Abstrakt: Background: As the number of older drivers increases, concern has been raised about the potential safety implications. Flexibility, coordination, and speed of movement have been associated with older drivers' on road performance.Objective: To determine whether a multicomponent physical conditioning program targeted to axial and extremity flexibility, coordination, and speed of movement could improve driving performance among older drivers.Design: Randomized controlled trial with blinded assignment and end point assessment. Participants randomized to intervention underwent graduated exercises; controls received home, environment safety modules.Participants: Drivers, 178, age > or = 70 years with physical, but without substantial visual (acuity 20/40 or better) or cognitive (Mini Mental State Examination score > or =24) impairments were recruited from clinics and community sources.Measurements: On-road driving performance assessed by experienced evaluators in dual-brake equipped vehicle in urban, residential, and highway traffic. Performance rated three ways: (1) 36-item scale evaluating driving maneuvers and traffic situations; (2) evaluator's overall rating; and (3) critical errors committed. Driving performance reassessed at 3 months by evaluator blinded to treatment group.Results: Least squares mean change in road test scores at 3 months compared to baseline was 2.43 points higher in intervention than control participants (P = .03). Intervention drivers committed 37% fewer critical errors (P = .08); there were no significant differences in evaluator's overall ratings (P = .29). No injuries were reported, and complaints of pain were rare.Conclusions: This safe, well-tolerated intervention maintained driving performance, while controls declined during the study period. Having interventions that can maintain or enhance driving performance may allow clinician-patient discussions about driving to adopt a more positive tone, rather than focusing on driving limitation or cessation.
