  • Objective: To test the fatigue related effects of ankle bracing on time to boundary measurements between healthy and chronically unstable participants. Data and setting: A pre-test post-test experimental design was used to compare the effects of ankle bracing and fatigue on time to boundary measures with chronic ankle instability and control subjects. Subjects: 38 physically active subjects; 19 subjects with chronic ankle instability, and 19 subjects to serve as controls. Measurements: Time to boundary measurements in the medial/lateral and anterior/posterior direction were evaluated. A three way mixed model analysis of variance was used for statistical analysis. Results: A Significant three way interaction was found in the eyes closed condition. Significant two way interactions were found for bracing by group for eyes open, and significant two way interactions were found in the eyes closed condition for bracing by fatigue. Significant main effects were found for bracing and fatigue in both eyes open and eyes closed conditions. Discussion: There were no differences between CAI and healthy control participants on TTB measurements. The no braced condition proved to be more stable than the braced condition, as well as post-fatigue proving more stable than pre-fatigue.
