Abstract

fetched live from OpenAlex

Objective We undertook an exploratory, interim analysis examining changes in ocular vergence using digital vestibular-ocular motor screening (VOMS) assessment from baseline to post-concussion. Design Prospective observation. Setting Professional and amateur sport teams. Participants 379 (96 female) Australian rules footballers, aged over 18 years, male and female competitions. Interventions (or Assessment of Risk Factors) Ocular vergence from the following VOMS assessment (NeuroFlex Inc., Canada); smooth pursuit eye tracking (head free and head fixed) vestibular ocular reflex (VOR) (horizontal and vertical) saccades and antisaccades optokinetic nystagmus Outcome Measures VOMS assessments occurred at baseline (pre-season) and following a concussion (with 48 hours). Changes examined with a paired-samples, one-tailed t-test, with significance at 0.05. Two analyses were performed (table 1); ocular vergence for all protocols three tests focusing on ‘central’ measures: smooth pursuit head-fixed, horizontal VOR, and saccades Main Results At the time of analysis, there were 14 concussions (6 females, age 22 [range 18–29]). Changes in mean ocular vergence for all tests trended towards significance (t13 = 1.6, p = 0.067). There was significantly increased divergence from baseline to post-concussion (t13 = 2.1, p = 0.029) for the central tests. Conclusions There was a trend towards a significant increase in mean ocular divergence after a concussion. For ‘central’ VOMS tests, ocular divergence significantly increased from baseline to post-concussion.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
