노인대상 12주간 균형능력 향상 운동이 계단 내리기 보행 시 주요 관절각 및 지면반력 변화에 미치는 영향 = The Effects of 12 Week Balance Ability Improvement Exercise to the Changes of Selected Joint Angles and Ground Reaction Forces dur ing Down Staircase Walking

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effects of balance ability improvement exercise program which applied to the elderly people for increasing balance, stability and range of motion. Ten elderly people and ten university students were recruited as the subjects. Kinematic data were collected by seven real-time infrared cameras while subjects walk stair descent as a pre-test. Korean folk dance exercise program was applied to the elderly for 12 weeks. Same experiment on stair descent walk was performed as post-test. Results indicated that CM movement and selected joint angle patterns of elderly group after treatment changed to the similar patterns of young group. However, ankle joint angle and vertical GRF of elderly group after treatment also increased compared to those of the elderly group before treatment. This might be explained by the fact that elderly used a different walking strategy which maximize support base for increasing stability. Overall, these results indicated that the exercise treatment may affect to adapt and improve the gait pattern of stair descent of elderly people.
