To establish the King-Devick test (KD) performance values for children and adolescents.
Prospective cohort.
Pediatric sports medicine clinics.
Five hundred seven athletes presenting to a pediatric sports medicine clinic for non-concussion-related evaluations.
Age, sex, and risk factors for abnormal concussion recovery.
The King-Devick test time.
Four hundred eighty-three participants were included in the final analysis, which included 60.5% girls (n = 292) and 39.5% boys (n = 191). The KD test performance varied by age with a steady decrease in test time yearly from 8 years through 14 years of age, where some plateauing occurred. Baseline scores changed approximately 31 seconds over ages 8 to 18. Analysis of variance results revealed a strong effect of age on overall mean KD time (P < 0.001). The KD test performance was not associated with sex or other studied concussion risk factors or comorbid conditions.
The KD test performance was reported in a cohort of youth aged 8 to 18 years, allowing for comparison of performance in individuals who may not have a baseline assessment. If baseline testing is desired, at least yearly intervals seems to be appropriate through childhood and early adolescence.
建立儿童和青少年 King-Devick 测试（KD）的表现值。
前瞻性队列研究。
儿科运动医学诊所。
507 名运动员因非脑震荡相关评估而就诊于儿科运动医学诊所。
年龄、性别和异常脑震荡恢复的危险因素。
King-Devick 测试时间。
483 名参与者被纳入最终分析，其中包括 60.5%的女孩（n=292）和 39.5%的男孩（n=191）。KD 测试表现因年龄而异，从 8 岁到 14 岁，每年的测试时间逐渐减少，之后出现一些平台期。基线分数在 8 至 18 岁之间变化约 31 秒。方差分析结果表明，年龄对总体平均 KD 时间有很强的影响（P<0.001）。KD 测试表现与性别或其他研究的脑震荡危险因素或合并症无关。
KD 测试表现报告了一个 8 至 18 岁的青少年队列，允许对可能没有基线评估的个体的表现进行比较。如果需要基线测试，至少每年一次似乎是儿童和青春期早期的合适间隔。
