During Sahrmann test stage 2, from tabletop position, what movement occurs?

• A. From tabletop position, the opposite leg is lifted to join the first while maintaining constant pressure and neutral spine.
• B. From crook lying, the same leg is lifted first while increasing pressure.
• C. From standing, the trunk is rotated while maintaining pressure.
• D. From prone, the leg is extended while releasing pressure.

Answer: (A)

In this stage of the Sahrmann progression, the focus is on maintaining spinal stability while adding a challenge with limb movement. Starting from a tabletop position, you keep the spine in a neutral alignment and hold a constant abdominal or spinal pressure (a steady brace) so the lower back doesn’t sag or arch. Then you lift the opposite leg to join the first leg, continuing to hold that neutral spine and constant pressure as you bring the legs together. This pattern tests how well the deep stabilizing muscles of the core—like the transversus abdominis and multifidus—and the pelvis can coordinate as both legs move, without letting the trunk move. The other options don’t fit this stage because they involve different starting positions, different movements, or releasing the stability that’s being tested. Lifting the same leg from a crook-lying start changes the load and doesn’t require meeting the other leg while preserving neutral spine. Standing with trunk rotation introduces a different plane of motion and load, not a controlled back-stabilizing task from tabletop. Extending the leg from prone while releasing pressure also shifts the movement away from maintaining a stable, neutral spine with coordinated limb advancement.
