Pen and paper: a new hope for Parkinson's hand tremors?
NCT ID NCT07399522
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested whether doing special handwriting exercises at home for 12 weeks could improve hand function in people with Parkinson's disease. Fifty-three participants were split into two groups: one did the handwriting program, the other did not. The main goal was to see if the exercises improved manual dexterity, measured by a pegboard test.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Calligraphic handwriting exercise program
- What this could lead to
- If it works, this could offer a simple, home-based way to improve hand function and daily activities for people with Parkinson's disease.
- What could go wrong
- This is a small, early-stage trial with only 53 participants. The exercises may not lead to meaningful improvements, and results may not apply to all Parkinson's patients.

INCLUSION CRITERIA: * Patients aged 40 to 80 years * Clinical diagnosis of Parkinson's disease according to the UK Brain Bank criteria. * Hoehn and Yahr stage 1 to 4 * Assessed in the ON-medication state (approximately 90 minutes after levodopa intake) * Stable antiparkinsonian treatment for at least 4 weeks prior to study entry and maintained throughout the study period EXCLUSION CRITERIA: * Parkinson's disease-related dementia, defined as a Montreal Cognitive Assessment (MoCA) score \< 21 * Upper limb comorbidities unrelated to Parkinson's disease that could interfere ith exercise performance (e.g., arthritis, recent fractures, stroke sequelae, or peripheral neuropathy) * Severe tremor or severe dyskinesias affecting the dominant hand, defined as: * a score ≥ 3 on UPDRS-III items 20 or 22, or * score ≥ 2 on UPDRS-IV item 33
