The newest iteration has greater functionality, in a smaller form-factor, enabling more complex conditions (e.g., assisting balance across multiple axes) and facilitating use among patient populations. She discussed the results from the previous version as well as future experiments and other uses for this novel actuator.

Dr. Karl Newell, Department of Kinesiology, University of Georgia

​

Dr. Newell's presentation focused on the learning of new patterns of coordination in human movement.  This a property of skill acquisition that has been underplayed in the traditions of motor learning due to the selection of so-called ‘simple’ low degrees of freedom (DF) tasks or those tasks where the individual can already produce the qualitative properties of the coordination pattern.  The role of order parameters/collective variables from a dynamic systems framework is considered as essential to the early formative stage of skill acquisition.  Theoretical, experimental and practical implications and challenges of this approach to the learning of movement forms will be discussed.
