Time Course And Temporal Order Of Changes In Movement Kinematics During Learning Of Fast And Accurate Elbow Flexions, D. Flament, M. Shapiro, T. Kempf, D. Corcos

Timothy Kempf

Learning of a motor task, such as making accurate goal-directed movements, is associated with a number of changes in limb kinematics and in the EMG activity that produces the movement. Some of these changes include increases in movement velocity, improvements in end-point accuracy, and the development of a biphasic/triphasic EMG pattern for fast movements. One question that has remained unanswered is whether the time course of the learning-related changes in movement parameters is similar for all parameters. The present paper focuses on this question and presents evidence that different parameters evolve with a specific temporal order. Neurologically normal subjects were …
