The incidence of visual deficits following stroke ranges from 20%-68% and has
significant impact on activities of daily living. The NVT system is a
compensatory visual scanning training program that consists of combined static
and mobility training and transfer to activities of daily living.
The study aims
to evaluate functional changes following the NVT program for people who have
homonymous hemianopia (HH) following stroke. METHOD: Interventional case series
of 13 consecutive participants with HH undergoing NVT vision rehabilitation. The primary outcome measure was the number of targets missed on a standardized
Mobility Assessment Course (MAC). Other outcome measures included assessment of
visual scanning, vision specific Quality of Life questionnaires and reading
performance. RESULTS: The average number of targets (sd) missed on the MAC course
was 39.6 +/- 20.9% before intervention, 27.5 +/- 16.3% immediately post
intervention and 20.8 +/- 15.5% at 3 months post rehabilitation. The study showed
a statistically significant trend in improvement in mobility related subscales of
National Eye Institute Visual Function Questionnaire-NEI VFQ-25 (p=0.003) and the
Veteran Affairs Low Vision Visual Function Questionnaire-VA LVFQ-48 (p=0.036) at
3 months post rehabilitation. DISCUSSION: The NVT intervention resulted in
functional improvements in mobility post rehabilitation.
The NVT training showed
improvement in vision specific quality of life. There is a need for standardised
vision therapy intervention, in conjunction with existing rehabilitation
services, for patients with stroke and traumatic brain injury.
