Abstract

Objective

To develop clinical cutoffs using change scores for the VOMS individual items and an overall VOMS change score that identified concussion in adolescent athletes.

Methods

Change score clinical cutoffs were calculated from a sample of adolescents (13–18 years) with SRC (n=147) and a sample of uninjured adolescents CONTROL (n=147). Receiver operating characteristic (ROC) curves, with area under the curve (AUC), based on Youden’s J statistic were used to identify optimal cutoffs for identifying SRC from CONTROLS using VOMS individual item change scores, an overall VOMS change scores, and NPC distance (cm).

Results

AUC values for VOMS item change scores ranged from .55 to .71. Optimal change score cutoffs were ≥1 for VOMS items and ≥3 for overall VOMS change score. The optimal cutoff for NPC distance was ≥3 cm. A ROC analysis revealed a three-factor model (AUC = .76) for identifying SRC that included vertical vesibular ocular reflex (VVOR), visual motion sensitivity (VMS), and NPC distance items. The AUC (.73) for the overall VOMS change score was higher than any individual VOMS AUC values.

Conclusions

This study supports an alternate scoring approach and clinical interpretation of VOMS items involving change scores that account for pretest symptoms.

使用前庭眼球运动筛查 (VOMS) 工具的变化分数来识别青少年脑震荡

摘要

客观的

使用 VOMS 单个项目的变化评分和识别青少年运动员脑震荡的总体 VOMS 变化评分来制定临床临界值。

方法

变化评分临床截止值是根据 SRC 青少年(13-18 岁)样本(n = 147)和未受伤青少年 CONTROL(n = 147)样本计算的。接受者操作特征 (ROC) 曲线,具有曲线下面积 (AUC),基于 Youden 的J统计量,用于使用 VOMS 单个项目变化评分、总体 VOMS 变化评分和 NPC 距离来确定从 CONTROLS 中识别 SRC 的最佳截止值。厘米)。

结果

VOMS 项目变化分数的 AUC 值范围为 0.55 至 0.71。VOMS 项目的最佳变化评分截止值≥1,整体 VOMS 变化评分≥3。NPC 距离的最佳截止值是≥3 cm。ROC 分析揭示了用于识别 SRC 的三因素模型 (AUC = .76),其中包括垂直前庭眼反射 (VVOR)、视觉运动敏感性 (VMS) 和 NPC 距离项目。总 VOMS 变化评分的 AUC (.73) 高于任何单个 VOMS AUC 值。

结论

这项研究支持一种替代评分方法和 VOMS 项目的临床解释,这些项目涉及解释前测症状的变化分数。
