Correla??o entre instrumentos de avalia??o da funcionalidade e equilíbrio em pacientes com artrite reumatoide

摘要

Rheumatoid arthritis (RA) is a systemic inflammatory autoimmune disease, chronic and progressive, which can cause pain, decreased mobility, physical strength and activity, leading to changes in proprioception, postural balance and gait, which increase the risk of falls in these patients. The present study aimed to verify if there′s correlation among functionality and balance tests in RA patients. This study was conducted with a cross-section sample of 99 patients diagnosed with RA of both sexes. Assessment instruments fall risk were used: Berg Balance Scale (BBS), Test "Timed Up and Go" (TUG), 6 Minutes Walking Test (6MWT) and Short Physical Performance Battery (SPPB) or Guralnik Battery Test. Made Kolmogorov-Smirnov test for normality of distribution and Spearman correlation, with significance level of p < 0.05. Patients were 88,9% female with a mean age of 56.15 years (± 11.64). Age showed a weak correlation, but significant o that the older, worse performance on tests. The average performance of the instruments do not put these RA patients as high risk of falling, but there is no specific cut off values for this population. The instruments showed moderate to strong correlation with each other (p < 0.01). We conclude, therefore, that the physical tests are performed and correlated well represent the physical capacity of RA patients, especially among people over 41 years old and men.
