Validity of the 6-Minute Pegboard and Ring Test in Parkinson's Patients

Investigation of the Validity and Reliability of the 6-Minute Pegboard and Ring Test in Parkinson's Patients for Upper Extremity Endurance Assessments

Tests used to assess upper extremity endurance in Parkinson's patients are limited. This study aimed to investigate whether the 6-Minute Pegboard and Ring Test (6-MPRT), which has been validated in many respiratory disease groups in previous studies, is an endurance assessment battery that can also be used in Parkinson's patients. 6-MPRT, Weight Lifting Test, and 30-Second Arm Curl Test will be applied in the assessments. Assessments will be made twice on the same day by two different evaluators, 1 hour apart. After the first evaluation, the patient will be called for the second time 2 days later, and the same procedure will be repeated.

Inclusion Criteria:

• Hoehn & Yahr staging ≤3 points,
• Individuals who have not undergone a rehabilitation program of at least 20 days in the last 6 months,
• Those with full upper extremity shoulder flexion and abduction active joint range of motion.

Exclusion Criteria:

• Those with severe heart disease such as heart failure, cardiac arrhythmia, hypertension,
• People with any orthopedic problem that will affect the upper extremity,
• Having a secondary neurological disease diagnosis,
• Having vision impairment that may affect measurement methods (not corrected by glasses),
• Having a cognitive disease that may cause difficulty in following the researchers' commands,
• Those who had changes in their medical use during the test (dose increase/decrease, drug change
