Brainstem auditory evoked potential was done in 28 normal persons and 23 chronic head injury and CVA patients with rarefaction click sound stimulation at 50,70,90dB intensities. Degree of BAEP distortion, V wave absolute, V-I interpeak latencies were correlated with Disability Rating Scale scores. And followings are the results.
1) There was no significant difference between normal and patient groups in absolute and interpeak latencies. 2) In normal group, the absolute latencies of Ⅲ, V waves and V-I interpeak latencies were faster in female, in younger age and at higher stimulation intensity. 3) There was no significant differences between DRS scores and BAEP latencies. 4) BAEP wave distortions measured by Anderson Scale were more colsely related with stimulation intensities rather than DRS scores.
