皮质肌肉相干的影响因素及康复应用

Cortico-muscular coherence (CMC) is a tool for understanding how the cerebral cortex controls muscle movement and for evaluating the functional coupling between the motor cortex of the brain and related muscles, and it is of great significance in relevant research on rehabilitation assessment. Starting from the definition of CMC, the frequency distribution characteristics of CMC in three main frequency bands such as α, β and γ are summarized; from the perspective of theoretical research, the effects of factors such as force level, age and pathological state on CMC are summarized; in terms of the application research of CMC, its application in the rehabilitation of stroke and other patients with movement disorders is emphasized. Finally, some limitations in CMC research are discussed, and at the same time, improvements and exploration directions for the subsequent development of CMC are proposed, hoping to provide new perspectives and means for relevant rehabilitation research.

皮质肌肉相干（CMC）是了解大脑皮质如何控制肌肉运动,以及评估大脑运动皮层与相关肌肉之间功能耦合的一种工具,在康复评估的相关研究中具有重要意义。从CMC的定义出发,概括了CMC在α、β与γ等3个主要频带的频率分布特征;从理论研究的角度,总结了作用力水平、年龄和病理状态等因素对CMC的影响;在CMC的应用研究方面,着重介绍了其在脑卒中以及其他运动障碍类患者康复中的应用。最后论述了有关CMC研究中的一些局限性,同时就CMC的后续发展提出了可改进与探索之处,以期为相关的康复研究提供新的视角和手段。
