Abstract
Suprasegmental effects following selective posterior rhizotomy have been frequently reported. However, few studies have used validated functional outcome measures to report the surgical results beyond 3 years. The authors analyzed data obtained from the McGill Rhizotomy Database to determine the long-term impact of lumbosacral dorsal rhizotomy on fine motor skills. The study population comprised children with debilitating spasticity who underwent SPR and were evaluated by a multidisciplinary team preoperatively, at 6 months and 1 year postoperatively. Quantitative standardized assessments of upper extremity function were obtained using the fine motor skills section of the Peabody Developmental Motor Scales (PDMS) test. Of 70 patients who met the entry criteria for the study, 45 and 25 completed the 3- and 5-year assessments, respectively. Statistical analysis demonstrated significant improvements in grasping, hand use, eye-hand coordination, and manual dexterity at 1 year after SPR. More importantly, all improvements were maintained at 3 and 5 years following SPR. This study supports that significant improvements in upper extremity fine motor function using the PDMS evaluative measure are present after SPR and that these suprasegmental benefits are durable.

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 it
