The purpose of this study was to determine the relative short- and long-term efficacy of
several physical treatment paradigms commonly employed for the treatment of benign
paroxysmal positional vertigo (BPPV), including the canalith repositioning (Epley) maneuver,
the liberatory (Semont) maneuver, the Brandt-Daroff exercises and nonspecific vestibular
habituation exercises. These procedures involve exercises and head manipulations. Vertigo
intensity and frequency, the presence/absence of slow-phase eye movements, the degree of
dizziness handicap and acts of daily living (ADL) were assessed. The study also ascertained
the effects of co-morbid conditions on the response to treatment. While BPPV is a common
and significant public health problem that has been recognized for several decades, this is
the first systematic study of the relative treatment efficacy of different physical
treatment modalities for this disorder.
Patients may be eligible for this study if they:
- Are at least 21 years old.
- Have a diagnosis of unilateral posterior semicircular canal BPPV according to
established clinical test criteria.
- Have functional to normal range of motion of the neck and the back.
Patients will not be eligible for this study if they:
- Have a history of prior ear surgery or prior treatment for BPPV.
- Have an orthopedic or connective tissue disorder that impairs functional neck or
trunk range of motion.
- Have a significant neurological disorder or spinal cord damage.
- Are on vestibular suppressant medications.
- Have Meniere's disease or acoustic neuromas.
