2A1-I01 Elucidation of Joint Coordination with UCM Analysis during Dart Throwing Motion in Healthy People(Mobiligence and Embodiment)

Abstract

In order to improve physical function of elderly people, they need to get physical training. There are activities which require integrated lower body and arm. However there are no quantitative testing methods of the degree of recovery for the coordination between arm movements and lower body movements. In this study, we focus on dart throwing motion to suggest the quantitative evaluation of the coordination between arm movements and lower body movements in dart throwing motion. Joint coordination was analyzed with uncontrolled manifold (UCM) analysis at different throwing distances. It is suggested that the joint coordination in order to achieve the same elbow position is mostly required in dart throwing motion.
