Which category does stepping strategy belong to?

Explanation:
Stepping to regain balance is changing the base of support. When a perturbation pushes you beyond the limits of the current stance, taking a step creates a larger support polygon and lets you reposition your center of mass over the new base, restoring stability. That action falls under change in support, because you alter the ground contact points rather than keeping the feet fixed and relying only on ankle or hip adjustments. The other ideas describe different concepts: fixed support keeps the base unchanged, synergy refers to how muscles activate together, and feedback control is about using sensory input to adjust movements, not the category of balance strategy.
