Stage 3 protocol: which action is described?

• A. One foot is slowly lowered to tap the floor and returned to tabletop while pressure remains constant.
• B. Both legs are lowered together to the floor.
• C. One leg is raised to join the other.
• D. The pelvis is rotated.

Answer: (A)

In Stage 3, the emphasis is on controlled, single‑limb movements that maintain spinal stability. The action described—slowly lowering one foot from tabletop to tap the floor and then returning it—fits this goal precisely. It requires keeping the pelvis and spine stable (often by maintaining consistent abdominal pressure) while the leg moves through a small, controlled range. This trains the ability to control eccentric lowering with one leg without letting the lower back arch or the pelvis rotate. Lowering both legs at once would be more demanding and could destabilize the spine, making it less appropriate for Stage 3 progression. Raising a leg instead of lowering it doesn’t match the described action, and rotating the pelvis would indicate a loss of stabilization, not the controlled stability Stage 3 aims for.
