An estimated 136 000 concussions occur per academic year in high schools alone. The effects of repetitive concussions and the potential for catastrophic injury have made concussion an injury of significant concern for young athletes.
The objective of this study was to describe the mechanism of injury, symptoms, and management of sport-related concussions using the High School Reporting Information Online (HS RIO) surveillance system.
Descriptive epidemiology study.
All concussions recorded by HS RIO during the 2008-2009 academic year were included. Analyses were performed using SPSS software. Chi-square analysis was performed for all categorical variables. Statistical significance was considered for P < .05.
A total of 544 concussions were recorded. The most common mechanism (76.2%) was contact with another player, usually a head-to-head collision (52.7%). Headache was experienced in 93.4%; 4.6% lost consciousness. Most (83.4%) had resolution of their symptoms within 1 week. Symptoms lasted longer than 1 month in 1.5%. Computerized neuropsychological testing was used in 25.7% of concussions. When neuropsychological testing was used, athletes were less likely to return to play within 1 week than those for whom it was not used (13.6% vs 32.9%; P < .01). Athletes who had neuropsychological testing appeared less likely to return to play on the same day (0.8% vs 4.2%; P = .056). A greater proportion of injured, nonfootball athletes had computerized neuropsychological testing than injured football players (23% vs 32%; P = .02)
When computerized neuropsychological testing is used, high school athletes are less likely to be returned to play within 1 week of their injury. Concussed football players are less likely to have computerized neuropsychological testing than those participating in other sports. Loss of consciousness is relatively uncommon among high school athletes who sustain a sport-related concussion. The most common mechanism is contact with another player. Some athletes (1.5%) report symptoms lasting longer than 1 month.
仅在高中阶段，每年就有约 136000 例脑震荡发生。由于重复性脑震荡的影响以及潜在的灾难性伤害，脑震荡已成为年轻运动员严重关注的受伤问题。
本研究旨在使用高中报告信息在线（HS RIO）监测系统描述运动相关脑震荡的损伤机制、症状和管理。
描述性流行病学研究。
纳入 HS RIO 在 2008-2009 学年记录的所有脑震荡。使用 SPSS 软件进行分析。对所有分类变量进行卡方分析。P <.05 认为具有统计学意义。
共记录了 544 例脑震荡。最常见的机制（76.2%）是与另一名运动员接触，通常是头部与头部的碰撞（52.7%）。93.4%有头痛；4.6%失去意识。大多数（83.4%）症状在 1 周内得到缓解。1.5%的症状持续时间超过 1 个月。25.7%的脑震荡使用了计算机神经心理学测试。当使用神经心理学测试时，运动员在 1 周内重返赛场的可能性低于未使用神经心理学测试的运动员（13.6%比 32.9%；P <.01）。使用神经心理学测试的运动员重返赛场的可能性较低（0.8%比 4.2%；P =.056）。受伤的非足球运动员比受伤的足球运动员更有可能接受计算机神经心理学测试（23%比 32%；P =.02）。
当使用计算机神经心理学测试时，高中运动员在受伤后 1 周内重返赛场的可能性较低。与其他运动项目相比，足球运动员脑震荡接受计算机神经心理学测试的可能性较低。在发生运动相关脑震荡的高中运动员中，失去意识相对少见。最常见的机制是与另一名运动员接触。一些运动员（1.5%）报告症状持续时间超过 1 个月。
