Consideration of the Training Possibility of Upper Extremity in the VR-based Throwing Environment by Physically Challenged Persons

The effectivity of training used the virtual training environment for upper extremity by throwing motion is considered from changes of the motion performance of physical challenged persons. Experimental participants with disabilities on upper extremity enabled a smoother motion after about thirty practices than at the beginning of training. And, in spite of one participant couldn´t perform smoothly motion even an experimenter instructed the way of motion of upper extremity, he generated the smooth motions by an instruction based on ball´s motion showed on the display. From these results it is confirmed temporary improvement of throwing skill by repeated practices using the virtual training environment.
