Immersive virtual reality rehabilitation improved dynamic balance, motor function, and quality of life in Parkinson's disease patients.

This systematic review and meta-analysis evaluated the effectiveness of fully immersive virtual reality or immersive virtual environment rehabilitation compared to conventional treatment in individuals with Parkinson's disease. Data were pooled from 13 studies included in the analysis. The primary outcomes assessed included dynamic balance measured by the Timed Up and Go Test, motor function assessed via the Unified Parkinson's Disease Rating Scale, and quality of life measured by the Parkinson's Disease Questionnaire-39. Secondary outcomes included static balance, the Tinetti scale, falls efficacy, and cognitive performance.

The analysis found that fully immersive virtual reality rehabilitation resulted in significantly improved dynamic balance, motor function, and quality of life compared to conventional treatment. Conversely, the review reported no significant changes for static balance, the Tinetti scale, the Falls Efficacy Scale-International, or cognitive performance. Specific effect sizes, absolute numbers, and p-values were not reported in the source data.

Safety and tolerability data were not reported for adverse events, serious adverse events, discontinuations, or general tolerability within the included studies. A key limitation identified was high heterogeneity for quality of life outcomes, with an I2 greater than 50%. The authors emphasize the need for future randomized controlled trials with larger samples and extended follow-up to address these gaps.

The practice relevance suggests that rehabilitation integrating fully immersive virtual reality may be more effective than conventional treatment for specific functional domains in Parkinson's disease. However, clinicians should interpret these findings cautiously given the heterogeneity and lack of detailed statistical reporting. The evidence does not support claims of benefit for static balance or falls efficacy based on this review.
