Learning More from Finger Tapping in Parkinson's Disease: Up and Down from Dyskinesia to Bradykinesia
Bibliographic record
Abstract
The finger tapping test evaluates bradykinesia, focusing on decrement in rate, amplitude, or both with repetitive action. Vertical positioning of the hands during this task may also be clinically relevant. We developed a "TAP score," measuring the vertical level above the lap where the patient performs the finger tapping ranging from 1 (task performed with the hand close to the lap) to 4 (above the head). In this pilot study, we retrospectively applied the TAP score in addition to usual motor scales during acute levodopa challenge in 123 PD patients (of whom 88 presented l-dopa-induced dyskinesia [LID]). TAP ON was higher than TAP OFF. Patients with LID presented higher TAP ON. TAP ON was related to LID severity, whereas TAP OFF was inversely related to the OFF motor symptoms. The TAP score may be a measure of proximal movement amplitude representing an easy method to evaluate defective or excessive motor output in patients with advanced disease.

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.
