Quick answer: BPPV (benign paroxysmal positional vertigo) is the most common cause of vertigo, affecting 15–20% of adults yearly. OTs working in hospital settings can play a key role in identifying, assessing, and managing BPPV, especially when it impacts a patient’s ability to perform daily activities safely.
Vertigo walks into your ward more often than you might think. A patient refuses to roll over in bed. Another can’t sit up without grabbing the rails. Someone else reports dizziness every time they reach for something overhead. Sound familiar?
These scenarios could all point to BPPV, and as an OT, you’re often the first clinician to notice them. Understanding BPPV means you can act faster, collaborate more effectively, and help your patients regain function sooner.
Here’s what you need to know.

What Is BPPV, exactly?
BPPV stands for benign paroxysmal positional vertigo. It occurs when calcium carbonate crystals—called otoconia—break free from their normal position in the inner ear and drift into the semicircular canals.
The semicircular canals are three fluid-filled tubes that help your brain track head movement. When loose crystals float into these canals, they disrupt normal fluid movement and send faulty signals to the brain. The result? Brief but intense episodes of spinning.
Key facts worth knowing:
- BPPV affects 15–20% of adults per year
- It’s two to three times more common in women
- The posterior canal is involved in about 80% of cases
- 25% of patients won’t report vertigo at all, only significant balance impairment
That last point matters for OTs. If you’re seeing unexplained balance issues during ADL performance, BPPV could be the culprit.
How does BPPV intersect with occupational therapy?
BPPV doesn’t just cause dizziness; it disrupts function. Patients may struggle with:
- Bed mobility and supine-to-sit transfers
- Reaching overhead or bending forward
- Dressing, bathing, and grooming tasks
- Safe ambulation and fall prevention
In a hospital setting, these limitations directly affect your OT goals. A patient who’s dizzy every time they move will resist therapy, delay recovery, and face a higher fall risk.
There’s also a diagnostic overlap you can’t ignore. BPPV is common following:
- Head trauma or concussion (87% of these patients experience vertigo; 38% have BPPV)
- Falls (26% of fall-related vestibular dysfunction cases involve BPPV)
- Cerebellar CVA, viral illness, ear surgery, and ototoxicity
Your patients already carry these diagnoses. BPPV may be riding alongside them.
Recognizing the symptoms of BPPV
BPPV has a recognizable pattern. Watch for:
- Vertigo triggered by rolling in bed or moving from supine to sitting
- Episodes lasting less than one minute
- Nystagmus (involuntary eye movements) during positional changes
- Nausea or vomiting in acute phases
- Vague lightheadedness or a “floating” sensation in chronic cases
- Blurred vision during dizzy spells
Importantly, symptoms are minimal when the head is still. If dizziness is constant regardless of position, consider other causes like orthostatic hypotension or cervicogenic vertigo.
BPPV assessment in a hospital setting
The Dix-Hallpike Maneuver (Posterior Canal Testing)
This is the gold standard for testing posterior canal BPPV. Here’s a simplified overview:
- Rotate the patient’s head 45 degrees toward the suspected side
- Lay the patient back with 10–15 degrees of cervical extension
- Observe eye movements for approximately 30 seconds
- Return to upright and note any reversal of nystagmus
Positive result: Severe vertigo with upbeating, torsional nystagmus toward the rotated side.
- Nystagmus that fatigues in 5–10 seconds = canalithiasis
- Persistent nystagmus = cupulolithiasis (crystals stuck to the cupula membrane)
The Roll Test (Horizontal Canal Testing)
Used when horizontal canal involvement is suspected:
- Lay the patient supine with head in neutral
- Rotate head 45–90 degrees to each side
- Watch for horizontal beating nystagmus
Geotrophic beating (toward the ground) = canalithiasis. Ageotrophic beating (away from the ground) = cupulolithiasis. In both cases, the affected side produces the stronger response.
Testing tips for hospital settings
- No infrared goggles? Ask patients to keep their eyes open and avoid visual fixation on stationary objects
- Limited cervical ROM? Use pillows and extra staff to position safely. Head position matters more than neck position
- Vestibular-suppressant medications can reduce test accuracy; note them in your assessment
- Always explain the test beforehand to reduce patient anxiety
BPPV treatment: The main maneuvers
Treatment aims to guide loose crystals out of the semicircular canals using gravity and repositioning.
Epley Maneuver: Posterior Canalithiasis
The most effective treatment for the most common type of BPPV. It involves four sequential head positions, holding each until vertigo resolves, plus 30–45 seconds.
Liberatory Maneuver: Posterior Cupulolithiasis
Used when the Epley is unsuccessful or when crystals are adhered to the cupula. This maneuver uses quick repositioning and longer hold times (2 minutes per position).
BBQ Roll: Horizontal Canalithiasis
A five-step rotation from affected side, through neutral, to prone, and back again. Each position is held until vertigo stops plus 30–45 seconds.
Semont Maneuver (Modified by Casani): Horizontal Cupulolithiasis
Involves a rapid side-lying transition with head rotation toward the floor. Note: newly dislodged debris can migrate to the posterior canal after treatment, so reassess the following day.
Post-treatment care and patient education
After treatment, the vestibular system is highly sensitized. Here’s what to communicate:
- Patients should avoid vertigo-provoking positions after treatment
- Balance may temporarily worsen—this is expected
- In a hospital setting, avoid standing or walking for 2–3 hours post-treatment
- Symptoms may take 2–24 hours to settle; avoid repeat treatment the same day
- Up to one-third of patients experience recurrence within a year. Educate them on self-treatment options and when to seek care
Ongoing imbalance after BPPV resolution is common and may reflect vestibular deconditioning or reduced vestibulo-ocular reflex (VOR). This is where OT rehabilitation continues to play a vital role.
Your role is bigger than you think
BPPV assessment and treatment isn’t just a PT domain. OTs in hospital settings have both the clinical proximity and the functional lens to identify BPPV early, screen appropriately, and deliver treatment within their scope of practice, depending on their setting and training.
Patients who get faster BPPV treatment go home sooner, fall less, and participate more fully in rehabilitation. That’s an outcome every OT can get behind.

Frequently asked questions
Can occupational therapists assess and treat BPPV?
Yes, in many states and settings, OTs can perform BPPV assessments and canalith repositioning maneuvers within their scope of practice. Always confirm with your state licensure board and facility policies before proceeding independently.
How do I tell BPPV apart from other causes of dizziness in hospital patients?
BPPV is position-dependent: symptoms appear with head movement and resolve within a minute. Constant dizziness regardless of head position may suggest orthostatic hypotension. Nausea triggered by SCM palpation and neck pain history points toward cervicogenic vertigo. When in doubt, use the Dix-Hallpike and Roll Test to guide your clinical reasoning.
What equipment do I need to assess BPPV in a hospital?
You don’t need specialized equipment. A treatment table or hospital bed, a pillow for positioning, a watch or clock for timing, and a nearby basin (in case of nausea) are sufficient. Infrared video-ocular goggles improve accuracy but aren’t required.
What should I do if a patient vomits during testing?
Stop the test, ensure patient safety, and allow symptoms to settle. Reschedule testing once the patient is stabilized. Always have a basin nearby, especially during cupulolithiasis testing, which tends to produce more intense and prolonged symptoms.
How soon can I reassess BPPV after treatment?
In a hospital setting, wait at least 2–3 hours before reassessing. Research shows a 2-hour follow-up is equivalent to a 24-hour follow-up. Ideally, retest the following day or refer to outpatient vestibular rehabilitation for continuity of care.
