Rheumatoid arthritis (RA) is a chronic disease which affects the performance of the upper extremities. There is no method to evaluate the specific upper extremity endurance of individuals with this disease. The unsupported upper-limb exercise test (UULEX) is a performance test that evaluates upper extremity performance (functionality and endurance). ⋯ The results of this study showed that UULEX test is a valid and reliable method for the assessment of upper extremity performance in individuals with RA.
