Abstract

Background. Imagined motor movement is a cognitive process in which a subject imagines a movement without doing it, which activates similar brain regions as during actual motor movement. Brain gamma band activity (GBA) is linked to cognitive functions such as perception, attention, memory, awareness, synaptic plasticity, motor control, and Imagination. Motor imagery can be used in sports to improve performance, raising the possibility of using it as a rehabilitation method through brain plasticity through mirror neurons. Method. A comparative observational study was conducted on 56 healthy male subjects after obtaining clearance from the Ethics Committee. EEG recordings for GBA were taken for resting, real, and imaginary motor movements and compared. The power spectrum of gamma waves was analyzed using the Kruskal-Wallis test; a p-value <.05 was considered significant. Results. The brain gamma rhythm amplitude was statistically increased during both actual and imaginary motor movement compared to baseline (resting stage) in most of the regions of the brain except the occipital region. There was no significant difference in GBA between real and imaginary movements. Conclusions. Increased gamma rhythm amplitude during both actual and imaginary motor movement than baseline (resting stage) indicating raised brain cognitive activity during both types of movements. There was no potential difference between real and imaginary movements suggesting that the real movement can be replaced by the imaginary movement to enhance work performance through mirror therapy.

将实际运动和想象运动时伽马带活动的频谱分析作为一种认知工具进行比较。
背景介绍想象运动是一种认知过程,受试者在不做动作的情况下想象一个动作,这会激活与实际运动时相似的大脑区域。大脑伽马带活动(GBA)与感知、注意力、记忆、意识、突触可塑性、运动控制和想象等认知功能有关。运动想象可用于体育运动,以提高运动成绩,并有可能通过镜像神经元的大脑可塑性将其用作一种康复方法。研究方法在获得伦理委员会批准后,我们对 56 名健康男性受试者进行了比较观察研究。对静息、真实和想象的运动动作进行脑电图记录并进行比较。使用 Kruskal-Wallis 检验分析了伽玛波的功率谱;P 值 结果。据统计,与基线(静息阶段)相比,在实际运动和想象运动时,除枕叶区外,大部分脑区的脑伽马节律振幅都有所增加。实际运动和想象运动之间的伽马节律无明显差异。结论与基线(静息阶段)相比,实际运动和想象运动时的伽马节律振幅都有所增加,这表明这两种运动时大脑的认知活动都有所提高。实际运动和想象运动之间没有潜在的差异,这表明可以通过镜像疗法用想象运动代替实际运动来提高工作表现。
