摘要:

运动想象是一种实际未运动而只是想象运动的行为。通过重复性运动想象完成的精神训练可提高运动能力,而无需同时进行感官的输入或输出。研究纳入21名健康右利手志愿者,对其使用筷子进行自我进食活动与运动想象过程中大脑脑区激活进行观察;(1)自我进食活动任务包括用筷子进食腌黄瓜片的运动或进行相同活动的运动想象;(2)应用近红外光谱法检测受试者大脑8个感兴趣区,包括:前辅助运动区,辅助运动区,双侧前额叶皮质、前运动区和感觉运动皮质的氧合血红蛋白水平,以反映大脑脑区激活情况;(3)在运动执行过程中,左侧感觉运动皮质的平均氧合血红蛋白水平明显高于辅助运动区和左侧前运动区;与运动执行相比,运动想象期间辅助运动区和左侧前运动区有较高的氧合血红蛋白水平;(4)在运动执行和运动想象过程中,辅助运动区和前运动区的激活水平可能会受到有意认知的影响;(5)研究结果表明,在自我进食活动的运动执行和运动想象过程中,大脑8个感兴趣的激活水平不同。前运动区和辅助运动区在自我进食活动的运动想象中起重要作用。该研究于2018年12月10日获得长崎大学伦理审查委员会的批准(批准号18110801)。

Abstract: Motor imagery is defined as an act wherein an individual contemplates a mental action of motor execution without apparent action. Mental practice executed by repetitive motor imagery can improve motor performance without simultaneous sensory input or overt output. We aimed to investigate cerebral hemodynamics during motor imagery and motor execution of a self-feeding activity using chopsticks. This study included 21 healthy right-handed volunteers. The self-feeding activity task comprised either motor imagery or motor execution of eating sliced cucumber pickles with chopsticks to examine eight regions of interest: pre-supplementary motor area, supplementary motor area, bilateral prefrontal cortex, premotor area, and sensorimotor cortex. The mean oxyhemoglobin levels were detected using near-infrared spectroscopy to reflect cerebral activation. The mean oxyhemoglobin levels during motor execution were significantly higher in the left sensorimotor cortex than in the supplementary motor area and the left premotor area. Moreover, significantly higher oxyhemoglobin levels were detected in the supplementary motor area and the left premotor area during motor imagery, compared to motor execution. Supplementary motor area and premotor area had important roles in the motor imagery of self-feeding activity. Moreover, the activation levels of the supplementary motor area and the premotor area during motor execution and motor imagery are likely affected by intentional cognitive processes. Levels of cerebral activation differed in some areas during motor execution and motor imagery of a self-feeding activity. This study was approved by the Ethical Review Committee of Nagasaki University (approval No. 18110801) on December 10, 2018.
