Abstract
In this report, we studied the perception of body information and actual action of hemiplegia patients in relation to regulation and learning in motor impairment. There are two functions in perception in terms of control: self perception and environment perception. In order to measure these two functions in hemiplegia patients, we set up a passage through an opening, a limited perception condition. In the π value, the timing difference in the perception of body information and actual action is important. It was confirmed that the passage of each patient through the opening was different; i.e. there was no fixed pattern of movement, indicating that there is diversity in the motor learning and regulation of perception in adapting to the environment. We discuss the implications for therapeutic exercise.
