To conduct the first video analysis of concussion in the Australian National Rugby League (NRL) and describe player and injury characteristics, situational factors and time to return to play.
Descriptive, observational case series.
Video analysis of 20 medically diagnosed concussions for three consenting clubs during the 2013 NRL season.
Most concussions (83%) occurred during a high tackle, and all injured ball carriers were hit high. Loss of consciousness was observed in 30% of cases. Common observable signs of injury included clutching of the head, balance problems or wobbly legs and a blank or vacant state. There were no post-concussive seizures. All players with loss of consciousness were removed from play. However, only half of the total sample was removed from play and one athlete who was removed returned to play in the same match. Of the players who were removed from play, the large majority returned the following week. Illegal play accounted for 25% of all concussions.
Video analysis may be a useful method to study the incidence, mechanism and management of concussion in sports such as Rugby League. Future studies may include larger numbers to validate this preliminary data and may also investigate other levels of play and age ranges.
对澳大利亚国家橄榄球联盟（NRL）的脑震荡进行首次视频分析，并描述球员和损伤特征、情境因素以及恢复比赛的时间。
描述性观察性病例系列研究。
对2013年NRL赛季中三个同意参与研究的俱乐部里20例经医学诊断的脑震荡进行视频分析。
大多数脑震荡（83%）发生在高位阻截时，所有受伤的持球球员均被高位撞击。30%的病例观察到意识丧失。常见的明显损伤迹象包括捂住头部、平衡问题或腿部摇晃以及茫然或失神状态。没有出现脑震荡后癫痫发作。所有意识丧失的球员都被换下比赛。然而，总样本中只有一半被换下，且有一名被换下的运动员在同一场比赛中又重返赛场。在被换下比赛的球员中，绝大多数在下周回归。违规动作导致的脑震荡占所有脑震荡的25%。
视频分析可能是研究橄榄球联盟等体育运动中脑震荡的发生率、机制和处理方式的一种有用方法。未来的研究可能会纳入更多样本以验证这些初步数据，也可能会调查其他比赛级别和年龄范围。
