The study aims to test a new way to check how well people with Parkinson's disease can use their arms. Parkinson's disease is a condition that affects movement, making it difficult for people to control their muscles. The study will use the 6-Minute Pegboard and Ring Test (6-MPRT) to measure how long people can use their arms without getting tired. Other tests include the Weight Lifting Test and 30-Second Arm Curl Test. Participants will be tested twice in one day, one hour apart, and again two days later.
- Commitment: 2 visits, each with 2 assessments.
- Eligibility: Must have Parkinson's with certain movement abilities.
- Exclusions: Heart issues or other conditions affecting arms or vision.
