Abstract

Somatosensory evoked potentials(SEPs) has been an important part of electrodiagnosis and has been utilized as a clinical diagnostic technique in various neurological disease. The purpose of this study was to evaluate the utility of SEPs in the analysis of sensory deficit as an objective method. The test was performed on the two groups of patients with cerebrovascular disease associated with motor and sensory impairment (grouip A) and pure motor impairment (group B), and then the results are compared with that of normal age-matched group. The results are as follows: 1. There is no significant difference in the abnormalities of N9 and N14 component between group A and B (P>0.05). 2. There is no significant difference in the decreased amplitude of N20 component (P>0.05), but there is a significant difference in the delayed peak latency or absent wave of N20 component(P<0.01) between group A and B. 3. There is a significant difference in the increased central conduction time between group A and B (P<0.01). 4. Although the difference is not significant statistically, there are more abnormalities of N20 or central conduction time in the intact hemispheres in group A than group B after stimulation of the median nerves of the affected sides.
