Abstract
AIMS: The aim of this review is to synthesize and evaluate effectiveness of exergaming on balance, lower limb functional mobility and functional independence in individuals with chronic stroke. DESIGN: The present review is a systematic review and meta-analysis. The review is written in accordance with the guidelines from the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) DATA SOURCE: Searches were conducted across seven databases (PubMed, EMBASE, Web of Science, CINAHL, CENTRAL, Scopus and PEDro) and in grey literature from inception until January 2021. REVIEW METHODS: Only randomized controlled trials (RCTs) written in English were included. All eligible studies were assessed for risk of bias by two reviewers independently. Meta-analyses were performed using RevMan 5.4.1 software. Narrative syntheses were adopted whenever meta-analysis was inappropriate. The overall quality of evidence from included studies was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) framework. RESULTS: 4511 records were retrieved, with 32 RCTs eligible for inclusion and 27 RCTs included in meta-analysis. Meta-analyses reported statistically significant small effect sizes favouring exergaming on balance (pooled standardized mean difference [SMD] = 0.25, 95% confidence interval [CI, 0.08-0.41], p = .004), lower limb functional mobility (pooled SMD = 0.29, 95% CI [0.08-0.50], p = .007) and functional independence (pooled SMD = 0.41, 95% CI [0.09-0.73], p = .01). Most of the included studies failed to provide adequate description of the measures taken to prevent bias. CONCLUSION: Exergaming has favourable effects on improving balance, lower limb functional mobility and functional independence among individuals with chronic stroke, making it a suitable adjunct to conventional physiotherapy. IMPACT: People with chronic stroke have difficulty achieving the required rehab intensity. Exergaming can help individuals with chronic stroke to undertake further rehabilitation exercises at home. It can be a suitable adjunct to conventional physiotherapy.
