Abstract
OBJECTIVE: To test the hypothesis that patients with chronic exertional compartment syndrome (CECS) of the anterior leg compartment have an increased anterior compartment thickness (ACT) compared with control subjects after exertion using ultrasound. DESIGN: Prospective comparison study. SETTING: Diagnostic imaging department of a tertiary care hospital. PATIENTS: Four patients with CECS and 9 control subjects. INTERVENTIONS: Patients with CECS and control subjects ran on a treadmill for up to 10 minutes. Anterior compartment thickness (both groups) and anterior compartment pressure (CECS patients) were measured before exertion and at scheduled intervals after exertion. MAIN OUTCOME MEASURES: Anterior compartment thickness, percentage change in ACT from rest, and compartment pressure. RESULTS: Anterior compartment pressures were diagnostic of CECS using the modified Pedowitz criteria in patients with CECS. Mean percentage change in ACT from rest in patients with CECS versus control subjects at 0.5 minutes was 21.3% versus 6.32% [95% confidence interval (CI), 6.92-35.6 and 0.094-12.5, respectively; P = 0.011]; at 2.5 minutes, it was 24.6% versus 4.22% (95% CI, 10.7-38.5 and -1.85-10.3, respectively; P = 0.003); and at 4.5 minutes, it was 24.9% versus 5.08% (95% CI, 14.3-35.5 and -0.813-11.0, respectively; P = 0.003). Mean ACT in patients with CECS versus control subjects significantly increased after exertion (P = 0.003) at 0.5 minutes, 2.5 minutes, and 4.5 minutes. CONCLUSIONS: Ultrasonography reveals a significant increase in ACT in patients with CECS of the anterior leg compartment. Further studies are warranted to validate these findings with the goal of developing anterior leg compartment CECS ultrasound diagnostic criteria and exploring the role of using ultrasound to diagnose CECS in other compartments.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
