Improving Concussion Education: Do Athletic Trainers’ Opinions Match Expert Consensus? Open
Context The National Collegiate Athletic Association and Department of Defense (NCAA-DoD) Mind Matters Challenge created “useful and feasible” consensus recommendations to improve concussion care-seeking behavior in collegiate athletes and…
View article: Trunk and Lower Extremity Biomechanics in Female Athletes With and Without a Concussion History
Trunk and Lower Extremity Biomechanics in Female Athletes With and Without a Concussion History Open
Context Athletes with a history of concussion are at a greater risk for lower extremity musculoskeletal injury. Female athletes may be at an even greater risk than male athletes. Previous researchers on postconcussion landing biomechanics …
