Test–retest reliability of the Vestibular Ocular Motor Screening (VOMS) tool and modified Balance Error Scoring System (mBESS) in US military personnel

The Military Acute Concussion Evaluation 2 (MACE 2), which includes the Vestibular-Ocular Motor Screening (VOMS) tool and single-leg stance component of modified Balance Error Scoring System (mBESS), was introduced in 2018 as an assessment acute mTBI US military personnel. However, reliability VOMS mBESS this population has not been established. Objectives primary purpose study to examine across a 6-month period healthy, uninjured Army Special Operations Command (USASOC) Design Active duty/heathy personnel (n = 108) completed at baseline follow-up 6 months later (±1 month). Method Cronbach's alpha used internal consistency both time points. Two-way mixed intra-class correlation coefficients (ICC) with agreement were evaluate test–retest reliability. Results demonstrated excellent (α 0.99), whereas, poor 0.29). Test–retest items moderate-to-good ICCs ranging from 0.60 0.81. moderate for total score (ICC 0.59) double-leg 0.73), while 0.49) tandem 0.02) stances poor. Conclusions findings suggest that high poor-to-moderate results is reliable addition MACE-2, less reliable. As such, may be more measure balance population.
