Abstract

|
|
Objective : The purpose of this study was to verify the clinical effect of a Korean computer-based cognitive rehabilitation program (CoTras) for recovering the memory and Electroencephalogram (EEG) activity in stroke patients.
Methods : A single-subject multiple-baseline experiment research design was used to determine the effect of Cognitive Training System (CoTras). Three participants who have had memory deficit post-stroke were trained using CoTras for 30 minutes per session. A total of twenty sessions were conducted. Their EEG was recorded during each session, and their relative power spectrum was analysed based on the beta/theta ratio. A Digit Span Test (DST) of the Computerized Neurocognitive Function Test (CNT) was used to assess the memory of each subject during each session, and Loewenstein Occupational Therapy Cognitive Assessment-Geriatric (LOTCA-G) was used to evaluate their brain activation pre- and post-test. The data were visually analyzed using graphs and a descriptive statistical analysis.
Results : All of the participants showed a significant increase in memory, and their LOTCA-G and DST scores were improved post-test. However, no significant changes in EEG were shown.
Conclusion : These findings provide evidence that CoTras is an effective approach to memory recovery after a stroke; however, their EEG levels did not change.
