Benign Positional Paroxysmal Vertigo (BPPV)

Welcome to PT 635 Pathophysiology of Complex Patient Problems This is a wiki created by and for the students in the School of Physical Therapy at Bellarmine University in Louisville KY. Please do not edit unless you are involved in this project, but please come back in the near future to check out new information!!


Benign Paroxysmal Positional Vertigo (BPPV) is the most common cause of vertigo, which is a symptom of the condition[1]. Though not fully understood, BPPV is thought to arise due to the displacement of otoconia (small crystals of calcium carbonate) from the maculae[1] of the inner ear into the fluid-filled semicircular canals. These semicircular canals are sensitive to gravity and changes in head position can be a trigger for BPPV[2]. The posterior canal is the most commonly affected site, but the superior and horizontal canals can be affected as well[3]. It should be noted that the superior canal is sometimes also referred to as the anterior canal and the horizontal canal is sometimes referred to as lateral canal.

The peripheral vestibular labyrinth contains sensory receptors in the form of ciliated hairs in the three semicircular canals and in the ear’s otolithic organs. They respond to movement and relay signals via the eighth cranial nerve. Visual perception such as gravity, position, and movements also receive signals from somatosensory receptors in the peripheral vestibules. With the displacement of the otoconia into the semicircular canals, these delicate feedback loops relay conflicting signals that can result in any symptom related to BPPV[4].

BPPV can be classified as cupulolithiasis and canalithiasis. Cupulolithiasis is when the otoconia are adhered to the cupula and canalithiasis is when the otoconia are free floating in the canal. Additionally, the type of nystagmus that a patient may display can be classified as geotropic or apogeotropic. Geotropic describes the nystagmus as a horizontal beat towards the ground. Apogeotropic describes the nystagmus as a horizontal beat towards the ceiling[5].


The most common cause of BPPV is idiopathic. However, the vestibular system of the inner ear can also undergo degenerative changes as one ages which can attribute to a potential cause of BPPV. Under age 50, head injury is a common cause. Vestibular viruses and Meniere’s disease also play a role. BPPV can also be a result of surgery due to prolonged supine positioning and possible trauma to the inner ear[6].

Risk factors include[2][7][8]:
• Female sex
• Hypertension (HTN)
• Hyperlipidemia
• Cerebrovascular disease
• Menopause
• Allergies
• Migraine
• Chronic Obstructive Pulmonary Disease (COPD)
• Surgical procedure such as a cochlear implant
• Infection


  • Dizziness is the complaint in 5.6 million clinical visits in the United States per year, and between 17 and 42 percent of these patients are diagnosed with BPPV[9].
  • Female to male ratio is 3:1[7]
  • The recurrence rate for individuals at one year following initial bout of BPPV is 15% and at 5 years the recurrence rate is 37-50%[10].
  • Individuals with a clinical diagnosis of anxiety are 2.7 times more likely to develop BPPV[7].
  • Unilateral posterior canal is the most commonly affected canal in BPPV with 90% of all BPPV diagnosis[11].
  • Unilateral horizontal canal affects 5-15% of all BPPV diagnosis. Within a horizontal canal diagnosis, 2/3 of the cases are geotropic while 1/3 of the cases are apogeotropic[11].
  • Anterior canal affects 1-2% of all BPPV diagnoses, which is the least common[11].
  • The lifetime prevalence is 2.4 percent[9].

Characteristics/Clinical Presentation

Symptoms of BPPV include:[12]

  • vertigo
  • light headedness
  • loss of balance
  • nausea
  • vomiting
  • nystagmus with positional change of the head

Symptoms are considered mild if the individual has inconsistent positional vertigo[10].

Symptoms are considered moderate if the individual has frequent positional vertigo attacks with disequilibrium between vertigo attacks[10].

Symptoms are considered severe if the individual has vertigo with most head movements, which can appear as continuous vertigo[10].

Individuals with BPPV can have symptoms that last days, weeks, months or years before it is resolved[10].

Each episode of vertigo or nystagmus lasts only seconds[13].

Associated Co-morbidities[2][5]

• Meniere's disease
• Vertebral basilar insufficiency
• Migraine
• Multiple sclerosis
• Infection: sinus or ear
• Thyroid problems
• Reduced bone mineral density
• Sudden hearing loss

Systemic Involvement 

Fortunately, BPPV has very little systemic involvement. In severe cases of vomiting caused by BPPV, one may be at risk of dehydration[12].

