TORONTO - A study of young hockey players, coaches and parents suggests there's a dangerous lack of knowledge about whether it's safe to play with a concussion, how it's treated and what symptoms constitute the brain injury.
The study by Dr. Michael Cusimano, a neurosurgeon at Toronto's St. Michael's Hospital, was based on interviews with 142 coaches, trainers and parents, and 267 players.
Cusimano found about one in four minor-league players didn't know whether it was OK to return to the ice with a concussion.
About half the players and one in four adults either could not identify any concussion symptoms or knew only one.
The study, published in the May edition of the Canadian Journal of Neurological Sciences, suggests young players aged five through 17 have about 2.8 concussions per 1,000 hours of ice time.
University and elite-level amateur players have rates of 4.2 and 6.6 concussions per 1,000 hours.
