Investigating vibration-induced neural plasticity in healthy subjects

Focal vibration (FV), applied to a relaxed muscle or tendon, generates repeated micro-stretches that enhance Ia afferent discharge and activate both spinal and cortical networks. Neuroimaging and electrophysiological studies have shown that FV induces acute increases in corticospinal excitability and cortical priming, while prolonged application reduces spinal reflex excitability, an effect of interest for spasticity management. When repeated over several weeks, FV can promote long-term plasticity and strength gains in both vibrated and contralateral muscles, mainly through neural adaptations.
