Correlation between the body balance and functional capacity from elderly with chronic vestibular disorders

ABSTRACT: Vestibular disorders are common among the elderly, mainly resulting in dizziness and imbalance - symptoms which can impact daily routine activities. AIM: To study the correlation between body balance and functional capacity and a comparison of risk of falls, actual falls and the functional capacity of the elderly with chronic vestibular dysfunctions. MATERIALS AND METHODS: A cross-sectional, clinical and experimental study with 50 senior citizens - 60 to 86 years, with chronic peripheral vestibular dysfunction. These participants underwent body balance assessment by the Dynamic Gait Index (DGI) and functional capacity assessment by the Functional Independence Measure (FIM). The data was tested using the Spearman correlation and comparison tests, Mann-Whitney and Kruskal- Wallis, being α=5% (0.05). RESULTS: There was a significant correlation between the total DGI score and all FIM scores, especially the total score (r=0.447; p<0.001) and loss of functional capacity in elderly patients with the highest risk of falling (p<0.001). CONCLUSION: There is a positive correlation between body balance and functional capacity in elderly patients with peripheral vestibular disorders, that is: the better the balance, the better the individual's functional capacity. In addition, a worse functional capacity increases the individual's risk of falling.
