Spontaneous movement tempo can be influenced by combining action observation and somatosensory stimulation.

摘要: Spontaneous movement tempo (SMT) was a popular field of study the Gestalt psychologists It can be determined from subjects freely tapping out rhythm with their finger, and it has been found to average about 2 Hz. A previous showed that SMT changed after observation rhythmical movements performed at frequency different SMT. This effect long-lasting only when execution immediately followed action (AO). We recently demonstrated AO combined peripheral nerve stimulation (AO-PNS) possible induce plastic changes in excitability motor cortex, whereas PNS alone did not evoke any changes. Here we investigated whether actions higher than induced lasting even absence immediate execution. Forty-eight participants were assigned four groups. In AO-PNS group they observed video showing right hand performing finger opposition sequence 3 Hz contemporarily received an electrical median nerve; either same or group, respectively; LANDSCAPE neutral video. Participants spontaneous rate before 30 min conditioning protocols. Results significantly AO-PNS. result suggested protocol able due neuroplasticity mechanisms, indicating application rehabilitative treatments.
