简要总结
This is an exploratory observational study.
Broadcasted video footage is used to review all head impacts during all 64 matches in the football tournament.
All head impacts are registered, and simple descriptive statistics are used to create overviews of the head impact characteristics, including video signs of potential concussion, observed contact, location of the head impact, presence and timing of medical assessment, whether there was foul play and sanction, and if the player was substituted.
详细描述
This study will be performed at the FIFA World Cup 2022, a football tournament including 32 national men's senior football teams. The tournament includes 64 matches played in Qatar between November 20th and December 18th, 2022.
Recording of head impacts The investigators will use injury spotters and subsequent video footage review to study head impacts. All matches will be attended by one of eight FIFA injury spotters, who will register all head impacts on a standardized scoring form. All FIFA injury spotters are qualified medical doctors with experience in football medicine and are also FIFA Medical Coordinators in other matches at the same tournament. The injury spotters are positioned on the tribune above the midline of the pitch with visibility of the entire pitch. If the injury spotter observes a head impact, they can review video footage on a large computer screen immediately to identify possible mechanism of injury and the presence of video signs indicating a possible concussion. The injury spotter can select one or more angles for review at the same time (up to four close views and four wide views) and rewind and forward at different speeds, including frame-to-frame views.
A modification of a previous definition of a head impact was clarified to: "a direct head impact, or impact with indirect forces to the head, where a player is unable to immediately resume play following impact or subsequently shows potential concussion-related symptoms."
Video signs The investigators adjusted the video signs used in previous FIFA tournaments, which included the six internationally standardized video signs of potential sport-related concussions (in bold). Further signs were added and grouped into yellow and red flag categories.
If a yellow flag is observed, the injury spotter informs the FIFA Medical coordinator with details (including player team and number, mechanism of injury, and any video signs of possible concussion), and they will contact the team doctor with the recommendations for video review of the head impact and a clinical assessment. Further action will depend on the clinical assessment findings.
