OBJECTIVE: To evaluate the effectiveness of retraining
using the Dynavision on driving performance of people with stroke. DESIGN:
Randomized controlled trial. SETTING: Outpatient rehabilitation clinic in
Australia. PARTICIPANTS: People with stroke (N=26) referred for driving
assessment. INTERVENTIONS: Eligible participants were randomized to either
receive retraining with the Dynavision apparatus for 18 sessions or to receive no
intervention and go onto a waitlist. MAIN OUTCOME MEASURES: The primary outcome
was an assessment of on-road ability. Secondary outcomes included measures of
response speed, visual scanning, and self-efficacy. All assessments were
conducted by assessors blinded to group assignment. RESULTS: No significant
difference (P=.223) was found between the intervention and control groups in
results of on-road assessment in terms of pass or fail; the primary outcome
measure; or the results on the secondary outcome measures of response speed,
visual scanning, and self-efficacy. CONCLUSIONS: In this small trial, training
underlying skills (such as executing a continuous wide scan, combining motor and
visual processing into a motor response) using the Dynavision apparatus did not
improve the outcomes of an on-road assessment for people after strokes. Larger
trials are needed to evaluate devices that claim to retrain underlying skills
related to driving.
