While factors like sex influence the effects of concussion, cognitive and motor challenges performed during gait evoke further deficits. The purpose of this thesis is to characterize factors that may affect gait velocity in people with concussion. Chapter 1 addresses the current literature on gait and concussion as they relate to sex, identifies gaps in the literature, and consolidates this information as a conceptual model. Chapters 2 and 3 focus on the studies that were conducted in this thesis. The findings of Chapter 2 highlight the different strategies that men and women use to achieve gait velocity, as well as sex-dependent differences in Step Length Variability. In Chapter 3, a lack of consistency is reported in the factors that predict concussion-induced alterations in gait over time. Finally, Chapter 4 discusses the overall findings of this thesis and presents an updated conceptual model.Author owns copyright, except where explicitly noted.
