Dynamic Modulation of Corticospinal Excitability and Short-Latency Afferent Inhibition during Onset and Maintenance Phase of Selective Finger Movement

摘要

ObjectiveDuring highly selective finger movement, corticospinal excitability is reduced in surrounding muscles at the onset of movement but this phenomenon has not been demonstrated during maintenance of movement. Sensorimotor integration may play an important role in selective movement. We sought to investigate how corticospinal excitability and short-latency afferent inhibition changes in active and surrounding muscles during onset and maintenance of selective finger movement.
