Research Reveals Concussion Effects Persist in Rugby Players Despite Clearance to Play

Recent research from the University of Essex highlights a critical concern in grassroots rugby: players may still experience brain alterations after being cleared to return to play, raising questions about the effectiveness of current concussion management protocols. The study tracked an amateur rugby team across a demanding 22-game season, utilizing advanced brain imaging technology to monitor changes in brain activity. Despite feeling symptom-free and receiving clearance based on existing guidelines, seven out of eight players with concussion histories displayed abnormal brain responses days after injury.

Led by Dr. Ben Jones—an ex-international rugby player—the research employed functional near-infrared spectroscopy (fNIRS) to measure brain activity. The study involved 67 participants, including 41 rugby players and 26 non-players. Baseline tests performed at the season's start, middle, and end revealed that nearly all concussed players showed elevated brain activity levels that persisted beyond the typical recovery timeline outlined in Rugby Football Union protocols.

This finding suggests that the current return-to-play standards may not sufficiently account for ongoing brain recovery, emphasizing the potential need for personalized concussion assessments. Dr. Jones advocates integrating brain imaging into concussion management to improve safety and reduce long-term risks. The collaboration with PhysiGo, a wearable tech company, aimed to develop cost-effective, community-based solutions for monitoring concussive forces and aiding recovery.

As part of the study, players underwent monitoring while performing cognitive tasks to track brain recovery over time. Extending this initiative, Colchester Rugby Club plans to expand the study to include their women's team, underscoring a commitment to player health.

Dr. Jones underscores that the goal is not to discourage rugby but to enhance player safety through innovative, individualized approaches. Experts like Dr. Jay Perrett from PhysiGo support the integration of accessible brain monitoring tools to ensure long-term well-being for all levels of play.

This pioneering research indicates that relying solely on symptom resolution may overlook ongoing brain recovery, calling for a revision of concussion protocols to safeguard athletes beyond immediate symptoms. More comprehensive, scientifically supported methods could lead to safer participation and reduce the risk of chronic brain issues in the future.
