Summary
This study evaluated the effectiveness of four standardized rehabilitation training programs designed to improve driving performance among healthy older adults. The research was motivated by the growing population of older drivers and the proliferation of commercial training programs claiming to mitigate age-related declines in vision, cognition, and physical function. The primary objective was to determine whether these interventions could demonstrably improve tactical driving skills, as measured by on-road assessments and driving simulator tasks, compared to a control group. The researchers conducted a randomized controlled trial involving 100 volunteers aged 65 and older, recruited from a rehabilitation hospital in South Carolina. Participants were randomly assigned to one of four treatment groups or a control group. The interventions included: (1) classroom driver education supplemented by behind-the-wheel instruction; (2) computer-based exercises targeting speed of processing and divided attention; (3) occupational therapy (OT)-administered exercises focusing on visual skills and attention; and (4) physical conditioning to improve strength and flexibility. The control group received relaxation training or health counseling unrelated to driving. Each group received eight hours of direct contact. Performance was assessed by a certified driver rehabilitation specialist (CDRS) blind to group assignment using on-road evaluations of 33 tactical and strategic skills, as well as simulator tests measuring response times under divided attention conditions. Assessments occurred at baseline, immediately post-training, and three months post-training. The results indicated limited efficacy across the interventions. On-road assessments revealed that only the OT-administered visual skills training group demonstrated a significant gain relative to the control group in maintaining skills among drivers who had no baseline deficits. Additionally, both the OT-administered group and the classroom plus behind-the-wheel group showed significant improvements among drivers who had baseline deficits, but these gains were observed only in the immediate post-training assessment. No treatment group demonstrated significant gains at the three-month follow-up. Simulator results were equivocal, with no significant gains in response times for any group relative to controls, although the OT and classroom groups performed best on peripheral hazard detection latency. The study concludes that OT-administered visual skills training offers a viable method for enhancing safety among older drivers, particularly because it can be administered by professionals without specialized driver rehabilitation certification. The findings suggest that while some interventions yield immediate tactical improvements, effects are not sustained over three months. The authors recommend further research to develop standardized on-road evaluation methods with interval properties and to explore the broader implementation of OT-based curricula in clinical settings. Limitations included small sample sizes and the use of an ordinal scoring system that restricted statistical analysis.
Key finding
Only the occupational therapy-based visual skills training demonstrated significant gains in maintaining driving skills for deficit-free drivers and improving skills for drivers with initial deficits on on-road assessments, while no training group showed significant improvements in simulator performance.
