Literature Review: 6PBRT and UULEX as an Unsupported Upper Limb test in People with Respiratory and Musculoskeletal disability

Upper limb (UL) function is essential for daily activities, yet it is often overlooked in rehabilitation programs for individuals with respiratory and musculoskeletal disabilities. The six-minute pegboard and ring test (6PBRT) and the unsupported upper limb exercise test (UULEX) are two validated tools for assessing UL functional capacity. These tests simulate daily UL movements, measuring endurance, strength, and coordination, particularly in patients with chronic obstructive pulmonary disease (COPD), rheumatoid arthritis, asthma, bronchiectasis, interstitial lung disease, and pulmonary hypertension. Research suggests that UL exercises improve dyspnea, endurance, and activities of daily living (ADLs), supporting their integration into rehabilitation programs. This review explores the methodology, clinical applications, and benefits of 6PBRT and UULEX, highlighting their role in comprehensive patient assessment and functional rehabilitation.
