Popis: Fifteen healthy participants (6 males and 9 females) have participated. There was a total of six groups as three groups per condition; 80:80 Hz, 115:45 Hz, and 70:0 Hz as a co-vibration frequency pattern which was attached to the flexor carpi radialis (FCR) and extensor carpi radialis (ECR) muscle of the right hand following without-cover-hand and with-cover-hand conditions. Electroencephalogram (EEG) was used to measure the alpha (α), beta (β), and gamma (γ) frequency bands of ERD on the C3, CP3, and P3 of the left cortical area according to 10-10 EEG electrode system, electromyography (EMG) was used to measure FCR and ECR muscle activities, also kinesthetic perception was assessed by measuring the sense of the position of our body and sense of movement by 7 Linkert scale. We look forward to this symposium, which will impart this study’s knowledge as a part of the rehabilitation context to the physiotherapist with clinical and research experience. It might be possible to assume two components from this study's result. First, neuronal oscillation activity of the α-band and γ-band might reflect the kinesthetic illusion induced by co-vibration but not the β-band. Second, frequency differences between vibration sides were more critical during vibration than the absolute total frequency to induce neuronal oscillation and muscular activity following a kinesthetic illusion. This study aimed to investigate 1) the event-related desynchronization (ERD) of neuronal oscillation, 2) muscular activity, during co-vibration with and without a vision of one's hand, 3) which neuronal oscillation band of the neural activity showed a relationship with the motor activity of the peripheral muscle following a kinesthetic illusion. ECR-EMG significantly differed between 70:0 Hz without-cover-hand and with-cover-hand conditions (p0.37), and also between γ-band of P3 and 7Linkert feeling of illusory-movement (p0.40).
