Abstract
Background: Individuals with Parkinson disease (PD) may have a flexed posture, but only axial postural abnormalities (PAs) are generally investigated. Purpose: The objective was to verify if PAs of the axial and appendicular skeleton observed in PD occur in an interrelated manner to maintain balance and physical function. Methods: A cross-sectional observational study. Sixty-nine individuals with PD were evaluated by computerized photogrammetry. The MDS-UPDRS scale was used to analyze the physical function and the Mini-BESTest to assess balance. To determine the relationship between PAs and clinical aspects, multiple linear regression analysis was performed, setting age and levodopa equivalent dose as covariates. Results: The anterior trunk inclination angles were significantly correlated with the flexion angles of the elbows, hips and knees (p˂0.01). Larger head flexion was correlated with worsening physical function (p=0.013) and gait (p=0.043); greater trunk, hip and knee flexion were correlated with reduced postural instability (p˂0.05), and greater knee flexion was correlated with improvements in gait deficits (p=0.013). Conclusion: Postural abnormalities in the axial and appendicular joints of people with PD appear to occur in an organized and interrelated manner as a body compensation used to improve physical function and reduce balance and gait deficits.

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
