“Intermuscular coherence”的意思、由来-开放百科全书

The synchronisation of motor units of a single muscle in animals and humans are known for decades. The early studies that investigated the relationship of EMG activity used time-domain cross-correlation to quantify common input.^[3]^[4] The explicit notion of presence of synchrony between motor units of two different muscles was reported at a later time.^[5] In the 1990s, coherence analysis was introduced to examine in frequency content of common input.^[2]

Physiology

Intermuscular coherence can be used to investigate the neural circuitry involved in motor control. Correlated muscle activity indicates common input to the motor unit pools of both muscles^[6]^[7] and reflects shared neural pathways (including cortical, subcortical and spinal) that contribute to muscle activity and movement.^[8] The strength of intermuscular coherence is dependent on the relationship between muscles and is generally stronger between muscle pairs that are anatomically and functionally closely related.^[9]^[10] Intermuscular coherence can therefore be used to identify impairments in motor pathways.^[11]^[12]
