The Military Acute Concussion Evaluation 2 (MACE 2), which includes the Vestibular-Ocular Motor Screening (VOMS) tool and the single-leg stance component of the modified Balance Error Scoring System (mBESS), was introduced in 2018 as an assessment of acute mTBI in US military personnel. However, the reliability of the VOMS and mBESS in this population has not been established.
The primary purpose of this study was to examine the reliability of the VOMS across a 6-month period in healthy, uninjured US Army Special Operations Command (USASOC) personnel.
Active duty/heathy military personnel (n=108) completed the VOMS and mBESS at baseline and follow-up 6 months later (±1 month).
Cronbach's alpha was used to examine the internal consistency of the VOMS and mBESS at both time points. Two-way mixed intra-class correlation coefficients (ICC) with consistency agreement were used to evaluate test-retest reliability.
VOMS demonstrated excellent internal consistency (α=0.99), whereas, the mBESS demonstrated poor internal consistency (α=0.29). Test-retest reliability of VOMS items was moderate-to-good with ICCs ranging from 0.60 to 0.81. Test-retest reliability was moderate for mBESS total score (ICC=0.59) and double-leg stance (ICC=0.73), while single-leg (ICC=0.49) and tandem (ICC=0.02) stances were poor.
The findings suggest that VOMS has high internal consistency and moderate-to-good test-retest reliability. mBESS has poor internal consistency and poor-to-moderate test-retest reliability. The results suggest that VOMS is a reliable addition to the MACE-2, whereas, mBESS single-leg stance is less reliable. As such, mBESS double-leg stance may be a more reliable measure of balance in this population.
军事急性脑震荡评估 2 版（MACE 2）于 2018 年推出，其中包括前庭眼动筛查（VOMS）工具和改良平衡错误评分系统（mBESS）的单腿站立部分，用于评估美国军事人员的急性 mTBI。然而，在该人群中，VOMS 和 mBESS 的可靠性尚未确定。
本研究的主要目的是在 6 个月的时间内，检测健康、未受伤的美国陆军特种作战司令部（USASOC）人员的 VOMS 可靠性。
现役/健康军人（n=108）在基线和 6 个月后的随访（±1 个月）时完成了 VOMS 和 mBESS。
在两个时间点使用 Cronbach's alpha 检验 VOMS 和 mBESS 的内部一致性。使用具有一致性协议的双向混合组内相关系数（ICC）评估测试-重测可靠性。
VOMS 显示出极好的内部一致性（α=0.99），而 mBESS 显示出较差的内部一致性（α=0.29）。VOMS 项目的测试-重测可靠性为中等到良好，ICC 范围为 0.60 至 0.81。mBESS 总分（ICC=0.59）和双腿站立（ICC=0.73）的测试-重测可靠性为中等，而单腿（ICC=0.49）和串联（ICC=0.02）站立的可靠性较差。
研究结果表明，VOMS 具有高内部一致性和中等到良好的测试-重测可靠性。mBESS 具有较差的内部一致性和较差到中等的测试-重测可靠性。结果表明，VOMS 是 MACE-2 的可靠补充，而 mBESS 的单腿站立则不太可靠。因此，在该人群中，mBESS 的双腿站立可能是更可靠的平衡测量方法。
