| Research Abstract |
This report describes the development of a physical support system which enhances motor skills in human voluntary movement. The main features of the proposed system are as follows :(1) The novel concepts of Agonist-antagonist muscle-pairs ratio(A-A ratio) and Agonist-antagonist muscle-pairs activity(A-A activity) are introduced for extracting muscle synergies from EMG signals of multiple flexor and extensor muscles.(2) The extracted muscle synergies are used for an evaluation of motor skills and an improvement of motor performance. We experimentally show that the modification of muscle-activity balance between agonist-antagonist muscles leads to the improvement of motor performance. Our approach would be useful for establishing a novel teaching method in sports coaching and rehabilitation.
