Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The incidence of Sports-related concussions (SRCs) has risen in recent years, not least in ice hockey, and available treatment options are limited. Here, we addressed the hypotheses that immediate controlled head- and neck cooling could hasten return-to-play in a Swedish cohort of concussed professional ice hockey players. Over three seasons, 15 teams used either immediate head- and neck cooling or standard management for SRC. All players (81) followed the same return-to-play management protocol.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sports-related concussions (SRCs) are a growing health concern, since they may lead to persistent symptoms and, particularly if repeated, to e.g. depression, accelerated dementia onset, and development of chronic traumatic encephalopathy. Here, we addressed the hypotheses that immediate controlled head- and neck cooling could hasten return-to-play in a Swedish cohort of concussed professional ice hockey players. Over three seasons, 15 teams used either immediate head- and neck cooling or standard management for SRC. All players followed the same return-to-play management protocol. Using a baseline questionnaire, no difference in the number of previous SRCs between groups was observed. In total, 92 SRCs were recorded. Eleven players did not complete the study protocol, and thus 81 players were included. Of these, 29 were treated by immediate selective head- and neck cooling for ≥ 30 min, and 52 controls received standard acute SRC management.

Allocation Method

RANDOMIZED

Intervention Model

SINGLE_GROUP

Twenty-eight teams from the elite ice hockey leagues for males in Sweden were invited to participate in the study. Participating teams were given the option to be in the study group (receiving selective head-neck cooling after SRC) or the control group (standard SRC management). Any player with a suspected or diagnosed concussion was immediately removed from practice or game participation for further evaluation. Concussion diagnosis was established using the concussion in the sports consensus statement. At the time of SRC, any presence of "red flags" mandated the player to be taken to the hospital. As soon as the diagnosis of SRC was established the player was included in the study and players in the intervention teams were treated by selective head-neck cooling system for a minimum of 30 minutes. The primary endpoint of the study was the time (in days) from concussion until returning to full practice or game.
