The predominant mechanism of concussion was consistently characterised by player-to-opponent contact… contact was often to the lateral aspect of the head…
Despite all efforts there is no conclusive evidence that rule changes or other measures lead to a decrease in the actual incidence of concussions over the last few decades.
HUC is an objective, reliable tool for coding the antecedent events and mechanisms of concussions in the NHL.
For men and women, contact with another player was the most frequent impact mechanism, and contact with the ice generated the greatest-magnitude head accelerations.
We conclude that rules regulating bodychecking to the head did not reduce the number of players suffering concussions during NHL regular season play
Male youth athletes reporting headache and neck pain at baseline were at an increased risk of concussion during the season. The risk associated with dizziness and any 2 of dizziness, neck pain, or headaches depended on age group and body checking.
