We used injury spotters and video footage review to establish the frequency of head impacts, their characteristics, and the subsequent medical assessment during the FIFA Arab Cup 2021. Six defined video signs of potential concussion based on an international consensus were used. A total of 88 head impacts were observed, with a median of 2 (IQR 1.5-4, range 0-7) head impacts per match, of which 44 (50%) resulted in on-pitch medical assessment. The median assessment duration was 51s (IQR 34-65s, range 19-262s). The most common mechanism was head-to-head contact (27% of all impacts and 43% of impacts with medical assessment). Seven head impacts showed video signs of potential concussion: six had one sign and one had two signs. The concussion substitution was used in three incidents. Head impacts during the FIFA Arab Cup were common and a median of 1 head impact per game required an on-pitch medical assessment. Only 8% of the head impacts showed any video sign of potential concussion, and only 3% resulted in a concussion substitution. The medical on-pitch assessments appeared too short (<1 min) to allow an appropriate assessment of all head impacts, indicating a need for further evaluation. Further standardisation of the injury spotter's role in football is recommended.
我们使用伤检员和视频回放审查来确定 2021 年国际足联阿拉伯杯期间头部撞击的频率、特征以及随后的医疗评估。使用了基于国际共识的 6 种潜在脑震荡的明确视频征象。共观察到 88 次头部撞击，每场比赛中位数为 2（IQR1.5-4，范围 0-7）次，其中 44 次（50%）导致了场上的医疗评估。中位数评估持续时间为 51 秒（IQR34-65 秒，范围 19-262 秒）。最常见的机制是头对头接触（所有撞击的 27%和有医疗评估的撞击的 43%）。有 7 次头部撞击显示出潜在脑震荡的视频征象：其中 6 次有 1 个征象，1 次有 2 个征象。有 3 次使用了脑震荡替换。国际足联阿拉伯杯期间的头部撞击很常见，每场比赛中位数有 1 次头部撞击需要进行场上医疗评估。只有 8%的头部撞击显示出任何潜在脑震荡的视频征象，只有 3%导致脑震荡替换。场上的医疗评估似乎太短（<1 分钟），无法对所有头部撞击进行适当评估，表明需要进一步评估。建议进一步规范伤检员在足球中的作用。
