The Validity and Reliability of Provocation Tests in the Diagnosis of Sacroiliac Joint Dysfunction.

Abstract

Although sacroiliac joint dysfunction (SIJD) is generally regarded as a source of lumbar pain, its anatomical position and the absence of a diagnostic 'gold standard' lead to difficulties at examination and differential diagnosis. However, since sacroiliac (SI) joint blocks only provide information about pathologies of joint origin and since SIJD developing secondary to pathologies in structures around the joint can be missed. Provocation and palpation tests also need to be used in diagnosis.
