Despite the angular changes in the hands, their manifestations are reversible. The prevalence of people with Systemic Lupus Erythematosus (SLE) who develop into AJ ranges from 3 to 5% of the population. It is not known whether the activities of daily living and the excessive joint load in the dominant hand can cause a greater joint deformity in patients with AJ. Objective: to evaluate whether the dominance of hand use would influence the degree of deformity and joint amplitude in patients with AJ associated with SLE. Methods: cross-sectional study. The instruments used were: JAMAR® manual analog hydraulic dynamometer; the Inches® brand finger goniometer and the Carci® brand universal goniometer. Results: Conclusion: People with AJ associated with SLE were more likely to experience deformation in the dominant hand and in individuals who performed high manual activitiesAcesso AbertoLúpus eritematoso sistêmicoArtropatia de JaccoudDominânciaDeformidade em mãosSystemic erythematomous lupusArthropathy of JaccoudDominanceDeformity in handsTrabalho de Conclusão de CursoCiências da SaúdeFisioterapia
