Primary Outcome Measures:
  • Treatment of Apogeotropic Horizontal Canal Benign Paroxysmal Positional Vertigo: A Randomized Clinical Trial [ Time Frame: one hour ]
    The immediate treatment response was determined by participating neurologists in each clinic without knowing the maneuver applied to each patient from 30 minutes to one hour after initial maneuver. The absence of both vertigo and nystagmus was required to determine a resolution.

Enrollment: 157
Study Start Date: January 2009
Study Completion Date: May 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Gufoni maneuver
Gufoni maneuver for apogeotropic HC-BPPV
Procedure: Gufoni maneuver
For Gufoni maneuver,16,18 the patient was quickly brought down to the side-lying position on the affected ear from the sitting position. After one minute in this position, the head of the patient was quickly turned 45O upward, so that the nose directed upward. Approximately 2 minutes later, the patient was returned to the upright position (Figure 2A).
Active Comparator: Headshaking maneuver
headshaking maneuver for apogeotropic HC BPPV
Procedure: Head-shaking maneuver
For head-shaking maneuver,15 patients were brought into a sitting position. After pitching the head forward by approximately 30O, we moved the head sideways in a sinusoidal fashion at an approximate rate of 3 Hz for 15 seconds.
Sham Comparator: sham maneuver
sham maneuver for apogeotropic HC BPPV
Procedure: sham maneuver
For the sham maneuver, patients quickly lied on the unaffected side, and returned to the sitting position after one minute.

Detailed Description:
A randomized prospective study of patients with HC-BPPV. Patients with apogeotropic type of HC-BPPV were randomized to one of each three treatment groups at their first clinic visit. These groups included the Gufoni maneuver, head-shaking maneuver, and sham group in apogeotropic HC-BPPV. Responsiveness of treatment maneuver was determined by positioning maneuver immediately after each treatment method based on resolves of vertigo and positional nystagmus.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • a history of brief episodes of positional vertigo,
  • direction-changing horizontal nystagmus beating toward the uppermost (apogeotropic nystagmus) or undermost (geotropic nystagmus) ear in both the lateral head turning positions,
  • no spontaneous nystagmus during upright sitting position, and
  • absence of identifiable central nervous system disorders that could explain the positional vertigo and nystagmus.

Exclusion Criteria:

  • central positional nystagmus with identifiable CNS lesions that could explain the positional nystagmus
