| Outline of Final Research Achievements |
We investigated the developmental changes in lateral dominance in single-leg stance stability during floor oscillations at various frequencies. Ten children aged 5 to 9 years maintained single-leg stance on a force platform for 20 s per trial. Trials were performed with no-oscillation (static condition) and with anteroposterior floor oscillations (2.5-cm amplitude) at six frequencies: 0.25, 0.5, 0.75, 1.0, 1.25, and 1.5 Hz (dynamic condition). The mean speed of the center of pressure in the anteroposterior direction (CoPap) and maximum duration maintaining the posture were calculated as an index of postural stability. In static and dynamic condition, there was no lateral dominance of stability during single-leg stance in children aged 5 to 9 years. Unlike previous studies of adults (Kiyota and Fujiwara, 2014), it was found that role in support function may not be divided between left and right legs according to the balance conditions in children aged 5 to 9 years.
