Which test uses hip flexion to assess sacroiliac joint motion?

• A. Navicular drop test
• B. Windlass test
• C. Standing Flexion Test
• D. Stork test

Answer: (D)

The Stork test uses hip flexion to load the sacroiliac joints. In this test, the patient stands on one leg and lifts the opposite knee, bringing the hip into flexion and causing pelvic tilt that stresses the SI joints. If this motion reproduces pain or reveals abnormal movement, it suggests sacroiliac joint dysfunction or restricted motion. The other tests don’t rely on hip flexion to assess the SI joint: navicular drop looks at arch height in the foot, the Windlass test tensions the plantar fascia by toe extension, and the Standing Flexion Test evaluates SI joint motion during trunk flexion without significant hip flexion.
