Which description matches balance displacement?

Which description matches balance displacement?

• A. Moving the subject's center of gravity toward stability
• B. Forcing the subject to sit down
• C. Moving the subject's center of gravity beyond the point of stability of their feet
• D. Maintaining the subject's balance to prevent injury

Answer: (C)

Balance displacement is about shifting a person’s center of gravity outside the edge of their base of support to disrupt stability. When the center of gravity moves beyond the point where their feet can provide support, they can no longer stay upright without adjusting, so balance is lost and movement becomes easier to control. That’s why the description describing moving the subject’s center of gravity beyond the point of stability of their feet is the best match. The other ideas describe keeping or forcing stability (which would prevent or negate balance disruption) rather than causing it.
