운동역학 : 노인의 트레드밀 보행시 속도에 따른 보행 패턴의 변화 연구 = The effect of the speed conditions on the gait pattern in treadmill walking of eldery persons

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effect of speed conditions on the gait pattern in treadmill walking of old age. Data were collected by 3d cinematography and video analyzing system. Six male eldery persons were participated in this experiment All subjects performed a walking activity with slow(3.5㎞/h), moderate(4.0㎞/h), fast(4.5㎞/h) speed conditions on treadmill with 10% grade. The changes of lower extremity angles were analyzed during one stride. One-way ANOVA was used to evaluating the statistical significance. The results obtained from this study were as follows:1. The stance phase was decreased and swing phase was increased as the speed of treadmill was increased in all subjects. But there was no significant difference statistically.2. All subjects did not show a significant difference in speed conditions of treadmill at major events in mean ankle angle. However, max. ankle angle and ROM(range of motion) during stance phase was augmented as the speed was increased(P＜.05).3. All subjects did not show a significant difference in speed conditions of treadmill at major event in mean knee angle. However, min. ankle angle during stance phase and ROM during swing phase was augmented as the speed was increased(P＜.05).
