摘要:

目的 探究静息状态下,下肢截肢患者脑电信号在多频段上脑功能连接的变化。方法 2020年11月至2021年6月,采集22例健康成年人(对照组)和18例下肢截肢患者(患者组)静息态脑电图,以相位锁值构建功能连接矩阵,比较两组间差异。结果 患者组α频段(t = 3.433, P = 0.001)和β频段(t = 3.806, P = 0.001)功能连接明显减弱,δ频段(t = 1.429, P = 0.161)和θ频段(t = 1.211, P = 0.233)功能连接与对照组无显著性差异。结论 下肢截肢患者脑电α、β频段功能连接减弱,导致多个脑区功能重塑,包括相关肢体投射脑区、额叶、颞叶、枕叶等。

Abstract:

Objective To investigate the changes of functional brain connectivity over multiple frequency bands in resting-state electroencephalography (EEG) for lower limb amputation patients. Methods Resting-state EEG was collected from 18 lower limb amputees and 22 healthy controls from November, 2020 to June, 2021. Functional connectivity matrix was constructed with phase-locked values (PLV), and compared between groups. Results The functional connectivity was weaker in the amputees than in the controls on α band (t = 3.433, P = 0.001) and β band (t = 3.806, P = 0.001), and there was no significant difference on δ band (t = 1.429, P = 0.161) and θ band (t = 1.211, P = 0.233). Conclusion EEG functional connectivity weakens in lower limb amputees in on the α and β band, which results in neuroplasticity of multiple brain regions, not only for limb-respond cortex, but also for frontal, temporal and occipital cortices.

Key words: lower limb, amputation, resting-state electroencephalography, functional connectivity, phase-locked values
