 Stroke causes motor impairments due to damage to the neural networks that control movement. Corticomuscular coherence, CMC, is a valid way to measure the functional connectivity between the brain and muscle fibers. Studies have shown that CMC is reduced in stroke patients compared to healthy individuals. This reduction in CMC is associated with decreased mobility and functioning. Furthermore, CMC can be used as a rehabilitation assessment biomarker in stroke patients. This article was authored by Rui Su, Hai Chao Zhang, Shan Lixue, and others.
