El için Robotik Ayna Terapi Sisteminin Geliştirilmesi

Bu bildiride, geliştirmekte olduğumuz ince kavrama hareketi odaklı robotik rehabilitasyon sistemi genel hatlarıyla sunulmuştur. Geliştirilen sistemde ayna terapi esas alınmıştır. Hazırlanan videoları seyreden hastaya, ilgili ince kavrama hareketlerinin robot marifetyle uygulanması hedeflenmiştir. Hareketin gözlenmesi, imgelemi ve yerine getirilmesi sürecini bütünüyle kapsayan sistemde, EEG ölçümü de yer almaktadır. Ayna nöron aktivitesini ve kortikospinal uyarılabilirliği arttırmayı hedefleyen yaklaşım ile hazırlanan videoların izlenmesi sırasında yepılan EEG kayıtları, mu ve beta baskılanmasının incelenmesine de imkan tanımaktadır. Geliştirilen sistemin ilerleyen dönemlerde kişiye özel görüntülerin izlenmesi, imgelemi ve tatbiki ile optimal terapi amaçlı kullanılması hedeflenmektedir.In this paper, the robotic hand therapy system that we have been developing is discussed. It is based on the mirror therapy. It is aimed to assist the patient as he observes the pinching motion in the movie. The system that covers the action observation, motor imagery and execution includes EEG analysis, as well. The movies are prepared so as to increase the corticospinal excitability and the mirror neuron system activity. The EEG data is utilized to analyze the mu and beta suppression. In the future, the developed system is planned to be used for the purpose of optimal therapy by observing and imagining the motions in the personally prepared movies

Analysis of mirror neuron system activation during action observation alone and action observation with motor imagery tasks

This study aimed to explore the relationship between action observation (AO)-related corticomotor excitability changes and phases of observed action and to explore the effects of pure AO and concurrent AO and motor imagery (MI) state on corticomotor excitability using TMS. It was also investigated whether the mirror neuron system activity is muscle-specific. Fourteen healthy volunteers were enrolled in the study. EMG recordings were taken from the right first dorsal interosseous and the abductor digiti minimi muscles. There was a significant main effect of TMS timing (after the beginning of the movement, at the beginning of motor output state, and during black screen) on the mean motor evoked potential (MEP) amplitude. Mean MEP amplitudes for AO combined with MI were significantly higher than pure AO session. There was a significant interaction between session and TMS timing. There was no significant main effect of muscle on MEP amplitude. The results indicate that corticomotor excitability is modulated by different phases of the observed motor movement and this modulation is not muscle-specific. Simultaneous MI and AO enhance corticomotor excitability significantly compared to pure AO
