Dundee University scientists have called for mandatory protective rugby headgear after a study showed it can cut impact levels by almost half.
The research showed that even the least effective device tested could make a “significant difference” in preventing head injuries, such as concussion.
The team said the study made a “compelling case” for protective headgear at all levels of the game.
The findings have been published in The BMJ.
All headguards reduced the linear acceleration experienced on impact.
The Canterbury Ventilator was the most effective, while the XBlades Elite was the least effective.
The headguards used may not prevent all concussive injuries, but there is the potential for them to reduce the incidence.
