Purpose: Postural stability has an important role for developing locomotion skills, especially in childhood. The purpose of this study was to investigate the developmental change of postural stability with respect to locomotor skills. Methods: Thirty-five participants aged between five to seven year-old whom differentiated by pre examination were divided into Jumping, Hopping, Galloping and Skipping group, respectively. They were asked to perform quiet standing and leaning voluntarily forward, backward, left and right as far as possible on a force plate. A vector of center of pressure was measured to calculate postural stability and one-way ANOVA was performed. Results: Jumping group showed significant low postural stability than the others and there is no significant difference among Hopping, Galloping, and Skipping group who can perform advanced locomotor skills. Conclusion: Postural stability seems to increase when children acquire advance locomotor skills and this result might reflect nonlinear characteristic of human motor development.
