During the FABER protocol, which structure is stabilized?

• A. Patella
• B. Greater trochanter
• C. Calcaneus
• D. Opposite ASIS

Answer: (D)

Stabilizing the opposite ASIS fixes the pelvis so that movement during the FABER maneuver comes from the hip and sacroiliac region, not from pelvic motion. In this test, the leg is flexed, abducted, and externally rotated with the foot resting on the opposite knee, while the clinician holds the contralateral ASIS to prevent pelvic tilt or rotation as they apply gentle pressure. This setup isolates the hip/SI joints to help pinpoint where pain or dysfunction originates. The other structures listed aren’t used as the stabilization anchor: the patella and calcaneus are part of the knee and foot, and the greater trochanter isn’t the stabilization point in this protocol.
