Abstract

OBJECTIVE
To evaluate the utility of Cognitive Perceptual Assessment for Driving (CPAD) through the on-road test in predicting the actual road driving skills in brain injured patients. METHOD: 25 brain injured patients with actual driving experience before the occurrence of diseases participated in the handicapped driving adaptation training program of our hospital as the subjects of the study, and one round of CPAD and on-road test were performed. CPAD evaluations and on-road tests for all patients were evaluated by the same therapist.
RESULTS
11 patients passed the CPAD and all of them passed the on-road test. 3 patients failed from CPAD and they turned out to be failed at the on-road test. The mean CPAD score of the on-road test passed group was 53.6 which was significantly different from the mean 43.6 CPAD score acquired by the on-road test failed group by showing a significant difference between two groups (p<0.05). Among the 11 patients who received the borderline CPAD score, 9 patients passed the on-road test.
CONCLUSION
CPAD is considered to be useful in predicting the actual road driving skills of brain injured patients who previously had driving experiences before the occurrence of the diseases.
