Efficacy of computerized cognitive training on improving cognitive functions of stroke patients: A systematic review and meta-analysis of randomized controlled trials.

AIM

To evaluate the effects of computerized cognitive training on the cognitive functions of stroke patients.

BACKGROUND

With increased publications on computerized cognitive training, a meta-analysis is essential to determine the effects of computerized cognitive training among stroke patients.

DESIGN

A systematic review and meta-analysis of randomized controlled studies.

DATA SOURCES

Cochrane Library, Pubmed, EBSCO, Scopus, China National Knowledge Infrastructure, China Biology Medicine disc and Wanfang Database were explored to search for research studies from inception to January 2020.

REVIEW METHODS

Six outcomes indicators were considered to determine the effects of computerized cognitive training. Two reviewers were selected to search and independently appraise the available articles from various databases. Meta-analysis was performed using the RevMan 5.3 software.

RESULTS

A total of 622 patients with 17 studies were included. Computerized cognitive training significantly improves global cognition, working memory, attention and executive function of stroke patients. However, there was inadequate evidence to demonstrate any effects of computerized cognitive training on activities of daily living and depression.

CONCLUSION

Computerized cognitive training improves the cognitive functions of stroke patients. However, further research studies are needed to confirm its efficacy in activities of daily living as well as on alleviating depression.
