We compared the effect of computerized-assisted cognitive rehabilitation (CACR) and conventional rehabilitation (CR) on visuospatial perception, visual field and attention, and visual memory in patients with unilateral spatial neglect.
Twenty patients with unilateral spatial neglect from brain injury were randomized into the experimental group (n = 10) or the control group (n = 10). The experimental group received CACR intervention from RehabCom software, including saccadic eye movement, visual field, and visual-motor coordination training, whereas the control group received CR with 30 minutes for each intervention, five times a week for 4 weeks. Outcome measures were Motor-Free Visual Perception Test (MVPT) and Line Bisection Test (LBT) for visuospatial perception, Visual Span Test (VST) for visual field and attention, Visual Recognition Test (VRT) for visual memory, evaluated before and after each of intervention. A statistically significant difference was found in MVPT (p < 0.01), VST (p < 0.01), VRT (p < 0.01) between the groups after adjusting for baseline values but not in the LBT. Furthermore, the effect sizes showed a large effect on the MVPT and VRT and a moderate effect on the VST in favor of the CACR (Cohen’s d = 1.06, 1.12, 0.67, and 0.58, respectively). Both groups demonstrated statistically significant improvement in all variables (p < 0.01).
The CACR was found to be more beneficial than CR at improving visuospatial perception, visual field and attention, and visual memory, implying that the CACR may be an effective intervention to treat the unilateral spatial neglect caused by brain damage
