Continuing Education Activity

Patients with benign paroxysmal positional vertigo often present with recurrent symptoms of dizziness, lightheadedness, nausea, or vomiting. The following article describes the use of the Epley maneuver (or canalith repositioning maneuver) to treat benign paroxysmal positional vertigo (BPPV). This activity outlines the role of the interprofessional team in evaluating and treating BPPV with a low-cost, bedside solution.


  • Describe the pathophysiology of benign paroxysmal positional vertigo and the treatment with the Epley maneuver.
  • Outline the typical presentation of patients with benign paroxysmal positional vertigo needing Epley maneuver.
  • Review the process to properly perform the Epley maneuver.
  • Discuss interprofessional team strategies for improving care coordination and communication to advance the proper diagnosis and treatment of benign paroxysmal positional vertigo.


Whether one is a seasoned clinician or a medical student, dizziness can be difficult to diagnose and treat. It affects people of all age ranges with varying degrees of symptoms and severity. Additionally, dizziness can be difficult for patients to describe, as it can mean different things to different people. When a patient complains of “dizziness,” they could be describing vertigo, pre-syncope, balance issues, or giddiness. This difficulty in communication can result in frustration for both the patient and the provider; however, differentiating these symptoms is critical for the provider to treat the patient effectively. One critical step for providers is to characterize dizziness as “central vs. peripheral.” Dizziness can account for approximately 5% of walk-in clinics and roughly 4% of emergency department visits.[1] 

The differential diagnosis for dizziness encompasses numerous body systems, such as neurological, cardiovascular, or hematologic. Some studies have shown up to 15% of cases of dizziness in the emergency department are life-threatening.[1] Therefore, it is important to perform a thorough history, and physical exam as the ultimate diagnosis can be benign or life-threatening.

Symptoms and disease definitions are essential for professional communication between providers, whether they treat patients in the clinic, emergency department, or inpatient setting. The language utilized to describe terms such as ”dizziness” or ”vertigo” can often mean many different things based on one’s interpretations. Therefore, a committee was formed to promote the classification of vestibular disorders. Below are several definitions from the Committee for Classification of Vestibular Disorders to clarify these symptoms:

  • Vertigo: A sensation of self-motion when in reality, there is no motion occurring or a perceived sense of motion during a normal head movement.[2]
  • Dizziness: A sensation of an impaired or distorted sense of motion relative to spatial orientation.[2]

The canalith repositioning maneuver (CRP) was coined by Dr. John Epley in response to the need for non-invasive treatment for benign paroxysmal positional vertigo (BPPV).[3] Prior to the use of CRP, BPPV was often treated surgically. Following the diagnosis of BPPV, the Dix-Hallpike maneuver can localize the otolith. This manuscript will not detail how to perform the Dix-Hallpike maneuver; however, once the otolith is localized, the next step is to perform the CRP (Epley) maneuver. Of note, the endpoint of the Dix-Hallpike maneuver is the beginning of the Epley maneuver; thus, it is imperative to know how to perform both to be effective in diagnosing and treating BPPV correctly.

Anatomy and Physiology

BPPV is among the most common inner ear disorders that cause dizziness or vertigo.[4] The disease process appears to be caused by otoliths that become displaced in the semicircular canal.[5] The majority of these otoliths can be found in the posterior semicircular canal, followed by horizontal (lateral).[5]

These otoliths move due to gravity as the head is turning and cause inappropriate signaling that the head is moving when, in reality, it is not. When the vestibular apparatus, semicircular canals, and visual system are in disequilibrium, it elicits the sensation of dizziness. The classic symptoms of BPPV often involve brief episodes of rotational vertigo that are reproducible.[6]

The most common cause of BPPV is primary or ”idiopathic” as BPPV itself is often found in isolation. However, other inner ear pathologies such as Meniere disease and even migraines have links to BPPV.[7][8] Other common causes include head trauma and inner ear surgeries, which can often dislodge otoliths into the semicircular canals.


History and physical exams are pertinent in diagnosing BPPV correctly. The classic symptoms of BPPV often include sudden onset vertigo, worsened by head movements. These attacks can last for under one minute. However, patients have described them as lasting much longer due to associated nausea and disequilibrium.

