The Emergence of Movement Dynamics in Selective Infant Leg Action

  • The purpose of this study is to investigate the biomechanical factors that contribute to the early emergence of selective leg action. We define selective leg action as the coordination between intralimb leg joints that allows increased degrees of freedom among joints. We compare dynamics between a 2D and 3D computation of torques and the dynamics that emerge longitudinally as infants mature in the first months of life.
