Comparison of the on-line effects of different motor simulation conditions on corticospinal excitability in healthy participants

Abstract In healthy participants, corticospinal excitability is known to increase during motor simulations such as motor imagery (MI), action observation (AO) and mirror therapy (MT), suggesting their interest to promote plasticity in neurorehabilitation. Further comparing these methods and investig...
