Assessment Of Multiple Concussive Athletes With Dual Task Triple Stroop And Aerobic Exercise, Sierra Duran, Sarah A. Massey, Ariel Gomez, Matthew A. Barlow 5622543

International Journal of Exercise Science: Conference Proceedings

BACKGROUND: Athletic concussion testing has mostly recently relied on a sedentary computer neurocognitive test battery called the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Previous tests directly compare baseline with post-concussion analysis of patient in regards to different cognitive aspects including; working memory, processing speed, and response time. No physical tests are included in the ImPACT analysis for return-to-play action. PURPOSE: In previous studies from our lab in these populations we concluded that the combination of a physical neural impediment with cognitive tests (dual-task with balance impairment) created a greater degree of impairment not observed in the sedentary ImPACT test. …
