatosensory evoked potentials (SEP) in 49 cases of cerebrovascular disease (CVD) including 28 patients with sensory disturbances and 21 patients only with motor disturbances but wthout sensory disturbances, and 10 normal subjects. Results:The central conduction time (CCT) of SEP was prolonged in the affected side in group of sensory disturbance. A significant difference was noted as compared with the nonaffected side and normal subjects. The abnormality rate of amplitude ratios in both N 20 _P 25 and P 15 was significantly higher than thConclusions:These data suggested that a close relationship exists between SEP changes and sensory disturbances in CVD. SEP might be an objective indicator in judging the existence of sensory disturbances in CVD.
