目的：运动医学中的一个常见假设是，脑震荡史预示着后续脑震荡损伤的阈值较低，以及后续脑震荡损伤后的结局更差。本研究旨在探讨高中运动员脑震荡史与随后脑震荡后症状的现场表现之间的关系。方法：173名经历过运动相关脑震荡的运动员组成初始研究组。随后，根据脑震荡史创建了二元组。将60名无脑震荡史的运动员与28名有三次或三次以上脑震荡史的运动员进行了比较：在研究中脑震荡后的现场症状表现方面进行了比较。因变量包括伤后意识丧失，。结果：有三次或三次以上脑震荡的运动员在随后的脑震荡后更可能经历场上积极的意识丧失（chi（2）= 8.0，P = 0.005）、顺行性遗忘（chi（2）= 5.5，P = 0.019）和意识混乱（chi（2）= 5.1，P = 0.024）。比值比显示，有三次脑震荡病史的运动员，脑震荡的几率是其他运动员的9.3倍。可能比没有脑震荡史的运动员表现出三到四个异常的脑震荡严重程度的现场标志物：结论：这项研究是第一个提出脑震荡在高中运动员中的累积效应。在有明显脑震荡史的高中运动员中，脑震荡标志物的现场表现更为严重。这项研究的发现强调了需要对高中运动员进行更多的长期结果研究，这些运动员持续与运动有关的脑震荡。
OBJECTIVE: A common assumption in sports medicine is that a history of concussion is predictive of a lower threshold for, as well as a worse outcome after, subsequent concussive injury. The current study was conducted to investigate the relationship between concussion history in high school athletes and the on-field presentation of symptoms after subsequent concussion.METHODS: One hundred seventy-three athletes who experienced sports-related concussion composed the initial study group. Binary groups were subsequently created on the basis of concussion history. Sixty athletes with no concussion history were compared with 28 athletes with a history of three or more concussions: The groups were compared in terms of the on-field presentation of symptoms after an in-study concussion. Dependent variables included the postinjury presence of loss of consciousness,. anterograde amnesia, retrograde amnesia, and confusion.RESULTS: Athletes with three or more prior concussions were more likely to experience on-field positive loss of consciousness (chi(2) = 8.0, P = 0.005), anterograde amnesia (chi(2) = 5.5, P = 0.019), and confusion (chi(2) = 5.1, P = 0.024) after a subsequent cerebral concussion. An odds ratio revealed that, athletes with a history of three, concussions were 9.3 times more. likely than athletes with no history of concussion to demonstrate three to four abnormal on-field markers of concussion severity:CONCLUSION: This study is the first to suggest a cumulative effect of concussion in high school athletes. A more severe on-field presentation of concussion markers is evidenced in high school athletes with a pronounced history of concussion. This study's findings highlight the need for more long-term outcome studies in high school athletes who sustain sports-related concussions.
