Comprehensive Positional Management System

Volunteers are needed to assess the efficacy of BPPV treatment:
A common form of dizziness is called benign paroxysmal positional vertigo (BPPV) which is caused by particles breaking off from the otolith receptors in the inner ear and falling into the fluid that fills the semicircular canals. There are three semicircular canals located in the inner ear and they are used by the brain to detect head rotations and to maintain balance. When otolith particles are in the canals patients may experience a spinning sensation as a result of certain head movements.

The Comprehensive Positional Management (CPM) system is designed to determine which canal contains particles and then rotate the body accurately and precisely to move the particles out of the canal. Currently the rotation procedures are done by manually positioning the patient.

Participants: This study is currently recruiting study subjects with BPPV. Sixty patients with BPPV will be treated, half with the CPM system and half manually. Patients who do not receive relief from their symptoms will be offered treatment using the other technique.
