運動練習側の反対側でおこなうリラックスイメージが脊髄前角細胞の興奮性変化に与える影響

Abstract

<p>To clarify the effects of relaxation imagery on spinal motoneuron excitability, changes in the excitability ofspinal motoneurons were examined using F-waves during imagery of the sensation of weakness in the nondominanthand converted to the dominant hand. Twenty healthy participants recruited in the study. After resting for 3 minutes, F-waves were measured with the dominant hand (resting trial). F-waves during an exercise task with the non-dominant hand were measured in the dominant hand (exercise task trial). F-waves were measured in the dominant hand during a verbally instructed relaxation imagery task (imagery trial). The results show that there were no differences in the F/M amplitude ratios and frequencies between the resting and imagery trials, but there were differences between individuals. Relaxation imagery without an imagery strategy did not decrease spinal motoneuron excitability, but many cases of decrease were observed among the individuals, suggesting the importance of specifying the imagery strategy and imagery content.</p>
