Execution
- 1Position the patient prone on the table.
- 2Palpate the ASIS from underneath the pelvis with the palm or fingers on the tested side.
- 3Ask the patient to extend the hip approximately 15° so the foot lifts just off the table.
- 4Palpate for anterior innominate movement during the active hip extension.
- 5Repeat on the opposite side and compare pain, movement quality, and side-to-side motion.
Positive outcome
The test is positive when the expected innominate movement is absent, reduced, painful, or clearly asymmetrical compared with the opposite side. It is intended to identify SIJ movement dysfunction rather than intra-articular SIJ pain. The result should be interpreted with caution because validation is limited.

CommentThe Shimpi test reports better numbers than older motion palpation tests, but the evidence base is small and methodologically less mature than SIJ pain provocation clusters. It is not a Magee-traditional core test in the same way as Gillet or joint play movements. Use it as an exploratory movement-dysfunction screen, not as confirmation of SIJ pain.
