Abstract
Background: Pain is a frequent non-motor symptom in patients with Parkinson’s disease (PD) and appears to be related to low levels of dopamine. This study describes the characteristics of chronic pain in a group of PD patients undergoing levodopa therapy. Methods: This was a cross-sectional study. The pain was assessed in 21 selected PD patients with chronic pain using several scales and instruments. Changes in pain response from levodopa use (wearing-off phenomenon) were monitored. Results: The most prevalent type of pain was nociceptive (71.4%), musculoskeletal and dystonic, but neuropathic pain accounted for the highest pain score according to the Parkinson’s Disease Pain Classification System (45.5±30.08). Patients with neuropathic, nociplastic, or nociceptive pain upon wearing-off were those who responded to levodopa (p=0.999). According to the McGill questionnaire, patients with pain upon wearing-off had higher scores in the affective/motivational dimension (p=0.022). Conclusion: Using a new pain classification and scoring tool, this study corroborates a good response to levodopa in PD-related pain.

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
