Modulation of corticomuscular coherences by proprioceptive somatomotor leg training

Background: Corticomuscular coherence (CMC) is a measure of the degree of coupling of electrical oscillations arising in the cerebral cortex and muscles, but its functional significance is poorly understood. Little is known about the modulation of CMC by practice. As leg training has been shown to induce cortical plasticity, it might influence functional changes mediated by CMC. It remains unknown, whether alterations of functional connectivity to the lower limb display regional specificity or rather affect the wider network of muscle control. Objective: To assess effects of a somatomotor proprioceptive training…
