SAT0719-HPR Performance-based physical function measure was more sensitive to detect responders than self-reported measure after a physical therapy exercise intervention in patients with axial spondyloarthritis

Abstract

Physical function is regarded as an important outcome in axial spondyloarthritis (axSpA) and the self-reported questionnaire Bath Ankylosing Spondylitis Functional Index (BASFI) is recommended for the evaluation. How- ever, it is shown that BASFI may not be sufficiently sensitive to detect changes after physical therapy. Based on BASFI a disease-specific performance-based measure has been developed; the Ankylosing Spondylitis Performance-based Improvement (ASPI).
