Stretch reflex and learning in a ballet class for individuals with cerebral palsy
Bibliographic record
Abstract
Abstract This study reports changes in the stretch reflex and clinical motor sores in individuals with mixed spastic and dyskinetic cerebral palsy (CP) after learning in a targeted ballet class. Four individuals (ages 7 to 22 years) completed a personalized one-hour targeted ballet class twice per week for six weeks. Quantitative measures of the elbow or ankle stretch reflex were obtained using electromyography and electrogoniometry, along with clinical assessments of spasticity and dyskinesia. The joint angle of stretch reflex onset varied for similar velocities of stretch across participants and its variability decreased after the class. Clinical measures revealed improvements in balance, selective motor control, range of motion, and upper limb function. The variability of the stretch reflex may be attributed to the dyskinetic component of the mixed CP presentations. Changes in stretch reflex and improvements in clinical scores suggest that learning through the ballet class may be beneficial to everyday function. The study was registered in the Clinical Trials Protocol Registration and Results System (NCT04237506, January 17, 2020.)

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.
