Clinical History as a Screening Test for Ankylosing Spondylitis

JAMA. 1977;237(24):2613-2614. doi:10.1001/jama.1977.03270510035017
Abstract

A controlled study of 138 subjects demonstrated that the clinical history may be sensitive (95%) and specific (85%) in the differential diagnosis of ankylosing spondylitis when reliance on five specific historic features is made.

Back pain that is insidious in onset, in a patient younger than 40 years, persisting for at least three months, associated with morning stiffness and improving with exercise is characteristic of inflammatory spinal disease.
