This test is performed on patients who complain of dizziness, unsteadiness (balance disorder), or gait problems. Well-known locations where dizziness and balance disorders can occur are the ears, eyes, and the muscles and tendons of the legs. For example, disease of the vestibular canal in the inner ear can cause severe dizziness and balance disorders. Examples of phenomena involving the eyes include the feeling of unsteadiness when looking down from the roof of a tall building, and the dizziness that gets worse when a dizzy person closes their eyes.
