Which findings are used to assess sacroiliac joint dysfunction on examination?

Understanding sacroiliac joint dysfunction relies on combining multiple, complementary examination findings that reflect SI joint motion and pelvic alignment. The standing flexion test assesses how the pelvis moves when you bend forward. You observe the PSISs as the patient flexes; the side that moves cephalad or more than the other indicates dysfunction at the corresponding SI joint. Visually and palpatorily checking for asymmetry of the PSIS and iliac crests provides another clue. A noticeable height difference or level discrepancy suggests abnormal SI joint motion or pelvic tilt on one side. The spring test evaluates sacral motion by applying a gentle springing force to the sacral base. If the sacrum doesn’t spring normally (a positive spring test), this indicates restricted sacral motion consistent with sacral extension or related SI dysfunction. Because these findings together are used to assess SI joint dysfunction, all of the above are applicable.
