Development of the Korean stroke drivers’ screening assessment: A Pilot Study for adapting road sign recognition subtest

Abstract

Driving is an important activity of daily living affected by the motor and cognitive deficits after stroke. However, there are no standard practices of generally accepted and valid screening tools for stroke patients in Korea. Thus, This paper presents the development progress of an adapted version of the Stroke Drivers’ Screening Assessment (SDSA), which is a set of cognitive tests to evaluate fitness to drive in stroke patients. We adapted the original United Kingdom (UK) version of the SDSA to make it suitable for use in Korea by replacing all UK-specific traffic situations and road signs with their Korean equivalents. In order to apply the pass/fail SDSA equations of the original UK version of the SDSA, the road sign recognition subtest of K-SDSA was carefully investigated with healthy older drivers and revised the road scenarios to match with their UK peers’ scores. Final validity of the pass/fail SDSA equations were conducted by comparing the stroke patients’ driving performance in a driving simulator.
