Stability of motor impairment in children with cerebral palsy
Bibliographic record
Abstract
Classification of the quality and topographical pattern of motor impairment is used to describe cerebral palsy (CP). As an adjunct to a study characterizing the quality of life and participation of school-age children with C P, initial and follow-up classification of CP were compared. A cohort of 93 children (58 males, 35 females) were initially assessed at a mean age of 2 years 6 months (SD 2y 2mo) and re-assessed at 9 years 4 months (SD 2y 2mo) with a mean interval of 6 years 6 months (SD 2y 4mo) between assessments. Sixty children had Gross Motor Function Classification System levels I-III. All but one of the children were still classified has having CP at follow-up. Type of CP documented remained constant in 67 children (72%; 95% confidence interval 62-80). Clinical factors that were statistically significant (p<0.05) as possible predictors of CP subtype change were original classification of a non-spastic subtype or a non-spastic quadriparetic subtype. Change in CP subtype occurs in an appreciable minority of children with CP, which is likely to reflect a combination of intrinsic and extrinsic influences. Such change may challenge efforts to monitor the effects of interventions in this population.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
