¹Bloorview Research Institute, Holland Bloorview Kids Rehabilitation Hospital, ²Department of Occupational Science and Occupational Therapy, University of Toronto, ³Graduate Department of Rehabilitation Science, University of Toronto

This article provides an overview of a multi-modal approach to assessing recovery following concussion in youth athletes. The described protocol uses pre- and post-concussion assessment of performance across a wide variety of domains and can inform the development of improved concussion rehabilitation protocols specific to the youth sport community.
