The aim of this study were to investigate the effects of a 4-week short foot exercise (SFE) program on abductor hallucis (AbdH) activity, static balance, and dynamic balance in people with neutral feet (NF) and flexible flat feet (FF), compare the effects between NF and FF, and confirm correlations between AbdH activity and balance. A total of 24 subjects participated in this study (12 with FF and 12 with NF). AbdH activity was measured using surface electromyography, static balance [center of pressure (COP) sway area and speed] was measured using a force plate, and dynamic balance was measured using the star excursion balance test (SEBT) score. The paired t-test was used to investigate SFE effects, the analysis of covariance to investigate group differences, and the Pearson‟s correlation coefficient to investigate relationships. Both groups exhibited significantly improved AbdH activity and static and dynamic balance. Significant group differences were observed in AbdH activity and COP sway area but not in COP speed and SEBT score. Moderate correlations were observed between AbdH activity and static balance but not dynamic balance. These results demonstrate that the 4-week SFE program improved foot intrinsic muscle activity and balance in both people with NF and FF. Therefore, SFE may be considered as an effective exercise for FF as well as rehabilitation for people with ankle instability
