Abstract

Background: Vision encompasses a large component of the brain's pathways, yet is not represented in current sideline testing.

Objectives: We performed a meta-analysis of published data for a vision-based test of rapid number naming (King-Devick [K-D] test).

Studies & methods: Pooled and meta-analysis of 15 studies estimated preseason baseline K-D scores and sensitivity/specificity for identifying concussed versus nonconcussed control athletes.

Result: Baseline K-D (n = 1419) showed a weighted estimate of 43.8 s (95% CI: 40.2, 47.5; I² = 0.0%; p=0.85 - indicating very little heterogeneity). Sensitivity was 86% (96/112 concussed athletes had K-D worsening; 95% CI: 78%, 92%); specificity was 90% (181/202 controls had no worsening; 95% CI: 85%, 93%).

Conclusion: Rapid number naming adds to sideline assessment and contributes a critical dimension of vision to sports-related concussion testing.

King-Devick快速数字命名测试用于脑震荡检测:文献荟萃分析和系统回顾。

背景:视觉包含了大脑通路的一个很大的组成部分，但在目前的业余测试中并没有体现出来。目的:我们对已发表的基于视觉的快速数字命名测试(King-Devick [K-D]测试)数据进行了荟萃分析。研究与方法:对15项研究进行汇总和荟萃分析，估计季前基线K-D评分以及识别脑震荡与非脑震荡对照运动员的敏感性/特异性。结果:基线K-D (n = 1419)加权估计为43.8 s (95% CI: 40.2, 47.5;I2 = 0.0%;P =0.85 -表明异质性很小)。敏感性为86%(96/112脑震荡运动员有K-D恶化;95% ci: 78%， 92%);特异性为90%(181/202对照无恶化;95% ci: 85%， 93%)。结论:快速数字命名增加了边线评估，并为运动相关脑震荡检测提供了一个关键的视觉维度。