Individuals who have a diagnosis of BPPV are at a higher risk for falls, which could affect other systems such as, vascular, musculoskeletal, etc.[7].

Diagnostic Tests/Lab Tests/Lab Values

Dix-Hallpike test[9]
Dix-Hallpike Test

  1. To check for right side involvement, rotate the patient's head to the right 45 degrees while in the long sitting position (this aligns the right posterior semicircular canal with the sagittal plane of the body).
  2. The examiner grasp the patient's head and quickly moves the patient to the supine position with the neck slightly extended (ear down position).
  3. The examiner checks for nystagmus. If present, note the latency, duration, and direction (should not last more than 1 minute).

Head Pitch Test (“Bow and Lean” Test)[11]
This test is used to assess unilateral horizontal canal BPPV.

  1. Patient is seated.
  2. Examiner first bends the patient’s head forward 30 degrees. Reassess nystagmus. Patient’s nystagmus should disappear because the horizontal canal is now in a true horizontal position.
  3. Examiner then bends the patient’s head forward to 60 degrees. Reassess nystagmus. A fast paced nystagmus may be present. If the nystagmus is being caused by the otoconia moving, the nystagmus will beat toward the affected ear. If the otoconia is attached to the cupula, the nystagmus will beat towards the unaffected ear.
  4. Examiner bends the patient’s head backwards 30 degrees. Reassess nystagmus. May see an increase in nystagmus due to the horizontal canal being vertical.

Head down test[11]
Examiner moves patient from a seated position to a supine position quickly while head remains in the sagittal plane. Reassess nystagmus.

Horizontal Roll Test
This test is used to assess the horizontal semicircular canal. 

  1. Patient is supine. Examiner flexes the cervical spine 20-30 degrees. 
  2. Examiner quickly rotates the head to the right, approximately 45 degrees. Hold for 30 seconds or until nystagmus and/or other symptoms have subsided. 
  3. Slowly return patient's head to midline.
  4. Next, quickly rotate the patient's head to the left, approximately 45 degrees. Hold for 30 seconds or until nystagmus and/or other symptoms have subsided.
  5. Slowly return patient's head to midline.

Test is positive for nystagmus or other symptom complaints during the test. The patient may be positive on both sides, if this happens; the side that experiences more intesne symptoms is considered the affected side.  


Measures involuntary eye movements with the head placed in different positions or by stimulating the balance organs.

Magnetic resonance imaging (MRI)[12]

Uses a magnetic field and radio waves to create cross-sectional images of the body. Would most likely be used to rule out acoustic neuroma or other lesions.

Medical Management (current best evidence)

BPPV is a benign diagnosis so treatment is not always needed. Occasionally, BPPV can resolve itself with no intervention[14].

• Singular Nerve Neurectomy
• Posterior Canal Occlusion

• There are no medications that directly treat BPPV
• Antivert, Meclizine and vestibular suppressants can be prescribed to treat dizziness, nausea and other symptoms related to BPPV[15]

Drug treatments are not presently recommended for BPPV and bilateral vestibular paresis.

  • Prophylactic agents (L-channel calcium channel antagonists, tricyclic antidepressants, beta-blockers) are the mainstay of treatment for migraine-associated vertigo.
  • In individuals with stroke or other structural lesions of the brainstem or cerebellum, an eclectic approach incorporating trials of vestibular suppressants and physical therapy is recommended.
  • Psychogenic vertigo occurs in association with disorders such as panic disorder, anxiety disorder and agoraphobia. Benzodiazepines are the most useful agents here.
  • Undetermined and ill-defined causes of vertigo make up a large remainder of diagnoses. An empirical approach to these patients incorporating trials of medications of general utility, such as benzodiazepines, as well as trials of medication withdrawal when appropriate, physical therapy and psychiatric consultation is suggested[16].

