PURPOSE: This study was designed to examine the functional loss in ankylosing spondylitis and explore the relationship between disability and various factors such as age, disease duration, disease activity, spinal mobility, chest expansion, peripheral joint involvement, radiological changes, and psychosocial well-being. METHOD: Forty-two patients were included in this cross-sectional study. RESULTS: The results showed that 37 patients had mild to moderate disability, two patients had severe disability, and three patients did not report any functional loss. Spearman correlation analyses showed that disability was strongly correlated with spinal mobility measures, disease activity measures, and disease duration. Also, patients with peripheral joint involvement had greater disability. When the predictive effect of five independent variables was studied by multiple regression analysis, it was found that the most powerful predictors of functional loss in AS patients were cervical rotation, modified Schober's test, and pain. CONCLUSIONS: These data suggest that functional consequences of AS are constituted by multiple impairments and each needs to be managed by an integrated physiatric approach.
