Feasibility of a postacute structured aerobic exercise intervention following sport concussion in symptomatic adolescents: a randomised controlled study
Bibliographic record
Abstract
OBJECTIVE: The utility of structured exercise for rehabilitation purposes early in the postacute phase (ie, beyond the initial 24-48 hours of advised rest) following sport-related concussion (SRC) remains largely unexplored. This study examined the feasibility of implementing a standardised aerobic exercise (AE) intervention in the postacute stage of SRC recovery in a sample of adolescent students with SRC compared with usual care. METHODS: Symptomatic adolescents with SRC were randomised to one of two groups: Aerobic Exercise (n=8) or Usual Care (n=7). The AE intervention, beginning on day 6 postinjury, comprised eight sessions with progressive increases in intensity and duration on a cycle ergometer. Usual care consisted of rest followed by physician-advised progressions in activity levels in an unsupervised setting. All participants were evaluated by physician at weeks 1, 2, 3 and 4 postconcussion. Outcome measures included: (1) Intervention feasibility: symptom status pre-post exercise sessions and completion of intervention and (2) Clinical recovery: symptom status at weeks 1, 2, 3 and 4 postinjury and medical clearance date. RESULTS: All participants completed the exercise sessions as part of the AE intervention and symptom exacerbation was not associated with any exercise session. The AE group experienced greater symptom resolution compared with the Usual Care Group across the recovery timeline. CONCLUSION: A structured AE protocol appears to be safe and feasible to administer in the postacute stage of SRC recovery in adolescents and should be explored as part of a full Phase III Clinical Trial.

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.
