ABSTRACT

Background

Most post-concussion eye movement (EM) research involves predominantly male samples. We evaluated pro- (PRO; reflexive shift of visual attention to target) and anti- (ANTI; executive control of visual attention away from target) computer-based saccade task performance among female, collegiate athletes with recent concussion (CON) versus healthy-control athletes (HC). We evaluated the relationship between EM performance and post-concussion outcomes. We hypothesized ANTI performance would differ among CON and HC due to greater executive control demands, and that EM performance (both tasks) would be associated with clinical outcomes in CON.

Methods

16 CON (assessed 4–10 days post-injury [M = 6.87, SD = 2.15 days]) and 16 age-matched HC athletes were recruited. General linear mixed modeling and Pearson’s correlations were used.

Results

On ANTI, CON demonstrated higher error rate [F(1,2863) = 12.650, p<.001] and shorter latency on error trials [F(1,469) = 5.976, p=.015] relative to HC. Multiple EM measures were associated with clinical outcomes: PRO duration predicted days to symptom remission (r=.44, p <.05); ANTI error rate was associated with symptom burden on the day of testing (r=.27, p <.05).

Conclusion

This study demonstrates promising utility of EM measures to detect cognitive control and sensorimotor effects of concussion among female athletes and their use as a prognostic indicators of recovery.

女运动员脑震荡后的眼动表现和临床结果

摘要

背景

大多数脑震荡后眼动 (EM) 研究主要涉及男性样本。我们评估了最近患有脑震荡 ( CON ) 的女性大学生运动员与健康 -控制运动员（HC）。我们评估了 EM 表现与脑震荡后结果之间的关系。我们假设CON和HC 的ANTI 表现会因更大的执行控制需求而不同，并且 EM 表现（两项任务）将与CON 的临床结果相关。

方法

招募了16 名CON（在受伤后 4-10 天评估 [M = 6.87，SD = 2.15 天]）和 16 名年龄匹配的HC运动员。使用了一般线性混合模型和 Pearson 相关性。

结果

在 ANTI 上，CON表现出更高的错误率 [ F (1,2863) = 12.650, p <.001] 和更短的错误试验延迟 [ F (1,469) = 5.976, p =.015] 相对于HC。多项 EM 测量与临床结果相关：PRO 持续时间预测症状缓解的天数 ( r =.44, p <.05)；ANTI 错误率与测试当天的症状负担相关（r = .27，p <.05）。

结论

这项研究证明了 EM 措施在检测女运动员脑震荡的认知控制和感觉运动影响方面的有希望的效用，并将其用作恢复的预后指标。
