Postural stability is defined as:

• A. The ability to maintain your body's position and balance while moving or standing still
• B. The ability to perform rapid limb movements
• C. The ability to improve cardio endurance
• D. The ability to adjust breathing during movement

Answer: (A)

Postural stability is the ability to keep the body aligned and balanced relative to its base of support, whether you’re standing still or moving, and to do so in the face of perturbations from the environment. In hippotherapy, this means maintaining proper trunk and limb control so the rider can stay upright and steady while the horse moves, allowing safe and effective engagement in therapeutic activities. The other options describe different motor or physiological skills—rapid limb movements, cardiovascular endurance, and breathing control—not the inherent ability to hold and adjust the body’s position against forces and movement.
