The Headaches of Developing a Concussion App for Youth
Bibliographic record
Abstract
This descriptive manuscript describes challenges, solutions, and recommendations to provide a supportive framework for clinician researchers striving to develop a clinical app. The Back2Play app aims to support youth in concussion recovery through mobile health monitoring. Developed in Phase 1 of a randomized control trial, the app intends to prevent re-injury and improve recovery by integrating evidence-based return-to-school and activity guidelines with biological monitoring. Methods outline the stages of successful app development. Identified challenges include defining app requirements, database hosting, development, and legal procedures. Results of usability testing show that the Back2Play app was highly acceptable to 66% of youth and none found it unacceptable. Successful clinical app development hinges on understanding the scope of the app, data management and exportation. Adequate funds should also be allocated for potential delays. These recommendations provide a framework for clinical researchers hoping to develop a clinical app that achieves their envisioned outcome.

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.