Physical Therapy Management (current best evidence)

Canalith Repositioning Procedure

Canalith Repositioning Procedure (Epley’s)[9]

  1. Patient starts in long sitting with the head rotated 45 degrees to the affected side.
  2. Patient next rapidly reclined to the supine position with the neck slightly extended. This position is held for 30 seconds, or until nystagmus and dizziness subside.
  3. The patient's head is rotated 90 degrees to the opposite side. This position is held for 20 seconds, or until nystagmus and dizziness subside.
  4. The patient's head is turn another 90 degrees, requiring the patient to go from the supine to side-lying position. This position is held for 20 seconds, or until dizziness and nystagmus subside.
  5. The patient is brought up to the short-sitting position.

May need to complete this maneuver 1 to 3 visits complete resolution of symptoms.

Video resource for example:

Modified Epley’s Maneuver
Refer to video below for instructions:

Habituation techniques[6]

  1. Avoid quick spins or movements that provoke vertigo.
  2. Sleep in a semi-recumbent position for the next two nights following the above technique. In most cases a recliner works well, or stacking pillows at the head of the bed. Avoid sleeping on the affected side.
  3. Try to keep the head upright during the day, avoid all supine activities.
  4. After a week of being conservative, start to place the head (in controlled environments) in vertigo provoking positions.

Brandt-Daroff exercises[17]

  1. Begin by sitting upright on bed (position 1)
  2.  Lie down onto side. Take no more than 1-2 seconds to do this
  3. Keep head looking up at 45 degree angle. Imagine someone standing about six feet in front of you, and keep looking at the person's head at all times (position 2)
  4. Remain on this side for thirty seconds, or until dizziness subsides.
  5. Return to an upright position and wait for thirty seconds (position 3)
  6.  Now lie down onto the other side. Again, it should take one or two seconds to get into position
  7. Keep the head at a 45 degree angle (position 4)
  8. Stay down for another thirty seconds, or until vertigo subsides
  9. Return to an upright position and wait for another thirty seconds.
Semont maneuver[10]
Semont Manuever
  1. Patient begins sitting in the short sitting position. The head is rotated 45 degrees towards the unaffected ear.
  2. Examiner places one hand under the downmost shoulder while the other hand supports the neck
  3. The patient rapidly moves to side lying to the affected side (at this point to face should be oriented towards the ceiling). This position should be held for 30 seconds.
  4. Without any head movement, the patient is to move to side lying on the opposite side of the body (the face should be oriented towards the bed at this point). Hold this position for 30 seconds.

According to Bhattacharyya et al in a 2008 Otolaryngology-Head and Neck Surgery Journal, the Semont maneuver is more effective than Brandt-Daroff exercises. 

Lempert Maneuver[18]
Treatment for horizontal/lateral canal BPPV

  1. The patient should lie supine on the exam table, affected ear down
  2. Quickly turn the head 90° towards the unaffected side, facing up
  3. Wait 15-20 seconds between each head turn
  4. Turn the head 90° so affected ear is up
  5. Have patient tuck arms to chest, roll patient to a prone position with face down
  6. Have patient turn on side as you roll their head 90° (returning to original position, affected ear down)
  7. Position the patient so they are face up and bring to a sitting position

Gufoni Maneuver[14]
Treatment for horizontal/lateral canal BPPV (geotropic and apogeotropic)

  1. Patient is taken from sitting position to side lying position on unaffected or affected side. Hold here for 60 seconds.                             a. Geotropic nystagmus, lay on to unaffected

          b. Apogeotropic nystagmus, lay on to affected side

      2. Patient’s head is quickly turned towards the ground, 45-60 degrees. Hold in this position for 2 minutes.

      3. Patient then returns to sitting with the head maintained in the same position.

Case Study Example

• Patient is a 65-year-old female. She presents to your clinic with dizziness and occasional nausea.
• Medical history:
     o HTN, controlled by medication
     o Migraines
     o Allergic to grass
She has not recently seen her cardiologist and has never seen a neurologist.

Upon further questioning, you find out that there is no mechanism of injury and dizziness occurs when she gets in and out of bed and bends over to pick items up off the ground.
• Examination findings:
     o Cranial nerve exam: no significant findings
     o Dix-Hallpike: upbeat torsional nystagmus when head is turned to the left
• Diagnosis:
     o Left posterior canal BPPV
• Intervention:
     o Epley’s Maneuver
After 1st attempt when re-checking via Dix Hallpike, patient was still positive with nystagmus on a left head turn
Following 2nd attempt, patient was negative with Dix Hallpike
