Title of Abstract

Introduction: While most symptoms from concussions recover in 7-10 days [1], challenging motor control tasks can be affected longer. Concussed athletes have shown prolonged changes in challenging motor control tasks such as dual-task gait [2], but only traditional stability measures such as medio-lateral (ML) sway have been investigated thus far. The current investigation compared the local dynamic stability (LDS) of recently concussed athletes to matched controls to identify lasting motor control abnormalities, even after the concussed athletes returned to competition.
