Abstract
OBJECTIVES: To describe mechanographic tests that can be performed by patients with a range of functional abilities and to assess the reproducibility of test results in healthy adults and children. METHODS: Fifteen adults and 13 children underwent two separate sessions, one week apart. Participants performed five different tests in both sessions: Multiple one-legged hopping, multiple two-legged hopping, single two-legged jump, heel-rise test, chair-rise test. All measurements were recorded with a portable force platform. RESULTS: The main outcome measures of each test (peak force relative to body weight or peak power relative to body weight, depending on the test) showed no systematic differences between Session 1 and 2 for any of the test results. Coefficients of variation for the suggested main outcome parameters ranged between 3.4% and 7.5% for multiple one-legged hopping, multiple two-legged hopping, single two-legged jump and the heel-rise test, but were higher for the chair-rise test (8.0% in adults, 15.6% in children). CONCLUSIONS: The five mechanographic tests assessed in the present study yield reproducible outcome measures in healthy subjects. It is justified to evaluate the usefulness of these tests in different patient populations.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
