Time Course And Temporal Order Of Changes In Movement Kinematics During Motor Learning: Effect Of Joint And Instruction, T. Kempf, D. Corcos, D. Flament

Timothy Kempf

Learning a motor task is associated with specific changes in movement kinematics. Recently, it has been shown that changes in different kinematic parameters occurred with different time courses for subjects who practiced simple, single-joint elbow movements. For example, movement time was seen to decrease and level off in a shorter time than peak velocity, which increased and plateaued later. What is not known, however, is whether the time course and temporal order of these learning-related changes seen at the elbow are similar for movements learned at other joints and with different instructions. In this study, neurologically normal subjects practiced 50°-flexion …
