Sacroiliac

The sacroiliac joints sit at the base of your spine, where it meets the pelvis. They transfer load between your upper body and legs, and when they become irritated they can cause pain low in the back, buttock, or hip — often on one side, and sometimes worse with standing, stairs, or turning in bed. Pregnancy, injury, and uneven loading are common triggers.

Physiotherapy helps by settling the irritated joint, improving how your pelvis and hips move and share load, and building strength for lasting relief. Here you'll find practical assessment and management guidance for sacroiliac joint pain and related lumbopelvic problems — evidence-based for clinicians and clear for patients.
