Background. Rugby league is a physically demanding team sport and the National Rugby League is the highest-level competition of rugby league in Australia. Frequent tackles and collisions between players result in a high incidence of injury to players. Concussion injuries have been the source of much debate, with reporting varying greatly depending on the definition used. Method. Injury records of 239 players from one professional National Rugby League were analysed during a continuous period of 15 years, with particular interest in the incidence and recurrence of concussions and the change in incidence over time. Result. A total of 191 concussions were recorded, affecting 90 players. The incidence of concussion injuries was found to be 28.33 per 1000 player match hours, with an increase over time (P = 0.0217). Multiple concussions were recorded for 51 players. Conclusion. A statistically significant increase in the incidence of concussion injuries was found, without a concurrent increase in the number of head injuries or total injuries. New rules which mandate removal of players from the field may be beneficial for protection of players on the long term, although they risk being counterproductive, if they make players less likely to report their symptoms during matches.
背景。橄榄球联盟是一项对体能要求很高的团队运动，而国家橄榄球联盟是澳大利亚橄榄球联盟的最高级别赛事。球员之间频繁的擒抱和碰撞导致球员受伤的发生率很高。脑震荡损伤一直是诸多争论的根源，其报告情况因所使用的定义不同而有很大差异。方法。对来自一个职业国家橄榄球联盟的239名球员连续15年的伤病记录进行了分析，特别关注脑震荡的发生率、复发情况以及发生率随时间的变化。结果。共记录到191次脑震荡，涉及90名球员。脑震荡损伤的发生率为每1000球员比赛小时28.33次，且随时间有所增加（P = 0.0217）。51名球员有多次脑震荡记录。结论。发现脑震荡损伤的发生率有统计学意义的增加，而头部受伤或总受伤次数并未同时增加。强制球员下场的新规则从长远来看可能有利于保护球员，不过如果这些规则使球员在比赛中不太可能报告自己的症状，那么可能会适得其反。
