Australian University of California San Francisco (UCSF) Concussion in Athletes (AUSSIE-2)

University of California, San Francisco68 enrolled

Overview

Analysis of cardiac induced brain forces using cranial accelerometry has been shown to diagnose concussion in high school athletes. This trial expands on this observation by recording headpulse signals in a recently concussed athletes playing Australian rules football.

Recently concussed athletes will have headpulse measurements obtained as soon after the clinically identified concussion as is feasible and at 1-3 day intervals over the course of a month. These recordings will pair with a self administered neurological symptom inventory (NSI) to track the athletes subjective concussion symptoms. Data from the prior study (AUSSIE-1) will be used to confirm the predictive value of the established algorithm
