The Effect of Visual Feedback on Balance Rehabilitation in People with Impaired Ankle Instability: A Systematic Review and Meta-Analysis

Abstract Aim: The aim of this systematic review and meta-analysis was to(1) comprehensively assess the possible effects of visual feedback on balance exercise in a population with ankle instability;(2) Quantify the effects of visual feedback on balance in a population with ankle instability. Methods: A total of 10 studies were included in this systematic evaluation and Meta-analysis. This review was performed by the PERSiST (implementing Prisma in Exercise, Rehabilitation, Sport medicine and SporTs science) guidance. Four databases were searched and the research had to be written in English and involve the provision of visual feedback during balanced rehabilitation. Results: Visual feedback improves balance rehabilitation effects. Improvement of static balance, dynamic balance, and balance perception during balance exercise. The provision of visual feedback simultaneously increased subjective motivation to train and increased satisfaction and enjoyment of rehabilitation training. The results demonstrated that visual feedback improved the Foot and Ankle Ability Measure by approximately 17%(g=2.42,95%CI=0.72-4.12,I2[total]=0%).Also by providing visual feedback during the training cycle, the star excursion balance test(SEBT) may be positively affected(g=4.83,95%CI=3.09-6.56,I2[total]=21%). Also the biodex system's performance on measures of balance will be highly improved(g=0.14,95%CI=0.01-0.28,I2[total]=24%). Conclusion: Providing visual feedback in balance rehabilitation can produce beneficial adaptations to balance in individuals with ankle instability. The research included in our analysis demonstrates the positive impact of visual feedback, with almost all results showing better outcomes than when visual feedback is not provided.Visual feedback can be used as an "additive" or alternative to traditional rehabilitation for people with ankle instability.
