Short-Term Natural Recovery of Ankle Sprains Following Discharge From Emergency Departments
Bibliographic record
Abstract
STUDY DESIGN: Prospective cohort study. OBJECTIVES: To examine the natural recovery from grade I and II ankle injuries over a 1-month period. BACKGROUND: There is a high rate of injury recurrence and persistence of symptoms following ankle sprains, suggesting that these injuries may not be adequately managed. However, little is known about the recovery process after discharge from emergency departments. METHODS AND MEASURES: Clinical assessment of ankle swelling, strength, and joint mobility and laboratory assessment of peak torque and joint range of motion (ROM) were performed 4 and 30 days following initial clinical assessment in the emergency department. Analyses for repeated measures determined change over time and differences between injured and noninjured ankles. Self-assessed ankle function was evaluated on day 4 and day 30, and its relationship to clinical and laboratory assessments determined. RESULTS: Forty-six subjects entered the study and complete datasets were obtained from 28. Significant swelling, weakness, and mobility restrictions were evident on initial assessment. Symptoms improved over time and, while clinical variables were normal by day 30, laboratory assessment indicated weakness of plantar flexors and limited active and passive ROM at 1 month. Swelling and reduced passive ROM were associated with overall function and limitations in sports and recreation activities, as well as quality of life 1 month postinjury. CONCLUSION: Clinically assessed strength and ankle dorsiflexion mobility suggested full recovery at 1 month post injury, yet more sensitive measures of ankle impairment and performance detected residual deficits. Persistent impairment and incomplete recovery of self-assessed function suggest the need for management beyond standard emergency department care. Associations between impairment measures and function may provide guidance for treatment intervention.

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.
