Research Abstract	The purpose of this study was investigated to a real time modification strategy for quick elbow movements by using the agonist and antagonist muscle activity as an indicator of the control process in the central nervous system. Experimental tasks were to modify the movement amplitude in response to a modification signal presented before or after the movement commencement. As the main results, there were three modification strategies depend on the stage of motion execution. By having an experience with modification of the movement amplitude, the agonist muscle activity was inhibited previously and the movement amplitude was modified by controlling this activity after presenting a modification signal.
