The King-Devick (K-D) test is a rapid visual screening tool that can assess underlying brain trauma such as concussion via impairments in saccadic rhythm. A new tablet version of the K-D test using randomized numbers is now available, but reliability for this new version and comparison to the traditional K-D test has not yet been reported. Known for learning effects in the test, the aim of this study was to determine test–retest reliability and to compare performance of the new “randomized” version to the “traditional” K-D test version. We hypothesized that the “traditional” K-D test would show a greater rate of improvement with repeat application, compared with the “randomized” K-D test.

新随机King-Devick检验的可靠性和比较分析。

King-Devick（KD）测试是一种快速的视觉筛查工具，可以评估潜在的脑部创伤，例如因拍打节奏的损害而导致的脑震荡。现在可以使用使用随机数的KD测试的新平板电脑版本，但是尚未报告该新版本的可靠性以及与传统KD测试的比较。以测试中的学习效果而闻名，这项研究的目的是确定测试-再测试的可靠性，并将新的“随机”版本与“传统” KD测试版本的性能进行比较。我们假设与“随机” KD测试相比，“传统” KD测试在重复应用时显示出更大的改善率。
