Parkinson's study: does body sway affect hand dexterity?
NCT ID NCT07182487
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 80 people with Parkinson's to see if there is a link between how much their trunk sways and how well they can use their hands. Researchers used a motion sensor to measure trunk sway and a pegboard test to measure hand dexterity. The goal is to understand if better trunk control might help with fine hand movements.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If the link is confirmed, it could help design better physical therapy that targets trunk stability to improve hand function in Parkinson's.
- What could go wrong
- This is a small, completed observational study, not a treatment trial. It only measures relationships, so it cannot prove that improving trunk sway will improve hand skills.

Inclusion Criteria: * Healthy individuals aged 40-75 years, diagnosed with idiopathic PD according to the UK Parkinson's Disease Association Brain Bank criteria by a specialist neurologist, with a Modified Hoehn \& Yahr (m-HY) scale stage ≤4, and with a Mini Mental State Examination score of ≥22 for those with training and ≥18 for those without training, and with no known disease, volunteered to participate in the study. * Individuals with no other known neurological and/or systemic disease * Individuals without any upper extremity contractures Exclusion Criteria: * Individuals with severe balance and walking difficulties * Individuals with diagnosed and/or treated psychiatric illnesses who are considered unable to complete the required tests * Those taking neuroleptic medications or antidepressants * Individuals with orthopedic conditions that interfere with manual dexterity tests, such as severe dyskinesia, carpal tunnel syndrome, tendon injuries, or finger amputations; rheumatological diseases such as rheumatoid arthritis and osteoarthritis; and individuals with any neurological disease other than PD
