Concussions incurred during high school athletics are a significant health concern, and studies examining concussions with a symptom resolution time (SRT) of 15 to 28 days have been limited.
To compare concussions that had an SRT of 15 to 28 days with concussions that had an SRT of greater than 28 days among US high school athletes.

MAIN OUTCOME MEASURE(S): Concussion frequency, symptom number, and symptom prevalence.
Among all 917 reported concussions (of which 50.8% had missing SRT), 88 had an SRT recorded as 15 to 28 days, and 29 had an SRT recorded as greater than 28 days. Greater frequencies of concussions with an SRT of 15 days or more were reported in boys' sports (n = 78) than girls' sports (n = 39). Boys' football (51.7%) and girls' basketball (11.5%) accounted for the largest proportions of all reported concussions with an SRT of 15 to 28 days; boys' football (58.6%) accounted for the greatest proportion of concussions reported with an SRT greater than 28 days. The average number of symptoms was 6.3 ± 3.4 for concussions with an SRT of 15 to 28 days and 7.2 ± 3.8 for those with an SRT greater than 28 days. The most frequently reported symptoms in concussions with both SRT of 15 to 28 days and greater than 28 days were headache, dizziness, sensitivity to light, and difficulty concentrating. The prevalence of irritability was higher in concussions with an SRT of 15 to 28 days as compared with concussions with an SRT greater than 28 days (26.1% versus 13.8%); visual problems (48.3% versus 35.2%) and hyperexcitability (24.1% versus 15.9%) were more prevalent in concussions with an SRT greater than 28 days, although differences were not statistically significant.
Symptom prevalence and total count were comparable between concussions with an SRT of 15 to 28 days and those with an SRT of greater than 28 days with no statistically significant difference, suggesting that symptom burdens within these groups are more similar than they are different.
高中体育活动中发生的脑震荡是一个严重的健康问题，目前已有研究对脑震荡的症状持续时间（SRT）为 15 至 28 天的病例进行了研究，但这些研究十分有限。

脑震荡频率、症状数量和症状发生率。
在所有 917 例报告的脑震荡中（其中 50.8%的 SRT 缺失），88 例的 SRT 记录为 15 至 28 天，29 例的 SRT 记录大于 28 天。SRT 为 15 天或以上的脑震荡在男生运动项目（78 例）中的报告频率高于女生运动项目（39 例）。男生足球（51.7%）和女生篮球（11.5%）占所有报告的 SRT 为 15 至 28 天的脑震荡的最大比例；SRT 大于 28 天的脑震荡中，男生足球（58.6%）占比最大。SRT 为 15 至 28 天的脑震荡平均症状数为 6.3±3.4，SRT 大于 28 天的脑震荡平均症状数为 7.2±3.8。SRT 为 15 至 28 天和大于 28 天的脑震荡最常报告的症状均为头痛、头晕、对光敏感和注意力难以集中。SRT 为 15 至 28 天的脑震荡中易激惹的发生率高于 SRT 大于 28 天的脑震荡（26.1%比 13.8%）；SRT 大于 28 天的脑震荡中视觉问题（48.3%比 35.2%）和过度兴奋（24.1%比 15.9%）更为常见，但差异无统计学意义。
SRT 为 15 至 28 天和大于 28 天的脑震荡的症状发生率和总数相当，无统计学差异，这表明这些组内的症状负担更相似，而不是不同。
