  • Development and validation of trip-induction system by using a treadmill

抄録

<p>Trip-related falls account for a significant proportion of falls in older adults, often resulting in serious injury. A highly accurate fall-risk evaluation method will be increasingly required in the aged society. For this purpose, it is necessary to measure more realistic motion against tripping. We developed a method to induce tripping at arbitrary walking distance and timing in the laboratory using a treadmill and evaluated the validity of it by measuring reaction motion. With respect to each joint angle, it does not greatly deviate from the result of the previous study in the walking lane, and its transition was similar. However, the transition of the forward moment after tripping was very different. By adjusting the treadmill acceleration condition at the same time as the obstacle collision, it would be possible to measure a more realistic motion against tripping.</p>
