    Concussion Management: Examining Movement Behaviours in Adolescents Following Concussion
    (2024-08-27) Kennedy, Courtney; Smirl, Jonathan; Emery, Carolyn; Schneider, Kathryn; Brassard, Patrice; Russell, Kelly
    Concussion management guidelines have evolved over time and current recommendations indicate a gradual reintroduction to sub-symptom threshold activity following a brief (24-48 hour) period of relative rest. Both excessive rest and activity following concussion have been shown to be associated with adverse outcomes, suggesting a dose-response relationship between activity and recovery. However, the optimal frequency, timing, and duration of activity to augment recovery has yet to be delineated following concussion. Movement behaviours, including physical activity, sedentary behaviour, and sleep, are finite in nature and effectuate both independent and collective effects contributing to health outcomes. Concussion related impairments can manifest as functional disturbances encompassing numerous sleep/wake domains; however, activity and sleep patterns are often examined independently among adolescents following concussion. There is a limited understanding of the differential effect of activity across the intensity spectrum, as the accumulation of physical activity and sedentary behaviour across the wakeful day has yet to be explored in adolescents’ post-injury. This MSc project contains two projects focused on quantifying movement behaviour patterns including the volume of sedentary time, light-, moderate-, vigorous-intensity physical activity, and sleep. The first project evaluates movement behaviour metrics in healthy adolescents and adolescents diagnosed with a concussion. The second project examines the differential effect of movement behaviour volume on recovery trajectories. The comprehensive evaluation of physical activity, sedentary behaviour, and sleep patterns can aid in delineating the optimal balance between rest and activity, and ultimately inform evidence-based movement guidelines in the management and rehabilitation of concussion.
