This system affects aspects of physical function like posture, balance, movement, coordination, attention, arousal level, impulsivity and behavior. The vestibular system works with all of our other systems to give us our perception of space, body position and orientation of the environment around us. Children affected by poor vestibular processing may be perceived as inattentive, lazy, overly anxious, or seeking attention. They may have trouble functioning at school, going out into the community and performing every daily tasks.
