Background: Impaired movement after stroke is closely associated with altered brain functions, and thus the investigation on neural substrates of patients with stroke can pave a way for not only understanding the underlying mechanisms of neuropathological traits, but also providing an innovative solution for stroke rehabilitation. The objective of this study was to precisely investigate altered brain functions in terms of power spectral and brain network analyses.

上肢运动过程中α和低β带功能网络的改变及其与慢性中风运动障碍的关系

背景：中风后运动障碍与脑功能改变密切相关，因此对中风患者神经基质的研究不仅可以为理解神经病理特征的潜在机制铺平道路，而且可以为中风康复提供创新的解决方案。这项研究的目的是通过功率谱和大脑网络分析来精确研究大脑功能的改变。
