January 6, 2014 updated by: Hong Ju Park, Asan Medical Center
The Effectiveness Comparison of Three Different Methods for the Treatment of Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: Prospective, Double Blinded, Randomized, Multicenter Clinical Trial
The purpose of this study was to compare the treatment effectiveness of three different methods for posterior semicircular canal benign paroxysmal positional vertigo.
The included methods are Modified Epley maneuver, Semont maneuver and Sham maneuver.

Detailed Description
This study was a prospective, double blinded, randomized, multicenter clinical trial.
The enrolled posterior semicircular canal benign paroxysmal positional vertigo patients were randomized to one of the three treatment regimens when they are diagnosed with the Dix-Hallpike test.
An then the patient was treated with one of the three maneuvers.
After 20 minutes, the patient was examined with the Dix-Hallpike test again.
The resolution of nystagmus and symptoms were checked.
When the nystagmus was sustained, the same treatment was applied once again.
And after 20 minutes, the patient was examined with the Dix-Hallpike test too. 1 day after and 7 days after, the patient was re-examined with the Dix-Hallpike test.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Epley maneuver
The group using modified Epley maneuver for PSCC BPPV
|
For Modified Epley maneuver, the patient was placed in the upright position with the head turned 45 degrees toward the affected ear.
And then the patient was rapidly laid back to the supine head-hanging position for 1 minute.
Next, the head was turned 90 degrees toward the other (unaffected) side for 1 minute.
Next, the head is turned a further 90 degrees (usually necessitating the patient's body to also move from the supine position to the lateral decubitus position) such that the patient' head is nearly in the facedown position for 1 minute.
The patient is then brought into the upright sitting position for 1 minute, completing the maneuver.
|
Active Comparator: Semont maneuver
The group using Semont maneuver for PSCC BPPV
|
Patient's head was turned 45 degrees toward the healthy side.
And then patient was rapidly moved to affected side-lying position and sustained for 2 minutes.
Next, Patient is rapidly taken to the opposite side-lying position without pausing in the sitting position or changing the head position relative to the shoulder for 2 minutes.
Next, Patient returns slowly with the head still tilted and fixed until the seated position for 1 minute.
|
Sham Comparator: Sham
The group using Reverse Epley maneuver for PSCC BPPV
|
Like the modified Epley maneuver, but the direction was reverse.

Measure Description |
Time Frame |
---|---|---|
Initial Effectiveness of Treatment for the Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo
Time Frame: 20 minutes
|
The immediate effectiveness of treatment was determined by otolaryngologists with the Dix-Hallpike test 20 minutes after initial manerver applied.
The investigator had no information of the treatment applied to the patient.
The complete resolution means absence of nystagmus and paroxysmal vertigo symptom.
If there was a sustained nystagmus, the latency and duration was measured.

Time Frame |
---|---|---|
Delayed Effectiveness of Treatment for the Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo
Time Frame: 1, 7 day
|
Ather 1 day and 7 days after the initial treatment was applied, the patients were re-visit the clinic and re-examined with the Dix-Hallpike test.
The absence of nystagmus and vertigo was determinded.
