Anticipatory postural control involves what?

• A. Maintaining posture before a known disturbance
• B. Choosing to partake in destabilizing action
• C. Responding after a perturbation
• D. Constant posture in all tasks

Answer: (B)

Anticipatory postural control is about pre-emptive adjustments the body makes before a movement or expected disturbance to keep balance. It uses feedforward planning to shift the center of mass and tune muscle activity in advance, so stability is maintained when the destabilizing force is applied.

This is best described by maintaining posture before a known disturbance—you're preparing ahead of time because you anticipate what will challenge your balance. The other ideas describe reacting after something happens, choosing to destabilize yourself, or holding a single rigid posture across tasks, none of which capture the predictive, preparatory nature of anticipatory adjustments.
