figure-four test

Patrick’s test

A clinical test used to identify the source of pain (ilipsoas, groin or inguinal, or sacroiliac joint).
The patient lies supine with the foot on the involved side crossed over the opposite thigh (figure-4 position) and the leg resting in the full external rotation. The examiner places one hand on the opposite ASIS, the other on the medial aspect of the flexed knee, and applies excess pressure on both.
Positive test
• Inability to lower the flexed thigh down to the level of the leg on the table implies iliopsoas tightness.
• Hip joint pain implies groin or inguinal involvement.
• Sacroiliac pain implies sacroiliac joint pathology (evoked by applying the overpressure on the sacroiliac area).
