Effects of virtual reality on balance in people with diabetes: a systematic review and meta-analysis.

Purpose: This systematic review aims to identify, critically appraise, and synthesize the effects of virtual reality on balance in people with diabetes.

Methods: Five biomedical databases were searched from inception to December 15, 2023. Clinical trials investigating the effects of virtual reality on performance-based or patient-reported outcome measures related to balance function among people with diabetes were included. Two independent reviewers conducted study selection, data extraction, and quality assessment. Cochrane risk-of-bias tool-2 were used to assess included studies. Meta-analysis was performed to examine the effects of the intervention.

Results: Six studies with a total of 257 participants were identified. Two studies had high risk of bias, and four studies had some concerns regarding risk of bias. No adverse events related to virtual reality were reported. Meta-analysis revealed significant improvements in the Berg Balance Scale (SMD = 1.56, 95% CI 0.71 to 2.40,  < 0.001), Timed Up and Go test (SMD = -0.74, 95% CI -1.21 to -0.28,  = 0.002), and falls efficacy (SMD = 0.99, 95% CI 0.43 to 1.54,  < 0.001) following virtual reality intervention. No significant differences were found for postural sway and single leg stance measures.

Conclusion: Virtual reality-based rehabilitation demonstrates promising effects for improving balance in people with diabetes. Further studies with high methodological quality and large sample sizes are warranted.
