Dance Exergames for Older Adults: A Systematic Review and Meta-Analysis With Narrative Synthesis.

BACKGROUND: A systematic review and meta-analysis with narrative synthesis was conducted to evaluate the impact of dance exergaming on older adults' health-related outcomes and its feasibility, usability, and safety. METHODS: PubMed, Scopus, CINAHL, Web of Science, The Cochrane Library, ProQuest Dissertations and Theses Global, and Google Scholar were searched from inception to December 7, 2023. Interventional studies using immersive or nonimmersive virtual reality platforms conducted on older adults ≥60 years old were eligible. Meta-analysis was conducted using the random effects model by pooling mean differences (MD) or standardized mean differences. Outcomes were narratively synthesized when meta-analysis was not possible. RESULTS: Forty-three articles from 37 studies were included (n = 1 139 participants at baseline). Postintervention, dynamic balance measured using Berg Balance Scale (pooled MD = 2.65, 95% CI: 1.73-3.57, p < .0001), Timed-Up-and-Go times (pooled MD = -1.04, 95% CI: -2.06 to -0.03, p = .04), choice stepping reaction time (pooled MD = -92.48, 95% CI: -167.30 to -17.67, p = .02), and movement time (pooled MD = -50.33, 95% CI: -83.34 to -17.33, p = .003) were significantly better in the experimental group compared to the control group. Adherence ranged from 76.5% to 100%, whereas attrition ranged from 9.1% to 31.9%. Most participants completed the intervention with no or minimal adverse effects. CONCLUSIONS: Dance exergames are effective, feasible, usable, and safe for older adults. Further research is needed as the findings were limited by small sample sizes. Many studies could not be included in the meta-analysis as outcomes were too varied.
