Bradford J. McFadyen, PhD, is a professor within the Department of Rehabilitation at Université Laval, as well as a researcher at the Centre for Interdisciplinary Research in Rehabilitation and Social Integration (CIRRIS). He is also a Research Fellow of the Canadian Institute for Military and Veteran Health Research. Dr. McFadyen’s research program spans from basic to applied work related to walking and mobility in healthy and pathological populations (particularly ABI). Basic work strives to understand how walking is controlled within different environments across adulthood as well as following injury and trauma. This research involves the use of virtual reality to control environmental characteristics and social situations. On the applied side, he uses evidence to design clinical protocols using both real and virtual environments to better assess function and expose residual deficits to help clinicians make better decisions about return to function.
