目的：使用近红外光谱技术监测运动和运动想象时大脑血氧反应的变化以探讨运动和运动想象运用于脑卒中偏瘫患者康复治疗和评价的理论依据。
方法：选取64名健康大学生，随机分为两组：运动组32名，运动想象组32名。运用近红外光谱技术监测运动组受试者安静时和运动时大脑皮质的血氧代谢相应变化情况，以及运动想象组受试者安静时和运动想象时大脑皮质的血氧代谢相应变化情况，并将监测结果进行统计学比较和分析。
结果：①运动时，大脑氧合血红蛋白和总血红蛋白明显增加，而还原血红蛋白下降。②运动想象时，也呈现大脑氧合血红蛋白和总血红蛋白增加，而还原血红蛋白下降。与安静时进行比较，差异均有显著性意义。
结论：运动想象与实际运动同样会提高大脑皮质血氧饱和度，改善相应区域大脑皮质血氧供应。 |

| Abstract
Objective: To monitor the changes of cerebral blood oxygen reactions during movement and motor imagery with near infrared spectroscopy, to explore the theoretical basis of movement and motor imagery used in rehabilitation of patients with cerebral-vascular accident.
Method: Sixty-four healthy college students were randomly divided into two groups: movement group and motor imagery group. Near infrared spectral technology was used to monitor the cerebral cortex cerebral blood oxygen metabolism during quiet and movement or motor imagery in both groups and the monitor results were compared and statistically analysed.
Result: ①During movement oxy-Hb and total-Hb increased significantly, while deoxy-Hb decreased obviously. ②During motor imagery oxy-Hb and total-Hb increased, and deoxy-Hb decreased also. Compared to during quiet the monitor results during movement and motor imagery were statistically significant different.
Conclusion: Motor imagery and exercises can efficiently cause increasing of blood oxygen saturation of cerebral cortex and improve the corresponding regional cerebral blood oxygen supply. |
