摘要:

双上肢抬起运动常见于大脑康复干预中,但未见关于这些运动对大脑皮质影响的报道。因而我们应用功能性近红外光谱技术观察10例健康人双上肢抬起运动过程中皮质激活情况。结果发现,双上肢抬起运动过程中初级感觉运动皮质,前运动皮质,辅助运动区和前额叶皮质中的氧合血红蛋白和总血红蛋白含量相近,均高于后顶叶皮质。由此说明,双上肢抬起运动诱发大面积大脑皮质神经元激活,从而有助于大脑功能的恢复。

Abstract:

Bilateral arm raising movements have been used in brain rehabilitation for a long time. However, no study has been reported on the effect of these movements on the cerebral cortex. In this study, using functional near infrared spectroscopy (fNIRS), we attempted to investigate cortical activation generated during bilateral arm raising movements. Ten normal subjects were recruited for this study. fNIRS was performed using an fNIRS system with 49 channels. Bilateral arm raising movements were performed in sitting position at the rate of 0.5 Hz. We measured values of oxyhemoglobin and total hemoglobin in five regions of interest: the primary sensorimotor cortex, premotor cortex, supplementary motor area, prefrontal cortex, and posterior parietal cortex. During performance of bilateral arm raising movements, oxyhemoglobin and total hemoglobin values in the primary sensorimotor cortex, premotor cortex, supplementary motor area, and prefrontal cortex were similar, but higher in these regions than those in the prefrontal cortex. We observed activation of the arm somatotopic areas of the primary sensorimotor cortex and premotor cortex in both hemispheres during bilateral arm raising movements. According to this result, bilateral arm raising movements appeared to induce large-scale neuronal activation and therefore arm raising movements would be good exercise for recovery of brain functions.
