Execution:
- Patient is in supine lying position and the examiner is standing on the affected side
- The patient is asked to flex the ipsilateral knee with the medial side of the heel against the other knee
- While the examiner fixates the contralateral anterior superior iliac spine (ASIS), the patient lowers the ipsilateral knee towards the treatment table as far as possible, while the plantar side of the foot remains in contact with the other knee
- At last, the examiner applies overpressure at the ipsilateral knee of 15kg for 5 seconds
Positive Outcome: Patient’s familiar pain (usually in the buttock, lower lumbar spine, posterolateral thigh and groin) is reproduced
