BackgroundRheumatoid arthritis (RA) is a systemic, inflammatory disease that causes pain, joint destruction and disability. RA affects the function of the hand and upper extremities; function deteriorates as the disease progresses and affects independence. Unsupported upper-limb exercise (UULEX) test was developed to evaluate upper extremity function and endurance in individuals with Chronic Obstructive Pulmonery Disease. It is suggested that this test can be used in other clinical cases with arm disabilities.ObjectivesThe aim of this study was to examine whether the UULEX Test is valid and reliable in individuals with RA.Methods71 individuals with RA (15 male, 56 female) with an average age of 52.15 10.11 were included in the study. The Intraclass Correlation Coefficient (ICC) was used to assess the reliability of the UULEX test. Each individual was assessed by one physiotherapists in two different sessions, a week apart. The correlations of the UULEX test with Disabilities Arm, Shoulder and Hand (DASH), Health Assessment Questionnare (HAQ), 30 sec Push Up Test and 6 Peg Board Ring Test were assessed for concurrent validity.ResultsIntrarater reliability of final level, final weight, duration of the UULEX Test were determined to be excellent (ICC= 0.922, 0.960, 0.958). A moderate to excellent correlation was found between UULEX Test and DASH, HAQ, 30 sec Push Up Test and 6 Peg Board Ring Test (p<0.05).ConclusionThe results of this study showed that the UULEX test is a valid and reliable method in the assessment of upper extremity endurance in individuals with RA.References[1] - Manning VL, Hurley MV, Scott DL, Coker B, Choy E.
