This study aimed to compare the effects 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. Forty-eight patients with unilateral spatial neglect were randomly assigned to either the experimental group (n=23) or the control group (n=25). The experimental group received CACR intervention using RehaCom software, including saccadic eye movement, visual field, and visual-motor coordination training, whereas the control group received CR, including hemispheric activation approach, mental imagery training, and vibration therapy. Interventions for the experiemntal and control groups were performed for average 30 minutes, five times per week for four weeks. Outcome measures comprised Motor-free visual perception test (MVPT) and line bisection test (LBT) for visuospatial perception, visual span test (VST) for evaluating visual field and attention, and Visual recognition test (VRT) for evaluating visual memory. Evaluations were performed before and after the intervention. In between-group comparison, improvements on MVPT, VST, and VRT scroes after the intervention were statistically significantly different between the groups (p<.01). In within-group comparison, both groups showed statistically significant improvement in all variables after the intervention (p<.01). These findings suggest that the CACR may be beneficially used to enhance visuospatial perception, visual field and attention, and visual memory for patients with the unilateral spatial neglect caused by brain damage. Further studies will be needed to warrant our results.
