Study on Motion Recognition by Movement-Related Cortical Potential for Elbow and Shoulder Joints Coordinated Movements in Upper-Limb Power Assistance Based on EEG

Abstract

In our laboratory, we aim at the realization of the Upper-Limb power assistance system based on Electroencephalogram(EEG). In this study, we focused on potential fluctuation occurred before and after voluntary movement called Movement-Related Cortical Potential (MRCP) and investigated features of elbow, shoulder and coordinated movement. As a result, P+160 which is one of the MRCP components at C3 of elbow movement is bigger than shoulder movement, and compared to single movement, the potential of coordinated movement fluctuated characteristically in all the subjects. The results suggest that it is possible to recognize each movement by using these features.
