Trip-related falls, which account for a significant proportion of falls in the elderly, often result in the serious injury. A highly accurate fall-risk evaluation method will be increasingly required in the aged society. For this purpose, it is necessary to observe more realistic reaction motion against tripping. Thus, we developed a method to induce tripping at arbitrary timing during walking in the laboratory using a treadmill and evaluated the validity of the method by analyzing the reaction motion. At the same time, another experiment, which induces trip in a walking lane, was conducted. Then, they were compared each other. In this study, the difference in sensory comfort rate between treadmill walking and ground walking was focused on. It is necessary to determine whether individual differences in response to trip-induction depends on what kind of conditions. It is considered to be either the experimental system and conditions, or the gait difference inherent to the subject.
