Western University of Health Sciences is seeking men and women to participate in a study on the effectiveness of Osteopathic Manipulative Treatment (OMT) and Vestibular Rehabilitation Therapy (VRT) in patients with vertigo. The purpose of this study is to examine the efficacy of OMT in the treatment of individuals with vertigo, alone and in combination with Vestibular Rehabilitation Therapy (VRT). Because of the health care costs associated with vertigo, the cost effectiveness of OMT and VRT will also be examined.
