Objectives: This study aimed to compare the dynamic balance between flat feet and normal athletes using Star Excursion Balance Test (SEBT). Research Design: This was a Cross-sectional comparative study. Method: Total 58 athletes, 29 subjects with flat feet (assessed by Sit to Stand Navicular Drop Test) and 29 subjects with normal feet were selected. Both male and female athletes of age group 18-30 years were included. Sit to Stand Navicular Drop Test, Calcaneum Angle, the width of the foot, great toe extension range of motion and Stat Excursion Balance Test (SEBT) were the outcomes that were assessed in the study. Data analysis: Unpaired t-test using the Graph Pad Instat software system was used. Results: Significant mean differences in Sit to Stand Navicular Drop Test, Calcaneum Angle, the width of the foot, great toe extension range of motion, and SEBT were found in individuals with flat feet. The SEBT scores of normal arched feet (right leg: 75.50.2, left leg: 75.10.4) and flat feet (right: 78.12.3, left: 79.93.2) differed (p=0.001). The SEBT leg difference scores of subjects with flat feet (4.43.5) and normal arches (2.30.5) differed (p=0.001). Furthermore, the lateral excursion distance was the least in these individuals (p<0.0001). Conclusion: In flat feet individuals' Dynamic Balance is compromised as compared to normal arched feet.
