Abstract

<p>In this study, we examined the influence of differences in motor image ability on the spinal neural function in motor imagery tasks of oppositional movements between the thumb and the other four fingers. A total of 30 healthy volunteers (17 males and 13 females; mean age, 24 ± 5 years) participated in this study. The subjects’ motor image abilities were evaluated using the Movement Imagery Questionnaire Revised Japanese Version (JMIQ-R), and they were divided into high and low motor image ability groups using the median of their JMIQ-R scores. Motor imagery of the oppositional movement between the thumb and the index finger (task 1), the thumb and middle finger (task 2), the thumb and ring finger (task 3), and the thumb and little finger (task 4) was recorded. Each task was carried out at a frequency of 1 Hz for 1 minute. The relative value of the F / M amplitude ratio increased significantly in task 4 in the group with low motor image ability compared to tasks 1 and 2. This suggests that the excitability of the spinal neural function may have increased more in the group with low motor image ability when motor imagery of oppositional movement between the thumb and little finger was performed compared to that of the index and middle fingers.</p>
