概要	The aim of this study was to investigate whether the performance of a combination of observation and motor imagery of chopstick use (complex task) increased corticospinal excitability more than the performance of ob-servation alone. We recruited 10 healthy sub-jects with no history of neurological diseases. Corticospinal excitability was assessed with the participants seated in front of a computer screen performing three tasks: (1) control, the subjects were instructed to relax; (2) OBS, the subjects were told to observe an action de-picted in the video, and (3) OBS + IMG, the subjects were told to imagine performing an action depicted in a video. During tasks (2) and (3), a video was displayed on the computer screen showing the hand of a male subject using chopsticks to move small items of food from one dish to another (first person per-spective). Imagery was performed kinestheti-cally. The MEP amplitude in the first dorsal interosseous was significantly increased during OBS+IMG relative to that in the control con-dition, but not that in the OBS condition. The MEP amplitude in the thenar muscles was sig-nificantly different between OBS and OBS+IMG. These results suggest that the combination of observation and motor imagery of a complex task may be more effective than observation alone for motor rehabilitation purposes. 担当部分：全般 (corresponding author)
