초록

Purpose: This study compared and analyzed the contractility of the abductor hallucis (AbdH), an intrinsic foot muscle, between flat feet and normal feet during a movement control test (single-leg small knee band test) using ultrasonography. Methods: A total of 23 subjects with (n = 11) and without (n = 12) flatfoot were included in the study. Each subject performed the short foot exercises (SFE) with a single-leg small knee bend (SLSKB) test, which is a functional movement. An ultrasound device was used to collect data regarding the changes in the contractility of the AbdH. Results: Intergroup comparison showed that dorsoplantar thickness was significantly reduced at baseline and during the SFE with SLSKB in the flatfoot group (p < 0.05). Intragroup comparison showed that the cross-sectional area significantly improved when the SFE was performed with SLSKB in the control group (p < 0.05). Conclusion: In this study, it was observed that the AbdH had inadequate contractility during the SLSKB test in subjects with flatfoot; therefore, it is important to train the contraction of the AbdH via functional movements during clinical interventions for subjects with flatfoot.
