Combining Motor Imagery and Action Observation with Vibratory Stimulation Increases Corticomotor Excitability in Healthy Young Adults

Vibratory stimulation but also motor imagery and action observation can induce corticomotor modulation, as a bottom-up stimulus top-down stimuli, respectively. However, it remains unknown whether the combination of imagery, observation, vibratory effectively increase excitability. This study aimed to investigate effect and/or in presence or absence stimulation, on excitability healthy young adults. was provided palm right hand. Action consisted viewing movie someone else’s finger flexion extension movements. The condition required participants imagine they were moving their fingers while attempting move accordance with movie. Eleven right-handed adults asked perform six conditions randomly: 1) 2) 3) blank screen, 4) 5) 6) screen. Single-pulse transcranial magnetic conducted assess peak-to-peak amplitude evoked potentials. results showed that increases corticospinal findings further revealed performing movement is more effective at inducing an augmentation compared alone. Thus, augment
