운동역학: 자세 유지의 발달적 조절 전략에 대한 연구 = The Study of Development Control Strategy in postural Maintenance

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze postural control strategy with age. Posturography was used of sensory organization test and motor control test in various environmental conditions. Each 10 subjects participated in the experiment among children, adults, and elderly people. In the sensory organization test, the results revealed that the postural stability appeared to be stable in the order of adults, ederly people, and children. Also, all groups showed different postural control strategies according to the platform movement. In the analysis of sensory ratio, the somatosensory ratio revealed no differences among three groups. However, there were significant differences in visual ratio and vestibular ratio with age. Especially, visual ratio and vestibular ratio of children group were less than those of adults and ederly groups. In the results of the motor control test, the delay of the reaction time and decrement of the response strength were shown to be an important factor of postural control problem in the elderly group.
