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.
