Abstract
- BACKGROUND: The abductor hallucis (AbH) is a key muscle in the stability of the foot by supporting the medial longitudinal arch (MLA). Individuals with flat foot show a flattening of the MLA with a decreased selective AbH activity relative to the other foot extrinsic muscles during functional movement. OBJECTIVE: To examine the selective muscle activity of the abductor hallucis (AbH) during single-leg mini-squat (SMS) in subjects with flat foot and normal individuals. METHODS: Twenty-four healthy adults (13 men and 11 women) with flat or normal feet participated in this study. All subjects performed single minisquat (SMS), and data were collected using sEMG from the AbH, TA, and GCM during SMS. RESULTS: An inter-gender comparison of the EMG data revealed no difference. The EMG activity of the AbH in individuals with flat foot was significantly lower than that of individuals with normal feet. Moreover, the AbH/TA ratio in subjects with flat foot, , was significantly lower than that in subjects with normal feet. CONCLUSION: In a clinical setting, clinicians should focus on strengthening exercises of the AbH muscle due to reduced activation of the AbH muscle in individuals with flat foot. The selective muscle activity of the AbH muscle during SMS should be emphasized. [ABSTRACT FROM AUTHOR]
