Testing the Epley Maneuver for Treating Dizziness in the Emergency Department: A Randomized Study

Not Applicable

Not yet recruiting

• Conditions: Benign Paroxysmal Positional Vertigo (BPPV)

• Registration Number: NCT07111000
• Lead Sponsor: American University of Beirut Medical Center

Brief Summary

The goal of this randomized controlled trial is to evaluate the efficacy of the Epley maneuver versus a sham maneuver in treating patients presenting to the emergency department (ED) with BPPV. The main questions that the study aims to answer are:

* What is the mean difference in Dizziness Handicap Inventory (DHI) scores between patients receiving the Epley maneuver and those receiving the sham maneuver 3 days after enrollment?

* What is the immediate response (using a 0-10-point Likert scale) of patients in each arm of the study?

* What is the proportion of patients who, despite agreeing to participate, were unable to complete the full Epley maneuver due to symptom severity?

Researchers will compare the Epley maneuver arm to the sham maneuver arm to see if the Epley maneuver is more effective in reducing BPPV symptoms.

Participants will:

* Undergo either the Epley maneuver or a sham maneuver.

* Complete the Dizziness Handicap Inventory (DHI) questionnaire at baseline and 3 days post-discharge.

* Patients with insufficient improvement in the sham maneuver group will receive a rescue Epley maneuver.

* Have their vertigo severity assessed using a 0-10 point Likert scale at baseline, immediately and post-maneuver.

Primary Outcome Measures

Name	Time	Method
Efficacy of Epley	3 days	The study will compare the average Dizziness Handicap Inventory score change from baseline to day 3 between the Epley maneuver group and the sham maneuver group.

Secondary Outcome Measures

Name	Time	Method
Immediate response of patients	15-30 minutes after intervention	The severity of vertigo will be evaluated using both a 0 to 10-point Likert scale before and after applying the Epley/Sham maneuver.
Rate of bounce-back to the ED	3 days	Calculate the proportion of patients in each arm of the study who return to the ED.
Proportion of patients unable to undergo the full Epley maneuver	15 minutes	The percentage of patients who agreed to participate but could not complete the Epley maneuver due to the severity of their symptoms.
