Abstract

fetched live from OpenAlex

Objective: The ability to accurately identify concussions and assess recovery is essential to protect individuals from experiencing negative consequences regarding premature return-to-play. To date, there is no “gold” standard of concussion diagnosis nor method to track the recovery period. Instead, clinicians rely on symptom checklists and simple tests to inform clinical decisions. However, the timing and frequency of objective measurements to screen for impairment and monitor recovery remains underexamined. This study examines the potential of a rapid (5-min) sensor-based balance measurement on a habitual (i.e., pre/post-practice) schedule to screen for concussions. Design: A pilot study using a repeated observation design. Methods: Five varsity hockey players (3 males, 2 females) were recruited for a 9-week study. Each athlete was tested prior to and after practice using an IMU, performing a modified Balance Error Scoring System (BESS) test. Results: Sampled data used to estimate individual beta distributions indicates significant individual differences in balance behaviour across a range of metrics. Conclusions: This study supports the need for individualized baseline profiles for balance in order to achieve higher accuracy and sensitivity in concussion detection. Serial, habitual testing is recommended to enable concussion detection from objective measures with higher accuracy and sensitivity during sideline assessments.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
