Modeling Metacarpophalangeal Joint Movement Using Functional Electrical Stimulation Based on Muscle Synergy

Abstract

The application of functional electrical stimulation in human motor control such as motor skill teaching and motor capability expansion is recently expected. In case of human finger control, however, the higher kinematic and actuation redundancies of the finger joint make such an application more difficult. In order to solve this problem, we proposed the coordinated electrical stimulation of the agonist-antagonist muscles based on muscle synergy known as one of the human motor control strategy, and identified the finger joint equilibrium point control model.