When the clinician has diagnosed BPPV, the clinician has likely ruled out more dangerous etiologies of dizziness; it is crucial to communicate with the patient to assuage their fears because many patients present concerned about the more dire causes of dizziness, such as an intracranial mass or a stroke. Following a thorough history and physical exam, and the dizziness determined to be secondary to a peripheral cause, the Dix-Hallpike maneuver can be an option. If the etiology of the dizziness is unknown or if a central lesion is a consideration, other physical exam maneuvers such as the HiNTS exam should be employed to further aid in narrowing the differential diagnosis.


There are relatively few contraindications to the Dix-Hallpike maneuver; however, providers need to consider the patient’s physical anatomy and neck mobility concerning their ability to tolerate the quick actions and movements required to perform the maneuver. Patients with cervical spinal stenosis or limited cervical mobility may not tolerate the procedure well due to the quick cervical spine rotation and hyperextension needed for success.[9]

In a small study of 50 emergency physicians, barriers that contributed to decreased use of either the Dix-Hallpike maneuver or Epley maneuver included negative experiences associated with performing it, forgetting how to perform the maneuver, or relying on a history of present illness to diagnose BPPV. Overall, these physicians still had positive experiences with utilizing the Dix-Hallpike or Epley maneuvers.[10]


The absolute equipment required includes:

  • Examination table

Optional equipment and materials include:

  • IV access equipment
  • Premedication with antiemetics such as ondansetron, promethazine, or meclizine
  • Emesis bag
  • Pillow positioned under the shoulders for hyperextension of the neck

Using antiemetics before the Epley maneuver can provide comfort and temporary relief of nausea and emesis associated with the maneuver.


The Epley Maneuver is performable with one operator. Nursing staff can also be available at the bedside should the operator need assistance with moving the patient.


Utilize the Dix-Hallpike maneuver prior to performing the Epley Maneuver as it will allow for localization of the canalith. The following scenario will assume otolith localization to the right inner ear; simply reverse the directions if the otolith is on the contralateral side. A pillow may be placed on the bed and used to allow for the extension of the head past the horizontal.

Positioning: The patient is seated on the exam table, upright. The operator is standing behind the patient, near the head of the bed.


The examiner rotates the patient’s head 45 degrees to the right and quickly lays the head back over the end table. The patient’s eyes should exhibit torsional nystagmus. Each position should be held for at least 30 seconds. As the nystagmus improves, the otolith is descending and in an optimal position for the next step.

Rotate the patient’s head 90 degrees to the left, again holding for at least 30 seconds.

Instruct the patient to turn their entire head and body in the left lateral position, with the head facing 135 degrees from supine or 225 degrees from the starting position (looking at the floor).

Assist the patient in returning back to the sitting supine position while holding their head in place. The head position should be maintained as they are assisted in the sitting position, and repeat if necessary.


Some complications of using the technique include the inability to tolerate the quick movements needed to perform the maneuver successfully. Neck mobility requires an assessment before the maneuver. The operator should anticipate nausea and emesis; thus, premedication with an antiemetic such as ondansetron or promethazine is optional. In a Cochrane review, nausea was the most commonly cited symptom, which may cause intolerance to the procedure.[11]

Clinical Significance

The Epley maneuver is a low-cost, safe, and relatively benign treatment option for benign paroxysmal positional vertigo. It requires few resources and is a simple bedside solution to BPPV, whether in the clinic or emergency department. In a Cochrane review that compared the Epley maneuver to a control or sham maneuver, the Epley had a significant likelihood of symptom resolution (OR 4.4%, NNT=3).[11]

Enhancing Healthcare Team Outcomes

The interprofessional team is vital to the treatment of BPPV while using the Epley maneuver. Though the procedure only requires one operator, the situation may require anticipation of adverse side effects to produce satisfactory care. The physician, physician assistant, or nurse practitioner performing the procedure should anticipate nausea and vomiting; thus, communication with the nursing staff is vital to ensure the patient is either premedicated with an antiemetic or have these medications readily drawn in the event the patient requires it.

Nursing, Allied Health, and Interprofessional Team Monitoring

The nursing team should continue to monitor for nausea and vomiting during and after the procedure.
