Which are two common sacral somatic dysfunction patterns?

• A. Nutation and counternutation; sacral torsions (right-on-right or left-on-left).
• B. Nutation only
• C. Counternutation only
• D. Nutation and torsions on the same side

Answer: (A)

Sacral somatic dysfunction is commonly seen in two broad patterns: sagittal plane motions (nutation and counternutation) and torsions along oblique axes (right-on-right or left-on-left). The best choice reflects both directions of the sacral base motion and the classic torsion patterns: nutation and counternutation together with sacral torsions on the right-on-right or left-on-left axes. If you only have nutation or only counternutation, you’re missing the other direction of flexion/extension. If you mix in torsions but say they’re on the same side without acknowledging the opposite torsion pattern, you’re not capturing the common two-pattern presentation.
