In Faber's test, what is the patient position and examiner action?

• A. Supine, figure 4 position; push down on knee
• B. Seated; extend knee
• C. Prone; lift knee
• D. Standing; rotate hip

Answer: (A)

This test checks whether hip joint pathology or sacroiliac joint pathology is producing pain by putting the leg in a figure-4 position and pressing the knee downward. The patient lies on their back with the leg flexed, abducted, and externally rotated so the ankle rests over the opposite knee (the figure-4 position). The examiner gently presses down on the knee while stabilizing the pelvis. A positive result helps distinguish the source of pain: groin pain suggests hip joint involvement, while pain in the buttock or SI region suggests sacroiliac involvement. This description matches supine with a figure-4 position and downward knee pressure. The other options describe different positions and actions not used for this test.
