This test assesses gaze stability during active head movements by measuring the loss of visual acuity relative to static visual acuity. Participants read an eye chart (ETDRS in this study) while performing horizontal head rotations at a standardized frequency. The change in the number of lines read compared to static visual acuity is recorded, with a loss of three or more lines considered clinically significant. Smaller losses indicate better vestibulo-ocular function.

A clinician-administered screening tool that evaluates symptom provocation associated with vestibular and ocular motor function. Baseline symptoms (headache, dizziness, nausea, fogginess) are rated on a 0-10 scale. After each task (smooth pursuits, saccades, near point of convergence, vestibulo-ocular reflex, and visual motion sensitivity), participants re-rate symptoms on the same scale. Total and change scores are calculated, with higher scores indicating greater symptom provocation.

A performance-based mobility assessment that combines multiple challenging gait and balance tasks, including fast walking, backward walking, pivot turn, and walking with head turns. Performance is scored across four components, with a maximum total score of 14. When wearable sensors are used, spatiotemporal gait, and/or postural sway measures may also be derived.Higher scores indicate better overall mobility and balance performance.

A computerized neurocognitive assessment battery used to evaluate cognitive domains commonly affected following mild traumatic brain injury, including attention, processing speed, working memory, and reaction time. The assessment is administered on a computer or tablet, and performance metrics are automatically recorded. Higher scores and faster reaction times generally indicate better cognitive performance, depending on the specific subtest.

A laboratory-based balance assessment using pseudorandom stimuli including surface and/or visual tilt to quantify sensory weighting, motor activation parameters (stiffness and damping), and feedback time delay during standing balance.

A 2-item self-report questionnaire used to assess the severity of depressive symptoms over the past two weeks. Each item is scored on a 3-point Likert scale from 0 (not at all) to 3 (nearly every day), yielding a total score range of 0 to 6. Higher scores indicate greater severity of depressive symptoms.

A 6-item self-report questionnaire designed to assess an individual's ability to recover or "bounce back" from stress. Items are rated on a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). Scores are averaged across items, with higher scores indicating greater resilience.

A 10-item self-report questionnaire that assesses neck-related disability during daily activities. Each item is scored from 0 (no disability) to 5 (complete disability), resulting in a total score ranging from 0 to 50. Higher scores indicate greater neck-related disability.

Performance is quantified using distance walked during the one-minute period. When wearable sensors are used, spatiotemporal gait, and/or postural sway measures may also be derived. Greater distance indicates better walking performance.

Assesses walking performance under divided attention. Participants are instructed to walk continuously for one minute at a self-selected comfortable pace while simultaneously performing a cognitive task consisting of serial subtraction by 3's. Walking performance is quantified using distance covered during the one-minute period. When wearable sensors are used, spatiotemporal gait, and/or postural sway measures may also be derived. Reduced walking distance and/or altered gait parameters reflect greater dual-task interference.
