  • Objective: To determine if single-leg balance performance differs among individuals of different foot types using time-to-boundary (TTB) and Star Excursion Balance tests (SEBT). And to determine if there is a relationship between Foot Posture Index-6 (FPI-6) scores, TTB mean minima and SEBT scores. Subjects: 61 total subjects; 20 supinated, 21 neutral, 20 pronated. Measurements and Data: FPI-6 was used to classify foot type. TTB measurements in the medial/lateral and anterior/posterior direction were evaluated. SEBT maximum reach scores in the anterior, posteromedial, and posterolateral directions were also evaluated. Nine separate one-way ANOVAs, and a correlation matrix were used for statistical analysis. Results: A significant difference was found between pronated and neutral foot type for TTB mean minima in the medial/lateral direction. No significant differences were found between foot type for any other dependent variable. No significant relationships were discovered between FPI-6, SEBT, and TTB scores. Discussion: Pronated feet demonstrated better balance performance than neutral feet in the frontal plane, possibly due to a wider base of support. The SEBT and TTB scores have no relationship, thus measuring different aspects of balance performance.
