We examined whether driving-related reaction times differ between 26 healthy adults (university students) and 26 patients after stroke, and how distractors and leg-dominance affect reaction time and correctness of reactions of healthy adults. Reaction times were measured with the Fiat Mediatester driving simulator using 18-lamps reaction test (simple reaction time measurement) and choice reaction test (scored as reaction time and number of correct reactions). There was no statistically significant difference between the groups in simple reaction time. As expected, choice reaction times of the healthy adults were shorter on average and their reactions more accurate than those of the patients. Under the influence of distractors, healthy adults had statistically significantly longer choice and simple reaction times and made fewer correct choices compared to normal conditions. Leg dominance statistically significantly affected choice reaction times and correctness of reactions, but not simple reaction times. Our results confirm validity and usefulness of the Fiat Mediatester driving simulator for research purposes.
