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 will be used to confirm prior models of analysis and produce a tool to be confirmed in a future study.
