Which is a fixed support strategy?

• A. Ankle strategy
• B. Stepping strategy
• C. Change in support
• D. Hip strategy

Answer: (D)

The main idea is balancing with a fixed base of support. A fixed-support strategy keeps the feet planted on the ground while the body corrects sway. The hip strategy does exactly this: it uses hip flexion and extension to move the trunk and adjust the body's center of mass back over the feet without stepping. This keeps the base of support constant, distinguishing it from strategies that change the base, like stepping or grabbing/support changes. While ankle corrections also keep the feet in place, the hip strategy is the classic example of a fixed-support response, especially when larger or more proximal adjustments are needed to restore balance.
