Stroke, also known as cerebrovascular accident, is an acute cerebrovascular disease with a high incidence, disability rate, and mortality. It can disrupt the interaction between the cerebral cortex and external muscles. Corticomuscular coherence (CMC) is a common and useful method for studying how the cerebral cortex controls muscle activity. CMC can expose functional connections between the cortex and muscle, reflecting the information flow in the motor system. Afferent feedback related to CMC can reveal these functional connections. This paper aims to investigate the factors influencing CMC in stroke patients and provide a comprehensive summary and analysis of the current research in this area. This paper begins by discussing the impact of stroke and the significance of CMC in stroke patients. It then proceeds to elaborate on the mechanism of CMC and its defining formula. Next, the impacts of various factors on CMC in stroke patients were discussed individually. Lastly, this paper addresses current challenges and future prospects for CMC.

脑卒中患者皮质肌肉一致性的影响因素

脑卒中又称脑血管意外，是一种发病率、致残率、死亡率均较高的急性脑血管疾病。它可以破坏大脑皮层和外部肌肉之间的相互作用。皮质肌肉一致性 (CMC) 是研究大脑皮层如何控制肌肉活动的常用且有用的方法。 CMC可以暴露皮层和肌肉之间的功能连接，反映运动系统中的信息流。与 CMC 相关的传入反馈可以揭示这些功能连接。本文旨在探讨影响脑卒中患者CMC的因素，并对目前该领域的研究进行全面的总结和分析。本文首先讨论中风的影响以及 CMC 对中风患者的意义。然后详细阐述了CMC的机制及其定义公式。接下来分别讨论各种因素对脑卒中患者CMC的影响。最后，本文讨论了 CMC 当前的挑战和未来的前景。
