The purpose of this study is to investigate the functional posture of the index finger with the surface EMG (electromyography) in order to define the rest state of the index finger. The variation of EMG responses of muscles driving the index finger actions was statically or dynamically measured at some postures of the index finger. The three finger postures were defined in the experiment. Whether the functional posture of the index finger can be determined with the variation of surface EMG of muscles of the index finger was investigated. It was suggested that it is possible to distinguish the functional posture of the index finger with the surface EMG of two or more muscles statically.
