In FABER test protocol, what should be observed for compensatory movement?

• A. Only the test knee.
• B. Forearm rotation.
• C. Ankle positions.
• D. Hip, pelvis, and lumbar spine.

Answer: (D)

FABER (Flexion, ABduction, External Rotation) places the leg in a figure-4 position, so the body commonly compensates with movement in the proximal segments to maintain that position. Observing the hip, pelvis, and lumbar spine reveals whether the compensation is coming from the hip joint or sacroiliac/lumbar region, which helps localize potential pathology. Movements limited to the knee, or distal joints like the ankle or forearm, aren’t the primary compensations in this maneuver, so they don’t reflect the main patterns you’re evaluating. Therefore, watching for compensatory movement of the hip, pelvis, and lumbar spine best reflects what the FABER test is assessing.
