RELATIONSHIP BETWEEN POSTURAL SWAY AND BODY BALANCE WITH DEVELOPMENT OF WALKING MOTION IN CHILDHOOD

本研究旨在了解儿童行走运动质量的变化，并分析儿童体位摇摆和身体平衡与纵向发展的关系。最后，41名儿童（男孩23名，女孩18名）具有纵向发展分析所需的所有测量项目。实验结果如下：这些测量值的变化产生了体位摇摆（重心距离等）和身体平衡（闭眼站立平衡、平衡木行走）项目随年龄的显著发展，即被试从二年级到三年级一直保持稳定的站立位置。三年级男生弓形组的测量值明显高于弓形组的测量值。在不考虑年龄和性别的情况下，姿势摇摆的模式被分为“全身”型和“跷跷板”型。但随着年龄的增长，这些类型有向“中心”类型转变的趋势。发育的步行运动以步行速度分类，一年级和二年级的步行速度更快。身体各点的运动（膝盖角度、步幅等）随年龄的不同而不同，特别是在二年级和三年级之间。

The purposes of this study were to clarify the changes of quality in walking motion, and to analyze relationships between postural sway and body balance with longitudinal development in childhood. Finally, the subjects were forty-one children (twenty-three boys and eighteen girls) with all measurement items needed to analyze longitudinal development. The results were as follows ; The changes of these measurement values were produced the remarkably developments with age in items of postural sway (distance of center of gravity etc.) and items of body balance (standing balance with closed eyes, walking on balance beam), i.e. the subjects were held the stable standing position from second to third grade. In third grade boys, measurement values of arch formed group were remarkably developed than measurement values of arch non-formed group. The patterns of postural sway were classified "all over" type or "seesaw" type without regard to age or sex. But there was tended to changed from these types to "central" type with regard to age. The walking motion of development were classified with walking speed, the walking speed was faster between first grade and second grade. The motions of points on body (knee angle, stride etc) were differed with regard of age, particularly between seoond grade and third grade.
