Effects of Physical Treatment on Postural Stability in Benign Paroxysmal Positional Vertigo (BPPV) Patients

Study Overview
=================
Brief Summary
-----------------
The propose of this study is to compare two methods of physical treatment for benign paroxysmal positional vertigo, by evaluating treatment effects on postural stability. The trail design is a double blinded randomized controlled trail, with each patient going through three evaluations: before treatment, 1 week after treatment and 60 days after treatment.

Eligibility Criteria
-----------------
Inclusion Criteria: medical referral for treating vertigo subject has short episodes of rotatory vertigo (up to 1 minute) subject has positive Hallpike-Dix test with typical nystagmus repeated Hallpike-dix test will show fatigability Exclusion Criteria: Hallpike-Dix test produces vertigo without nystagmus subject has BPPV of the horizontal or anterior semi-circular canal subject has other known vestibular or neurologic condition subject has nystagmus of a different type subject has a cervical spine problem which prevents the utilization of Epley or Semont maneuvers subject is unable to stand for 1 minute subject gets pharmacologic treatment for vertigo while doing the postural stability evaluation subject is under 18 years old or a pregnant female or cannot obtain informed concent
