Corticomuscular coherence in acute and chronic stroke

Question: After stroke a profound neuronal reorganization occurs and new, previously not engaged areas can be recruited in motor activities. However, not all post-stroke neuronal changes contribute directly to motor recovery by re-establishing fine motor control. Corticomuscular coherence (CMC) is a measure which allows tracing neuronal reorganizations that are functionally relevant for motor recovery. Previous CMC studies were performed only in chronic stroke stage when many compensatory processes already took place. In order to study the development of compensatory changes, we aimed at studying CMC in patients…
