Human Head Impact Dose Concussion Risk Functions and Sensor-Based Military Specific Environmental Monitoring System
Abstract
For the annual reporting period, the project has completed all the specific aims in the statement of work. Aim 1 for laboratory calibration has been finished for laboratory comparison to Hybrid III ATD, with the impact monitoring mouth guard system fitting a linear model versus Reference, of the form IMM=0.97*REF+1.2, with a correlation coefficient (R2=0.97). Aim 2 was designed to correlate a dose-response relationship between head impact and clinical behavioral assessments for American football players in Wisconsin Division III football. SCAT3 symptom scores rose from pre-season to midseason assessments, yet by seasons end the symptoms had resolved. The SAC cognitive tests were not correlated to head impact exposure. Aim 3--to quantify head impacts across a variety of military and athletic populations at the US Air Force Academy, US Military Academy, at MCW and in parachutists at the POMPOC National Guard event--was successfully completed, and ongoing data collection in the coming year will serve to increase the depth and breadth of this work. Over 2,000 head impacts were independently confirmed with video recordings of activity; the parachute work was the first time in recorded history that a parachutists' head impact was accurately measured and confirmed with time-synchronized video. In Aim 4 the project correlated measured head impacts with a 'check engine' behavior seen on video. This Aim was completed and resulted in the publication of the article in the Annals of Biomedical Engineering entitled "High Energy Side and Rear American Football Head Impacts Cause Obvious Performance Decrement on Video." In the final year of the study we will continue this work and use the 'check engine' thresholds to ensure any subjects who sustain these types of impacts will be made known to appropriate clinical staff regardless of whether they self-report.
