Examining Physical Activity, Adiposity, and Function in Youth with and without Spastic Cerebral Palsy
Bibliographic record
Abstract
Objectives: To examine physical activity (PA), body composition, balance, and strength in youth (ages 10-18) with cerebral palsy (CP), compared to age- and sex-matched typically developing (TD) peers. Methods: Thirty youth with CP [gross motor function classification system (GMFCS) levels I-III; 20 males], were matched to TD youth. PA (minutes in sedentary, light, and moderate-vigorous) was measured using ActiGraph accelerometers. Body composition (fat and lean mass indices) was assessed by dual-energy x-ray absorptiometry. Center of pressure (total path length and 95% ellipse area) on two force plates represented balance. Lower-extremity strength was measured using hand-held dynamometry. Results: Youth with CP, GMFCS levels II or III, achieved less moderate-vigorous PA, were more sedentary, weaker with all lower-extremity muscle groups, had lower lean mass indices, and had larger 95% ellipse areas than TD youth. Conclusions: GMFCS level appeared to impact the severity of activity limitations and of body structure and functional impairments.

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.
