Abstract

Driving simulators are increasingly used to assess the driving capabilities of persons with neurodegenerative conditions. However, few driving simulator evaluations have been validated against standardized on-road tests. The aim of this study was to investigate the concurrent validity of a comprehensive driving simulator evaluation in 29 persons with Huntington disease (HD). The Test Ride for Investigating Practical fitness to drive (TRIP) checklist was administered after a 15 km simulator drive and 20 km on-road drive. The total driving simulator TRIP score and each of its item scores were compared with the on-road TRIP scores using Spearman rho correlation statistics. We found significant correlations for 9 of the 12 items. Correlations ranged between 0.12 for the item gap distance at speed below 50 km/h and 0.72 for the total TRIP score, indicating variable strength of the associations. Items assessing operational skills correlated better with on-road driving performance than tactical or higher-order visual items. The results indicate that a fixed-base, single screen driving simulator is a valid tool to assess on-road driving capabilities in persons with HD.
