[Purpose] This study examined possible interrelationships between postural sway and posture parameters in children and adolescents with a particular focus on posture weakness. [Subjects and Methods] 308 healthy children and adolescents (124 girls, 184 boys, aged 12.3 ± 2.5 years) participated in the study. Posture parameters (posture index, head protrusion, trunk inclination) were determined based on posture photos in the sagittal plane. Postural sway was measured during 20 seconds on a force plate. The Pearson's product-moment correlation coefficients between the anthropometric and posture parameters and the sway path length (SPL) were calculated, as well as the coefficient of determination R. [Results] There is a weak but significant correlation between age or body mass index of the test subjects and the SPL. There is no statistically significant correlation between posture parameters and the SPL. Children and adolescents with posture weakness do not exhibit a changed SPL. [Conclusion] Therefore, therapy of poor posture must be considered separately from therapeutic measures for the improvement of balance skills.
[目的] 本研究探讨了儿童和青少年姿势摇摆与姿势参数之间可能存在的相互关系，特别关注姿势薄弱情况。[对象与方法] 308名健康儿童和青少年（124名女孩，184名男孩，年龄12.3±2.5岁）参与了本研究。姿势参数（姿势指数、头部前突、躯干倾斜度）基于矢状面的姿势照片确定。在测力板上测量20秒内的姿势摇摆。计算人体测量参数和姿势参数与摇摆路径长度（SPL）之间的Pearson积矩相关系数，以及决定系数R。[结果] 测试对象的年龄或体重指数与SPL之间存在微弱但显著的相关性。姿势参数与SPL之间无统计学显著相关性。姿势薄弱的儿童和青少年并未表现出SPL的改变。[结论] 因此，姿势不良的治疗必须与改善平衡技能的治疗措施分开考虑。
