Abstract

Examining quantitative parameters of the blink reflex may improve sport-related concussion (SRC) diagnosis and management because it may serve as an objective measure of injury severity and recovery. However, the psychometric properties of several FDA-cleared devices assessing the blink reflex are understudied. The current study compared blink reflex parameters pre- and post-season using the BlinkTBI EyeStatTM device to assess its reliability in non-concussed athletes. A cohort of high school athletes underwent pre- and post-season BlinkTBI EyeStatTM testing. Statistical analysis included Spearman correlations, Wilcoxon signed-rank tests, and interclass correlations for ten blink parameters. Multivariable linear regressions assessed the influence of contact (i.e., soccer, football) vs. non-contact sports (i.e., baseball, softball, basketball) on changes in blink parameters. Among 32 athletes with pre- and post-season testing (age: mean = 15.3, SD = 1.1; 53.1% female), 19 played non-contact and 21 played contact sports. Most parameters were not statistically different between pre- and post-season, except for delta 30 (W = 229.5, p = 0.015), time under threshold (W = 191.0, p = 0.003), and oscillations (W = 667.0, p < 0.001). Parameters exhibited moderate to excellent reliability (interclass correlations = 0.575–0.872, p-values = 0.001–0.004). Spearman’s rho values ranged from 0.435 to 0.828 (p-values = 001–0.005). Participation in contact vs. non-contact sports was not associated with changes in blink parameters (all p-values>0.05). Preliminary evidence suggest stable blink parameters across a sports season in non-concussed athletes when measured by the BlinkTBI EyeStatTM device. Contact sport participation was not significantly associated with changes in blink parameters. The findings add to the psychometric evidence that the blink reflex can be reliably measured, warranting further study on its utility in concussion.

A - 55 非晕厥运动员眨眼反射参数的赛季前与赛季后可靠性

检查眨眼反射的定量参数可以改善运动相关脑震荡（SRC）的诊断和管理，因为它可以作为衡量损伤严重程度和恢复情况的客观指标。然而，美国食品和药物管理局（FDA）批准的几种评估眨眼反射的设备的心理测量特性尚未得到充分研究。本研究使用 BlinkTBI EyeStatTM 设备比较了赛季前和赛季后的眨眼反射参数，以评估其在非昏迷运动员中的可靠性。一组高中运动员接受了赛季前和赛季后的 BlinkTBI EyeStatTM 测试。统计分析包括十个眨眼参数的斯皮尔曼相关性、Wilcoxon符号秩检验和类间相关性。多变量线性回归评估了接触性运动（即足球、橄榄球）与非接触性运动（即棒球、垒球、篮球）对眨眼参数变化的影响。在 32 名接受季前和季后测试的运动员中（年龄：平均 = 15.3，标准差 = 1.1；53.1% 为女性），19 人从事非接触式运动，21 人从事接触式运动。除了δ30（W = 229.5，P = 0.015）、阈值下时间（W = 191.0，P = 0.003）和振荡（W = 667.0，P 0.05）外，大多数参数在赛季前和赛季后没有统计学差异。初步证据表明，使用 BlinkTBI EyeStatTM 设备测量非脑震荡运动员的眨眼参数时，其在整个运动赛季中的眨眼参数是稳定的。参与接触性运动与眨眼参数的变化无明显关联。这些研究结果为眨眼反射的可靠测量提供了更多心理测量学证据，值得进一步研究其在脑震荡中的应用。

期刊介绍： The journal publishes original contributions dealing with psychological aspects of the etiology, diagnosis, and treatment of disorders arising out of dysfunction of the central nervous system. Archives of Clinical Neuropsychology will also consider manuscripts involving the established principles of the profession of neuropsychology: (a) delivery and evaluation of services, (b) ethical and legal issues, and (c) approaches to education and training. Preference will be given to empirical reports and key reviews. Brief research reports, case studies, and commentaries on published articles (not exceeding two printed pages) will also be considered. At the discretion of the editor, rebuttals to commentaries may be invited. Occasional papers of a theoretical nature will be considered.
