What is the effect of direct compression or distraction during SIJ evaluation?

Direct compression or distraction tests load the sacroiliac joints by stressing the joint surfaces, capsule, and supporting ligaments. If the SI joint is irritated or unstable, this loading tends to provoke or intensify pain because the structures within or around the joint become sensitized to stretch and compression. Because individual joint irritability varies, these maneuvers do not always reproduce pain in every patient, nor are they designed to reduce pain, but they can increase it when the SI joint is the pain source.
