Concussions in Ice Hockey : baseline Testing, Reporting Accuracy, and Cervical Functioning
Bibliographic record
Abstract
The purpose of this study was threefold: firstly, to demonstrate the utility of the SCAT2 as both a baseline measurement and a tool to aid in the decision making process following the occurrence of a concussion; secondly, to assess the accuracy of reporting and/or relaying a diagnosis of a concussion; and finally to attempt to measure a relationship between cervical spine functioning and past concussion occurrence. Eighty hockey players were assessed for cognitive, neuropsychological, and physical measures pertaining to concussive injuries within ice hockey. The results of the study showed a marked underreporting of concussions due to either fear of reporting, misdiagnosis, or simple lack of knowledge. The SCAT2 is demonstrated to be a useful and cost-effective tool for use as a baseline measure or for a means of following up post-injury. No significant findings appeared with regards to cervical functioning and past concussive injuries; recommendations for future research are offered.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
