목적 : 본 연구의 목적은 국립재활원에서 운전인지평가(CPAD: Cognitive Percpetual Assessment for Driving)를 받은 뇌졸중 환자들의 현재 운전실태를 조사하고 CPAD와 안전운전과의 연관성을 알아보기 위함이다. 방법 : 국립재활원에서 CPAD평가를 받은 뒤 전화인터뷰에 응한 48명의 뇌졸중 환자를 대상으로 하였다. 의무기록자료를 통해 기본적인 정보와 CPAD점수, KMMSE점수 등을 취득하였으며 전화설문을 통해 운전실태에 대하여 조사하였다. 결과 : 48명의 응답자 중 12명이 현재 운전을 하고 있다고 응답하였고, 36명은 운전을 하지 않고 있었다. 운전을 하고 있는 사람의 CPAD 평균 점수는 하지 않는 사람의 CPAD 평균 점수에 비해 더 높았다(평균=54.13 vs 47.80, p<0.05). CPAD의 합격군이 불합격군보다 현재 운전을 하고 있을 확률이 더 높았다(OR=8.3, 95%CI=1.9331-35.558). 결론 : CPAD의 합격군에 속하는 사람이 불합격군에 속한 사람보다 현재 운전을 하고 있을 확률이 더 높았으며, 사고를 경험할 확률이 더 낮았다. 따라서 CPAD는 운전과 관련이 있는 시지각 및 기타 인지기능 평가도구로 사용될 수 있을 것이다.

Brain injured patients who had the driver's license before the injury of the brain were tested with the newly developed tool CPAD by Hangyang Medical School and the National Rehabilitation Center. The CPAD contains many variables to measure the ability of driving. Also for each patient the American standard CBDI score was measured and the result was compared with the CPAD results. Of interest is to classify the patients as pass, border, fail group after the CPAD test. To derive the discriminant functions with the group information based on CBDI, parametric/nonparametric and multivariate/univariate discriminant analysis was performed and discussed.

Objective: The aim of this study was to perform a usability test for CPAD (Cognitive Perceptual Assessment for Driving) and improve it based on the test results. Background: The cognitive perceptual assessment for driving is a computer-based assessment tool to assess the driving capacity of people with brain-damages. It may be a good tool for evaluating the brain-damaged drivers' safe driving capabilities and screening cognitive and perceptual deficits related to driving. We performed a usability test to improve the CPAD based on the result. Method: Both the software consisting of 8 sub-tests (depth perception, sustained attention, divided attention, stroop test, field dependency, digit span, trail making A, trail making B) and the hardware including the input and output devices ( joystick, mouse, keyboard, touch screen) were evaluated through user interviews. Also we identified the problems and issues in using them by observing the participants performing the CPAD tasks. Results: Based on the results, the task instructions were visually and auditorily improved and more practice examples were added to help the users understand the instructions better and increase the input accuracy, a response time window was added and the joystick and touch screen were simplified, which made it easier for the user to perform the CAPD tasks. Conclusion: User discomforts were minimized by improving the task environment, unless it had affected the evaluation criteria. Application: We plan to distribute the improved version of the CPAD to the regional rehabilitation hospitals, and the driving support centers for people with disabilities throughout the country, so it could be used as an evaluation tool for disabled drivers' cognitive and perceptual functions.
