The Epley maneuver is used to reposition BPPV crystals.

It is the first procedure of its kind to help with vertigo. Published in the early 90’s by the late US-based physician named, John Epley, since then, many healthcare providers and vertigo researchers around the world have developed a whole catalog of additional “particle repositioning maneuvers.”

In this blog, I discuss the top five reasons why the Epley maneuver may not be effective for vertigo treatment.


First of all, many providers who are “dabbling” in vertigo care perform the maneuver incorrectly.

The Epley maneuver, the modified Epley, and all the particle repositioning maneuvers for BPPV require very precise, technically accurate performance to be effective. Unless the provider has studied the technique to reproduce precision and accuracy, they may be performing the Epley maneuver incorrectly.

In teaching this maneuver and other particle repositioning treatments to other providers, I have discovered certain predictable errors that are made by beginners. Those errors will reduce the effectiveness of the treatment.


It is important to treat the correct ear in order for the Epley maneuver to work. The first step to effectively treating BPPV is to determine which ear is involved.

The options are right ear, left ear, or both ears. This can be determined through BPPV testing by a skilled provider.


There are three semi-circular canals in each inner ear. You must determine the canal that needs treatment.

The Epley maneuver is designed for the long arm of the posterior canal. If BPPV crystals are free-floating in the horizontal, anterior canal, or short arm of the posterior canal then the Epley maneuver will not likely resolve the complaint.

Those other inner ear canals require different treatments that have been developed after the Epley maneuver was first published.


BPPV particles can get stuck. The Epley maneuver makes an assumption that the BPPV crystals are free-floating in the long arm of the posterior canal of the ear being treated. However, there is a possibility that the BPPV crystals or debris can adhere to the sensory apparatus within the semi-circular inner ear canal called the “cupula.”

This is a type of BPPV called “cupulolithiasis,” as opposed to the more common “canalithiasis” with free-floating crystals.

Cupulolithiasis is rare. In my experience treating literally thousands of people with BPPV, I have only found a small percentage of people so far who have BPPV crystals stuck on their cupula.

It is possible to break the BPPV crystals off the cupula and resolve the problem, but starting with the Epley maneuver will not be effective in this case.

Why Doesn’t the Epley Maneuver Work?

Another reason why the Epley maneuver may not work is that you may not be dealing with BPPV.

There are other conditions that can mimic BPPV, even causing positional nystagmus and positional vertigo symptoms.
