The effects of a Korean computer-based cognitive rehabilitation program on cognitive function and visual perception ability of patients with acute stroke.

[Purpose] The purpose of this study is to investigate the effects of a Korean computer-based cognitive rehabilitation program (CBCR) on the cognitive function and visual perception ability of patients with acute stroke. [Subjects] The subjects were 30 patients with acute stroke. [Methods] The subjects were randomly assigned to either the experimental group (EG) or the control group (CG). The EG subjects received CBCR with the CoTras program. The CG subjects received conventional cognitive rehabilitation. All subjects participated in a standard rehabilitation program according to a daily inpatient treatment schedule. In addition to standard rehabilitation, the subjects received 20 sessions (5 days a week for 4 weeks) of CBCR or conventional cognitive rehabilitation for 30 min. To compare the two groups, the Lowenstein Occupational Therapy Cognitive Assessment (LOTCA) and Motor-free Visual Perception Test-3 (MVPT-3) were performed. [Results] Both groups showed significant improvement in LOTCA and MVPT-3. Furthermore, there were significant differences in LOTCA and MVPT-3 between the two groups. [Conclusion] CBCR with CoTras may contribute toward the recovery of cognitive function and visual perception in patients with acute stroke.
