Study Details

Study Description

Brief Summary

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.

Condition or Disease	Intervention/Treatment	Phase
Concussion, Mild	Device: Headpulse measurements

Detailed Description

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.
