Visual inattention is a major cause of road accidents and is a
problem commonly experienced after stroke. Purpose: This study investigated the
effects of 2 training programs on performance in the Useful Field of View (UFOV),
a validated test of driving-related visual attention skills. METHOD: Data from 69
first-ever, moderately impaired stroke survivors who participated in a randomized
controlled trial (RCT) to determine the effects of simulator training on driving
after stroke were analyzed. In addition to regular interventions at a
rehabilitation center, participants received 15 hours of either simulator-based
driving-related training or non-computer-based cognitive training over 5 weeks.
RESULTS: Total percentage reduction in UFOV and performance in divided and
selective attention and speed of processing subtests were documented at 6 to 9
weeks (pretraining), 11 to 15 weeks (posttraining), and 6 months post stroke
(follow-up). Generalized estimating equation (GEE) model revealed neither group
effects nor significant interaction effects of group with time in the UFOV total
score and the 3 subtests. However, there were significant within-group
improvements from pre- through posttraining to follow-up for all the UFOV
parameters. Post-hoc GEE analysis revealed that most improvement in both groups
occurred from pre- to posttraining. CONCLUSION: Both training programs
significantly improved visual attention skills of moderately impaired stroke
survivors after 15 hours of training and retention of benefit lasted up to 6
months after stroke. Neither of the training programs was better than the other.
