A seated flexion test is negative; the sacral bases are both deep; the ILAs are both deep. What is the diagnosis?

• A. Bilateral extension
• B. Anterior torsion
• C. Bilateral flexion
• D. No dysfunction

Answer: (D)

The main idea here is recognizing a balanced sacroiliac/sacral pattern. A negative seated flexion test on both sides means there’s no unilateral SI joint dysfunction. When the sacral landmarks are symmetrical—sacral bases with equal depth on both sides and ILA depth also equal—the sacrum is functioning in a neutral, balanced position with no torsion, flexion, or extension abnormality. Put together, these findings point to no somatic dysfunction of the sacrum.
