Method:
1. Ask the patient to lie supine on the exam table.
2. Place the foot of the affected side on the opposite knee.
3. Pain in the groin area indicates a problem with the hip and not the spine.
4. Press down gently but firmly on the flexed knee and the opposite anterior superior iliac crest.
5. Pain in the sacroiliac area indicates a problem with the sacroiliac joints.
