Abstract
[Purpose] In this study, we investigated the memory recall ability of motor image at different ages using mental rotation. In addition, the relation between motor image and falls was also investigated in elderly people. [Subjects] The subjects were 333 healthy people aged between 20 and 86. [Methods] The reaction time of the mental rotation of the hand and foot was recorded. For elderly people, we conducted a follow-up investigation as to whether the subjects fell in the year following the measuring day. [Results] Almost all reaction times were extended with the aging, and fallers' reaction times were extended more than these of non-fallers. [Conclusion] Motor imaging tends to become difficult with the aging. In elderly people with a high fall risk, motor imaging was even more difficult.
