Effects of a Portable Computerized Cognitive Training System on the Visual-perceptual Function of Stroke Patients with Mild Cognitive Impairment : A Pilot Study

다국어 초록 (Multilingual Abstract)

This pilot study investigated the effects of a portable computerized cognitive training system on the visual-perceptual function of stroke patients with mild cognitive impairment. Subjects were twelve stroke patients with mild cognitive impairment, who were assigned to an experimental group (n=6) or a control group (n=6). All subjects were trained in their respective groups for 30 min/day, five times a week, for four weeks. In each session, the experimental group received a portable computerized cognitive training program, and the control group received conventional cognitive training. The Motor-Free Visual Perception-3 (MVPT-3) was used to measure subjects’ visual-perceptual ability. The MVPT-3 total scores for both groups significantly improved after the intervention (p<.05). The total score on the MVPT-3 and the score on the visual short-term memory subcategory of the MVPT-3 significantly improved for the experimental group compared to the control group (p<.05). These findings suggest that the portable computerized cognitive training system might be effective to improve the visual-perceptual function of stroke patients with mild cognitive impairment.
