Abstract
The purpose of this study was to investigate the relation between fall and performance under multiple-task condition. Subjects were 30 elderly people (12 faller and 18 non-faller). The motor performance when changing the difficulty of a gradual short-term memory task was evaluated. The relation between the difficulty of a task and ease of a fall was investigated using two-way analysis of variance. By the fall group, when the difficulty of the short-term memory task increased, the motor performance decrease. However, by the non-fall group, the motor performance was maintained regardless of the difficulty of a short-term memory task. These results suggested that short-term memory under multiple-task condition had influenced the fall in elderly people.
