EFFECTS OF HIGH INSPIRATION DEMAND ON BALANCE AND FALL RISK INDEX IN ELDERLY

Abstract

Objective: Analyze the effect of high inspiratory demand on balance and risk of falling in the elderly. Methods: The participants performed the Modified Clinical Test of Sensory Interaction and Balance (m-CTSIB) on the Biodex Balance System (BBS) platform with increased respiratory demand and immediately after the test. m-CTSIB was performed under three conditions: baseline assessment with free breathing; with an increase in the inspiratory demand and after the end of the test. For data analysis, the Shapiro-Wilk test was performed using the Levene test, and Analysis of Variance for repeated measures (ANOVA). Results: Thirteen elderly men (73 ± 7.25 years) were selected in whom the maximum inspiratory pressure (PImax) was evaluated. In the m-CTSIB protocol, pre and during comparison showed significant differences in Eyes Open in firm and unstable surface and in Fall Risk. When these conditions were compared during and after the tests, there were significant differences in all conditions. When pre and after were compared, only the Eyes Closed unstable surface showed a significant difference. Conclusion: The overload in the inspiratory demand was able to cause changes in the balance variables, especially when the volunteer is exposed to overload.
