FUNCTIONAL EVALUATION OF HANDS IN PEOPLE WITH AND WITHOUT ARTHROPATHY OF JACCOUD ASSOCIATED WITH LÚPUS

Abstract

Introduction: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of a diffuse nature, which causes, among other factors, joint involvement Jaccoud arthropathy (AJ) is a reversible deforming inflammation that occurs in the proximal joints, Frequently seen in upper limbs. The epidemiological prevalence of AJ is 5% for SLE patients. Poor alignment or loss of strength can limit movement, generate compensations and joint overloads. Early functional diagnosis may help reduce the installation of joint deformities. Objective: To compare the range of motion and palmar grip strength in people with and without AJ associated with SLE. Methods: A cross-sectional study where patients were allocated to two groups: diagnosed with SLE and diagnosed with SLE associated with AJ. The instruments used: dynamometer, finger goniometer and the universal goniometer. Results: 67 women with SLE participated in the study, of which 32 had AJ. The sociodemographic and clinical characteristics of the groups were considered homogeneous for the analyzed variables. A significant difference was observed between groups, except for the extent of interphalangeal extension of the first right mandibular (p = 0.073), distal interphalangeal of the fourth left (p = 0.083) and distal interphalangeal of the first left mandibular (p = 0.435 ). Conclusion: People with AJ associated with SLE had higher joint amplitude and lower palmar grip strength compared to those with SLE alone. These results suggest that there is still a need for complementary studies to observe the functionality of these people's hands.
