摘要:

目的 探究老年人完成平衡控制任务的脑网络特征。方法 2022年1月至4月,于广州医科大学附属第五医院和社区招募22例健康年轻人和20例健康老年人,两组站在足底压力测试板上,完成睁眼或闭眼站立任务,功能性近红外光谱测量左、右前额叶皮质(PFC)和初级运动区(PMC)功能连接强度。结果 老年人闭眼状态下的椭圆面积(Z = -2.884, P < 0.01)和最大摆动范围(Z = -2.481, P < 0.05)大于年轻人;站立任务时,老年人左侧(t = 2.978, P < 0.01)和右侧PFC(Z = -3.123, P < 0.01)内部功能连接降低;右PMC-左PFC (t = 2.087, P < 0.05)和右PFC-左PFC (t = 3.471, P < 0.001)间功能连接降低。结论 与年轻人相比,老年人在平衡控制任务中出现PFC功能连接降低,可能与早期脑老化有关。

Abstract:

Objective To study the brain network during balance control tasks in older adults. Methods From January to April, 2022, 22 healthy young adults and 20 healthy older adults were recruited from the Fifth Affiliated Hospital of Guangzhou Medical University and communities. They were asked to finish standing tasks on the plantar pressure plate with eyes opening and closing, while the functional connectivities (FC) of prefrontal cortex (PFC) and primary motor cortex (PMC) were measured with functional near-infrared spectroscopy. Results Compared with the young adults, the area of the ellipse (Z = -2.884, P < 0.01) and the maximum swing (Z = -2.481, P < 0.05) increased in the older adults as eyes closing. During the standing task, the intra-FC of left (t = 2.978, P < 0.01) and right (Z = -3.123, P < 0.01) PFC decreased in the older adults, and the inter-FC of right PMC to left PFC (t = 2.087, P < 0.05) and right PFC to left PFC (t = 3.471, P < 0.001) decreased, too. Conclusion The FC of PFC decreased in healthy older adults during balance control tasks, which may be a indicator for aging brain.

Key words: older adults, aging brain, balance control, functional near-infrared spectroscopy, functional connectivity, prefrontal cortex
