Measuring steady-state oxygen uptake during the 6-min walk test in adults with cerebral palsy
Bibliographic record
Abstract
This study evaluated the feasibility of measuring steady-state oxygen uptake (VO2) during the 6-min walk test (6MWT) in adults with cerebral palsy (CP) who walk without support and whether there is construct validity for net 6MWT VO2 as a measure of their walking ability. Cardiorespiratory variables were assessed at rest and during the 6MWT in 15, independently ambulatory adults, 21-41 years old, with CP. The Gross Motor Function Measure dimensions D and E (GMFM-D and GMFM-E) quantified walking-related skills. Steady-state VO2 was achieved during the 6MWT. After controlling for body mass and speed, the net 6MWT VO2 was strongly related to GMFM-D (r=-0.58, ρ=0.03) and GMFM-E scores (r=-0.66, ρ=0.007). We conclude that for young adults with CP who walk without support, it is feasible to measure steady-state VO2 during the 6MWT and that the net 6MWT VO2 has construct validity as a measure of walking ability.

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.
