Purpose: The purpose of this study was to examine the effects of a cognitive training program on neurocognitive task performance and activitiesof daily living (ADL) in patients who had a stroke. Methods: The research design for this study was a nonequivalent control group non-synchronizeddesign. Patients were assigned to the experimental (n=21) or control group (n=21). The experimental group received a 4-week cognitivetraining program and usual care (i.e., rehabilitation service), while the control was received usual care only. Cognitive function was measuredwith a standardized neurocognitive test battery and ADL were assessed at baseline and one and two months after completion of the intervention. Repeated measures ANOVA was used to determine changes in cognitive function and ADL over 2 months. Results: The interaction of groupand time was significant indicating that the experimental group showed improvement in attention, visuospatial function, verbal memory, and executivefunction compared to the control group which had a sustained or gradual decrease in test performance. A significant group by time interactionin instrumental ADL was also found between the experimental with gradual improvement and the control showing no noticeablechange. Conclusion: Findings show that the cognitive training program developed in this study is beneficial in restoring cognitive function andimproving ADL in patients following a stroke. Further study is needed to investigate the long-term relationship between cognitive training participationand cognitive improvement and effective functioning in daily living.
