[Purpose] This study aimed to compare dynamic balance ability according to foot shape,
defined as normal, pronated, or supinated on the basis of the height of the medial arch.
[Subjects] In this study, 14 subjects for the pronated foot group, 14 for the supinated
foot group, and 14 for the normal foot group were selected from among 162 healthy
university students by using the navicular drop test proposed by Brody. To measure dynamic
balance ability, a star excursion balance test (SEBT) was conducted for each group, in
which a cross-shaped line and lines at 45° in eight directions were drawn on the floor. In
this study, only three directions were used, namely anterior, posterolateral, and
posteromedial. The mean of the SEBT was calculated by measuring three times for each
group, and the values were standardized using the following equation: measured value/leg
length × 100. [Results] No significant differences in dynamic balance ability were found
between the normal, pronated, and supinated foot groups. [Conclusion] No significant
differences in dynamic balance ability according to the foot shape were found among the
healthy university students with normal, pronated, and supinated feet.
