“…The EMG activity was viewed on 2 computer monitors. The EMG signal was displayed on a scale of 500 μV/division (10 divisions = full scale) on one monitor and on a scale of almost 100 μV/division (maximum scale) on the other monitor [14,23]. A trial was rejected if a small level of muscle activation was observed during the testing.…”

“…In clinical situations, however, interventions other than transcranial stimulation are needed to facilitate cortical potentiation because of epilepsy, limited resources, or patient preference. In such cases, we attempt to provide some form of sensory input (e.g., visual input) [14] or ES, which have been used to improve muscular strength for purposes of rehabilitation.…”

BackgroundThe combination of voluntary effort and functional electrical stimulation (ES) appears to have a greater potential to induce plasticity in the motor cortex than either electrical stimulation or voluntary training alone. However, it is not clear whether the motor commands from the central nervous system, the afferent input from peripheral organs, or both, are indispensable to induce the facilitative effects on cortical excitability. To clarify whether voluntary motor commands enhance corticospinal tract (CoST) excitability during neuromuscular ES, without producing voluntary muscular contraction (VMC), we examined the effect of a combination of motor imagery (MI) and electrical muscular stimulation on CoST excitability using transcranial magnetic stimulation (TMS).MethodsEight neurologically healthy male subjects participated in this study. Five conditions (resting, MI, ES, ES + MI [ESMI], and VMC) were established. In the ES condition, a 50-Hz stimulus was applied for 3 to 5 s to the first dorsal interosseous (FDI) while subjects were relaxed. In the MI condition, subjects were instructed to imagine abducting their index finger. In the ESMI condition, ES was applied approximately 1 s after the subject had begun to imagine index finger abduction. In the VMC condition, subjects modulated the force of index finger abduction to match a target level, which was set at the level produced during the ES condition. TMS was applied on the hotspot for FDI, and the amplitude and latency of motor evoked potentials (MEPs) were measured under each condition.ResultsMEP amplitudes during VMC and ESMI were significantly larger than those during other conditions; there was no significant difference in MEP amplitude between these 2 conditions. The latency of MEPs evoked during MI and VMC were significantly shorter than were those evoked during rest and ES.ConclusionsMEP acutely reinforced in ESMI may indicate that voluntary motor drive markedly contributes to enhance CoST excitability, without actual muscular contraction.

“…The prefrontal cortex is considered to participate in the neural processing of kinesthetic illusions [4,26]. Specifically, the right prefrontal area is considered to participate in neural processing that helps to distinguish one's self from others [26].…”

“…A previous study showed that motor-evoked potentials were elicited when individuals observed images of finger movements [3]. Moreover, another study reported that individuals who passively observed abducted and adducted finger movements that were aligned with their actual hand position and projected onto a screen reported the perception of selfagency [4]. However, hand function is not merely finger movement; it also involves object manipulations [2,[5][6][7].…”

Self-agency is the recognition of one's own movement and plays a vital role in purposeful, voluntary movement. A sense of self-agency can be elicited in individuals who view their own simple finger movements as they are projected onto a screen and aligned with their actual hand position. Here, we examined whether individuals perceived self-agency when they viewed a video of a hand grasping a wooden cylinder and whether the perception of self-agency correlated with simultaneous changes in oxy-hemoglobin in the parietal or the prefrontal cortical areas. All participants reported the perception of self-agency, which was correlated with oxy-hemoglobin increases in the right prefrontal area. We conclude that self-agency also relates to hand-held objects displayed on video.

“…A vibrating stimulation on a tendon has been reported to elicit vivid illusory limb movement, and increase both corticomotor excitability and the activation of motor‐related areas (Naito et al ., , , ; Naito, ). A visual stimulation in which someone else's finger movement is presented on a computer screen above the subject's real hand has been shown to induce a kinesthetic illusion and increase the excitability of M1 (Kaneko et al ., ; Aoyama et al ., ; Nojima et al ., ). Moreover, it has been reported that visual information overrides proprioceptive information if a discrepancy exists between the two (Brass et al ., ; Edwards et al ., ).…”

After watching sports, people often feel as if their sports skills might have been improved, even without any actual training. On some occasions, this motor skill learning through observation actually occurs. This phenomenon may be due to the fact that both action and action observation (AO) can activate shared cortical areas. However, the neural basis of performance gain through AO has not yet been fully clarified. In the present study, we used transcranial magnetic stimulation to investigate whether primary motor cortex (M1) plasticity is a physiological substrate of AO-induced performance gain and whether AO itself is sufficient to change motor performance. The excitability of M1, especially that of its intracortical excitatory circuit, was enhanced after and during AO with kinesthetic illusion but not in interventions without this illusion. Moreover, behavioral improvement occurred only after AO with kinesthetic illusion, and a significant correlation existed between the performance gain and the degree of illusion. Our findings indicated that kinesthetic illusion is an essential component of the motor learning and M1 plasticity induced by AO, and this insight may be useful for the strategic rehabilitation of stroke patients.
