Sacroiliac Joint


The purpose of this review is to explore the literature regarding sacroiliac joint motion in an attempt to ascertain the extent of movement possible, to describe relevant sacroiliac joint anatomy and joint function, and to review assessment and treatment techniques used with sacroiliac joint dysfunction. Sacroiliac joint motion and function have been the subject of much controversy among clinicians who treat low back pain. Because of its location, orientation, and morphology, the sacroiliac joint is a difficult joint to visualize clearly with radiographic procedures, which increases the problems in diagnosis of sacroiliac joint pathology. Although the arthrokinematics of the sacroiliac joint remain controversial, clinicians now generally agree that a small but significant amount of motion does occur at the sacroiliac joints. Many different descriptions of sacroiliac joint motion exist. Consequently, many different clinical tests are used to evaluate the joint. Palpation tests for sacroiliac joint dysfunction have shown poor intertester reliability, while provocation tests exhibit good intertester. Treatment techniques used by clinicians include modalities such as ice, massage, and electrical stimulation to reduce pain. Muscle energy techniques and mobilizations are used to correct sacroiliac joint positional faults. It is important to bear in mind that the effectiveness of these treatments is not well documented.
