Day of Game Injury Identification and Assessment

i. Match Play Video Review and Analysis

This research program has reviewed match play video of head impact events, head injury assessments, and medically diagnosed concussions in professional rugby league and rugby union. This ongoing research program aims to review and refine the video signs of concussion as an adjunct tool for the medical professional to assist in the management of game day incidents.

ii. Impact Sensor Validation

This research program is examining the use of impact sensors to quantify the extent and quantity of impacts that occur during match play, and validate the tool as a possible adjunct tool for the identification of possible concussion in match play. This research program will conduct:

  1. Video verification research examining direct head impacts
  2. Peak accelerations associated with medically diagnosed concussions
  3. Associations between peak acceleration thresholds and cumulative exposure and visible signs of concussion on video
  4. Comparison of acceleration thresholds associated with direct head impacts and indirect head impacts

iii. Sports Concussion Assessment Tool (SCAT) Research

The SCAT is a tool that has been universally adopted as a clinical support tool for day of game and subsequent assessment, of an athlete suspected of having sustained a concussion. Our research program has evaluated the performance of fatigued athletes on the SCAT, and evaluated video signs, day of game SCAT performance and subsequent medical diagnosis of concussion. We are continuing to be involved in collaborative work on the SCAT and conduct our own research looking at day of game performance, baseline performance, and serial use of the SCAT.

iv. Cognitive Assessment Validation Research

The clinical validation program is focused on creating a normative database, while also examining construct validity (convergent and divergent validity), and test retest reliability (sensitivity, specificity, positive predictive value, and negative predictive value) of a number of unique tools in an attempt to advance the sensitivity of detecting subtle cognitive deficits in concussed athletes, and to track their cognitive recovery over time.
