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.
