The Dix-Hallpike test is a diagnostic manoeuvre used to identify benign paroxysmal positional vertigo (BPPV).

The Epley manoeuvre is used to treat BPPV (usually of the posterior canal) once it has been diagnosed by the previously mentioned Dix-Hallpike test.

This article provides a step-by-step guide to performing both the Dix-Hallpike test and the Epley manoeuvre in an OSCE setting.

Indications for the Dix-Hallpike test

The Dix-Hallpike manoeuvre is indicated for patients with paroxysmal vertigo in whom BPPV is considered in the differential diagnosis. These patients experience vertigo in brief episodes lasting less than one minute with changes of head position and return to normal between episodes. Light-headedness or a sensation of nausea might last longer than one minute, however, if the sensation of movement persists for more than one-minute alternative diagnoses should be considered. ¹


Wash your hands and don PPE if appropriate.

Introduce yourself to the patient including your name and role.

Confirm the patient’s name and date of birth.

Briefly explain what the examination will involve using patient-friendly language: “Today I need to perform some assessments to help diagnose and possibly treat the dizzy episodes you’ve been experiencing. The first stage will involve moving you from a sitting to lying position briskly on the examination couch. The second stage will involve me holding your head whilst asking you to roll onto your side and then to sit upright.”

Check if the patient has any back or neck problems that would contraindicate performing the assessments:

  • “Do you have any neck or back problems?”
  • “Do you have any pain anywhere currently?”

Check the patient has someone who can help them get home safely, as they may be dizzy after the procedure.

Gain consent to proceed with the examination.

Ask the patient to sit on the examination couch.


It’s important to have an awareness of absolute and relative contraindications to performing the Dix-Hallpike and Epley maneuvres. ²

Absolute contraindications:

  • Fractured odontoid peg
  • Recent cervical spine fracture
  • Atlanto-axial subluxation
  • Cervical disc prolapse
  • Vertebrobasilar insufficiency
  • Recent neck trauma

Relative contraindications:

  • Carotid sinus syncope
  • Severe neck or back pain
  • Recent stroke
  • Cardiac bypass surgery within the last 3 months
  • Rheumatoid arthritis affecting the neck
  • Recent neck surgery
  • Cervical myelopathy
  • Severe orthopnea

Dix-Hallpike test

When performing the Dix-Hallpike test, make sure to warn the patient in advance of each step, so that they know what to expect:

1. Ask the patient to sit upright on the examination couch.

2. Adjust the patient’s position so that when supine, their head will hang over the edge of the bed, allowing for head extension below the horizontal plane.

3. Position yourself standing behind the patient.

4. Turn the patient’s head 45º to one side.

5. Whilst supporting the neck, move the patient from their sitting position to a supine position in one brisk smooth motion, ensuring their head hangs over the bed 30º below the horizontal plane. Ask the patient to keep their eyes open throughout this process.

6. Inspect the patient’s eyes carefully for evidence of nystagmus for at least 30 seconds.

7. If no nystagmus is observed, the test is then complete for that side and you should carefully help the patient sit back up.

8. After a short break, the test should be repeated on the other side, turning the patient’s head in the opposite direction during step 4.

Positive test

If the test is positive, the patient will complain of vertigo and you should be able to directly observe nystagmus.

Be aware that patients often feel very dizzy and nauseated when vertigo is triggered.

Asking the patient to fix their gaze once you’ve established nystagmus will often reduce their symptoms.


You should note the following characteristics of the nystagmus:

  • Duration
  • Direction
  • Latency

The typical findings in BPPV include:

  • A 2-20 second latent period followed by the onset of torsional (rotary) or horizontal nystagmus. Rotary nystagmus is the most common type and suggests the involvement of the superior semicircular canal. Horizontal nystagmus suggests the involvement of the lateral semicircular canal.
  • Nystagmus typically lasts between 20-40 seconds.
  • The nystagmus typically wanes with repeated Dix-Hallpike tests.
  • Differentiating different types of nystagmus can be clinically challenging. Often patients are referred to an audiologist for further assessment, where special cameras are used to differentiate nystagmus subtypes.

Epley manoeuvre

When performing the Epley manoeuvre, each position should be maintained until full resolution of symptoms and nystagmus has been achieved for at least 30 seconds:

1. The Epley manoeuvre typically follows on from a positive Dix-Hallpike test, so we will assume the patient is still positioned lying flat, with the head hanging over the end of the bed, turned 45º away from the midline.

2. Turn the patient’s head 90º to the contralateral side, approximately 45º past the midline, still maintaining neck extension over the bed. Keep the patient in this position for 30 seconds.

3. Whilst maintaining the position of the patient’s head, ask the patient to roll onto their shoulder (on the side their head is currently turned towards).

4. Once the patient is on their side, rotate the patient’s head so that they are looking directly towards the floor. Maintain this position for 30 seconds to a minute.

5. Sit the patient up sideways, whilst maintaining head rotation.

6. Once the patient is sitting upright, the head can be re-aligned to the midline and the neck can be flexed so that the patient is facing downwards (chin to chest). Maintain this position for 30 seconds.

The entire procedure can be repeated 2-3 times if needed, however, this will depend on whether the patient is able to tolerate further manoeuvres (as they often precipitate vertigo).

To complete the examination…

Explain to the patient that the examination is now finished.

Thank the patient for their time.

Dispose of PPE appropriately and wash your hands.

Summarise your findings.

Example summary

“Today I examined Mr Smith, a 25-year-old male. On general inspection, the patient appeared comfortable at rest and there were no abnormalities noted on inspection.”

“The Dix-Hallpike test on the left elicited vertigo and torsional nystagmus was observed. As a result, I performed the Epley manoeuvre, which resulted in the resolution of symptoms on the first attempt.”

“In summary, these findings are consistent with a diagnosis of BPPV.”

“For completeness, I would like to perform the following further assessments and investigations.”
