Sacroiliac Joint (SI) Pain

The sacroiliac (SI) joint is made up of the sacrum articulating on the ilium.  It is surrounded by thick fibrous ligaments, which help to make it a very stable joint.  However, whether it is from repetitive, prolonged stress, or a traumatic event, the SI joint can move enough to become a source of pain. It is often felt near or below the belt line, and cause radiating symptoms into the posterior hip or groin. It is important to differentiate SI pain from radiating lumbar pain.  Our staff at Portland Physical Therapy have several years of experience treating low back pain, and use specific test to determine where the symptoms are originating from, so they are able to create a specific plan for rehabilitation.

Associated Symptoms:

  • Low back pain (at or below beltline)
  • Pain that radiates into buttock, groin
  • Pain with walking, standing, bending
  • Pain with sitting
