The University of Tennessee Chattanooga – Association of Perception-Action Coupling with Concussion History and Self-Rated Function

Background:

• Up to 1.2 million injuries per year occur in high school and college football, most of which are sprains and strains1

• Athletes who have sustained a concussion appear to be at greater risk for sustaining a musculoskeletal injury2

• Risk factors for football-related injury may include deficits in reaction time (RT), memory, and peripheral vision

• RT encompasses amount of time required for: 1) perception, 2) decision, and 3) motor response3

• Cognitive control refers to brain processes associated with perception, memory, and action4

• Perception-Action coupling specifically refers to rapid responsiveness to environmental stimuli

• Anticipatory and/or rapid muscle activation that initiates movement and optimizes stiffness of body segments

• The purpose of this study was to assess the potential value of a reactive agility test for identification of persisting effects of concussion on perception-action coupling and self-rated function of college football players
