Abstract: The apparatus includes a fluid suspended, inner member, which has printed upon it a series of position bull's eyes, which are connected by a path printed on the inner member. The inner member is contained within a transparent, watertight outer housing, which has a sighting marking printed upon it. The device is attached to the user's head in a manner such that when the user moves his head, the outer member can move relative to the inner member. This allows the user to follow the path to visually track his correct head position through the posterior canalith repositioning maneuver sequence. Also attached to the user apparatus is an assistant apparatus which includes a hollow ball containing a liquid sufficient to form a small bubble which allows an assistant to follow a second path which corresponds to that seen by the user when he follows the user path.

Abstract: A computational statistical determination is made as to whether a person suffers from benign paroxysmal positional vertigo (BPPV) based upon answers provided by a person to questions stored in a computer. The person answers questions about the characteristics of his or her vertigo, dizziness or imbalance symptoms. Based on proprietary information about the predictive value of each question, and the relationships between the questions, the person is given a statement of the chance of his or her having BPPV which would be responsive to a head maneuver designed to clear gravity sensitive crystals from a sensitive semicircular canal (SCC) area to a less sensitive area of the inner ear. Based on this determination, the person 1) is offered for sale an apparatus for further diagnosis and an apparatus to relieve his BPPV symptoms by self-treatment or 2) he may be told to go to a healthcare provider for treatment.

Abstract: 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, 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. The inner member is contained within a transparent, watertight outer housing, which has a sighting marking printed upon it. The device is attached to the user's head in a manner such that the outer housing sighting marking and an aligned inner member position bull's eyes can be seen by the user. The inner member has a magnet which keeps it aligned with a magnetic field with the outer housing being movable about the inner member.

Abstract: In one embodiment, the apparatus has two planar anterior surfaces, and two posterior planar surfaces located such that the two anterior surfaces are at the front of the apparatus and the two posterior surfaces are at the rear of the apparatus. Opposite anterior and posterior surfaces flare outward and downward relative to each other at angles of about 20 degrees. As seen from an upper plan view of the apparatus, adjacent surfaces form an angle of 90 degrees. A cavity is formed in the apparatus from the lower end for receiving a person's head with the anterior surfaces being located at the front of the person's head and the posterior surfaces being located at the rear of the person's head.
