Limits of Stability describe what?

• A. Base of Support
• B. Limits of Stability
• C. Center of Mass
• D. Center of Gravity

Answer: (B)

Limits of Stability describes how far you can deliberately shift your center of mass in any direction while staying within your base of support without losing balance or taking a step. It defines the boundary of stable sway: as long as the center of mass remains inside the base of support, you can recover from small perturbations using ankle or hip strategies. If the center of mass reaches the edge, balance becomes unstable and a step or support is typically required. The base of support provides the physical area, while the center of mass is the point where your body’s mass acts; center of gravity is a related concept, but LOS specifically refers to the maximum CoM displacement within the base of support.
