Summary

Concussions in rugby can stem from single severe impacts or repeated lower-force head impacts. Monitoring both peak and cumulative head acceleration metrics is crucial for understanding concussion risk in athletes.

Area of Science:

  • Sports Medicine
  • Biomechanics
  • Neurology

Background:

  • Investigates biomechanical data from instrumented mouthguards (iMGs) in professional Under 21 rugby union players.
  • Focuses on three confirmed concussion cases within a larger dataset of head acceleration events.

Purpose of the Study:

  • To present biomechanical profiles of concussions in young elite rugby players.
  • To explore the role of single high-magnitude and cumulative head impacts in concussion.
  • To highlight the utility of iMGs in capturing concussion-related kinematic data.

Main Methods:

  • Collected head acceleration data using iMGs across 34 matches (254 player matches).
  • Analyzed 4414 head acceleration events (HAEs), correlating them with three diagnosed concussions.
  • Measured peak linear acceleration (PLA), peak angular acceleration (PAA), peak angular velocity (PAV), change in peak angular velocity (ΔPAV), and Rotational Velocity Change Index (RVCI).

Main Results:

  • Concussions were associated with varying levels of peak and cumulative kinematic metrics.
  • One player experiencing loss of consciousness had the highest ΔPAV and RVCI.
  • Another player with cumulative angular load, despite no single clear impact, suggests sub-concussive exposure is relevant.

Conclusions:

  • Concussions in rugby can result from single severe impacts or cumulative head trauma.
  • Multi-metric monitoring, including angular measures and cumulative load, is essential for concussion assessment.
  • This study pioneers the use of iMGs for reporting both peak and cumulative kinematic data in rugby concussion research.
