<p>A method and apparatus are disclosed for visually guiding a person's head into a position sequence necessary to allow abnormally positioned crystals to fall out of a posterior membranous semicircular canal to relieve the symptoms of benign paroxysmal positional vertigo. The apparatus includes a fluid suspended, buoyancy neutral inner member (305), which has printed upon it a sequentially numbered series of position bull's eyes, which are connected by a path printed on the inner member (305). The inner member (305) is contained within a transparent, watertight outer housing (302), which has a sighting marking (306) printed upon it. The device is attached to the user's head in a manner such that the outer housing sighting marking (306) and an aligned inner member (305) position bull's eyes can be seen by the user. The inner member (305) has a magnet (390) which keeps it aligned with a magnetic field with the outer housing (302) being movable about the inner member (305).</p> |
