What does a positive Sacroiliac Stress Test mean?

A positive test is one in which the patient’s groin or sacroiliac joint pain is reproduced anteriorly, posteriorly, unilaterally, or bilaterally.


A positive stress test indicates the presence of inflammation, but does not give any information as to the cause.

If the test is positive in a patient who has recently fallen, there is a possibility that a fracture of the pelvis exists.

Sacroiliac joint becomes diseased in inflammatory conditions (seronegative inflammatory arthropathy), infections and fracture-dislocation. Special stress tests and other diagnostic tools can identify the pathology. Turning on bed especially in early morning hours and getting up from bed is very painful. Sometimes there can be pain on weightbearing with hamstring spasm.
