Outline of Final Research Achievements

We have experienced that the subject’s hand autonomously begin to move during the subject is feeling kinesthetic illusion induced by visual stimulation (KiNvis). This autonomic movement is unconscious one and the subject does not perceive the movement (non-perceived movement: NPM). We hypothesized that this biomechanical behavior, observed in the subject during KiNvis, may be a result of sensory-motor integration. Specifically, the neurological mechanisms following the visual stimulus may begin to work parallel with KiNvis and provoke the mechanical effect in the body segment. The present study clarified whether training to strengthen KiNvis induce NPM and corticospinal excitability change. The result of this study indicated that the visual stimulus of a moving-hand image induced spontaneous muscle activity synchronized with the visually presented movements, and increased the corticospinal excitability after KiNvis training.
