Intermuscular coherence
Intermuscular Coherence is the synchrony between the neural activity of two muscles, which can be typically assessed from the electromyographic (EMG) recordigs of the muscles.
Physiology
The synchronisation of motor units of a single muscle in animals and humans appears to be known for decades. The presence of synchrony between (the motor units of) two different muscles was reported at a later time[1]. This synchrony between two muscles can be quantified and described in frequency domain[2], which is referred to as Intermuscular Coherence[3].
