Functional impairments and health conditions with driving performance
This paper examined the relationship between functional impairments (vision problems, movement issues), co-morbid conditions, and driving performance in a sample of cognitively normal older adults. We looked at visual acuity, contrast sensitivity (how well you see very faint letters), physical frailty measures, motor skills, total medical conditions, and the on-the-road driving evaluation. We found that the total number of medical conditions that a participant had was not associated with the outcomes of the driving test. However, there were marginal associations between physical frailty, contrast sensitivity, and total driving errors on the driving evaluation.
