Diagnostic Tests for Mechanical Dysfunction of the Sacroiliac Joints

Abstract

Despite almost a century of management of mechanical dysfunction of the sacroiliac joints, no testing procedures have been satisfactorily validated for diagnosis. This paper presents tests that proved to be the most reliable for the management of 57 patients referred by their GPs for treatment of back and leg pain. The patients all regained normal pain-free function after manipulation of the sacroiliac joint(s) followed by a program of modified living and progressively increased walking. The tests include a version of Gillet's test (alternate hip and knee flexion in support standing) revised by the author, passive hip rotations in supine with 90 degrees of hip and knee flexion, and palpation of the superior ligament of the symphysis pubis. This paper proposes that when performed as described, these four tests are worth validating for the diagnosis of sacroiliac joint dysfunction.
