Abstract

Abstract: Objective: The aim was to examine hand function and performance in activities of daily living (ADL) in patients with SLE vs healthy controls, and any associations with demographic and disease-related characteristics. Methods: Hand function (grip strength, pinch strength and dexterity) and ADL performance were evaluated in 240 patients with SLE and 122 age- and biological sex-matched healthy controls. Grip strength, pinch strength and dexterity were measured by Jamar dynamometer, pinch gauge and Purdue pegboard test, respectively. Self-reported ADL performance was assessed by disabilities of the arm, shoulder and hand (DASH) and HAQ. Regression analysis was performed to assess the determinants of hand dysfunction. Results: All hand function and ADL performance variables were significantly impaired in the entire SLE cohort and the subgroup of patients achieving lupus low disease activity state (LLDAS; n = 157) compared with healthy subjects ( P < 0.05). Joint pain, often underestimated in SLE, was the major determinant of hand function and ADL performance in multiple regression models. In addition, age was correlated with grip strength and Purdue scores, gender with grip strength, arthritis with DASH and HAQ, and use of immunosuppressives with DASH, HAQ and grip strength. Likewise, in patients in LLDAS, painful joints were correlated with DASH and HAQ, age with grip strength and Purdue ( P < 0.001), gender with grip strength, and immunosuppressives with HAQ and grip strength. Conclusion: Hand function and performance of daily activities are significantly impaired in SLE, even in patients who achieve LLDAS, suggesting the need for their evaluation and management in clinical practice.
