Measures of outcome in ankylosing spondylitis and other spondyloarthritides.

This chapter describes core sets that can be used in the assessment of ankylosing spondylitis and other spondyloarthritides. Various core sets are described for the evaluation of disease-controlling antirheumatic therapy, symptom-modifying antirheumatic drugs and physical therapy, or for use in clinical record keeping. These core sets describe domains and also give advice on specific instruments. The value of spinal mobility and acute-phase reactants in the assessment of ankylosing spondylitis in AS are described in more detail. The available radiological scoring methods are discussed.
