Postural Control Exam 3 Practice

Postural control has two broad purposes: keeping the body stable in the face of gravity and disturbances, and maintaining proper orientation of the body in space to meet the demands of the task. Stability means resisting shifts that could throw you off balance, keeping the head, trunk, and limbs aligned over the base of support so you don’t fall during standing, walking, or standing on uneven surfaces. Orientation involves using sensory information to keep your body segments aligned with the environment and the task—knowing where you are, how you’re facing, and how to position yourself for reaching, stepping, or adjusting to changes in the surroundings. These two aims—stability and orientation—together capture the core purpose of postural control. The other descriptions refer to different aspects of fitness or movement, like how strong or flexible you are, or how quickly you can move, but they don’t define the fundamental goals of postural control.
