NeuroRehabilitation, 05/17/2012Hayes A et al.
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.
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.
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.
