BPPV stands for Benign Paroxysmal Positional Vertigo, and it’s the most common cause of sudden vertigo our team sees, particularly in people over 50.
Breaking down the name explains the condition itself:
- Benign means it isn’t dangerous
- Paroxysmal means it’s intermittent and comes on suddenly
- Positional means it’s triggered by certain head movements
- Vertigo describes the sensation of the room or world spinning around you
The good news is that BPPV is one of the more straightforward vertigo conditions to assess and diagnose. Once a physiotherapist has correctly identified what’s going on, complete resolution is typically expected within one to three treatment sessions.
What Causes BPPV?
BPPV is often described by patients as crystals in the ear, and some say their doctor told them they have rocks in the head. Both descriptions are getting at the same thing. Inside the inner ear sit tiny calcium carbonate crystals, which are a normal part of your balance system.
These crystals sit on two organs that give your brain information about your head’s position against gravity, whether you’re moving up and down or side to side, similar to the sensation of being in a lift or on a train.
With head trauma, or simply as part of the general aging process, some of these crystals can break off. When that happens, they can make their way into the semicircular canals of the inner ear. These canals are designed to be one way in and one way out, so once a crystal is in there, movements like lying down or sitting up disrupt the fluid inside the canal. That disruption in fluid movement is what produces the spinning sensation of vertigo.
What Does BPPV Actually Feel Like?
BPPV symptoms are triggered by specific head positions rather than appearing at random. The most common triggers are lying down in bed or rolling over while you’re already lying down.
When triggered, most people experience a sudden room-spinning sensation lasting around five to ten seconds, though it can stretch to thirty seconds or even a full minute in some cases. The symptoms then settle once you stay in that position for a moment or move out of it.
Outside of these specific trigger positions, most people with BPPV feel completely normal. That pattern, brief and intense vertigo tied to a specific movement, followed by a full return to normal, is one of the clearest signs that BPPV is behind your symptoms, rather than another balance condition.
How Is BPPV Diagnosed?
The standard assessment for BPPV is called the Dix-Hallpike manoeuvre. During the test, your physiotherapist turns your head 45 degrees to one side, then guides you from sitting into a lying position with enough pace to create momentum in the inner ear canals.
You need to keep your eyes open throughout because we’ll be looking for a specific eye-movement response called nystagmus. These movements tell us which canal is affected so we can determine the correct treatment approach.
At our clinics, this assessment is supported by vesticam goggles, infrared technology that makes these eye movements far easier to observe and interpret accurately than the naked eye alone. This level of precision is what allows for a treatment plan built around your specific type of BPPV, rather than a generic, one-size-fits-all exercise.
How Is BPPV Treated?
Once the affected canal has been identified, treatment involves a repositioning manoeuvre.
These manoeuvres work by using gravity to guide the displaced crystals back out of the canal, so they can be naturally reabsorbed by the body. The Epley manoeuvre generally follows a sequence of positions:
- Turning the head toward the affected side and lying back
- Rolling the head through a series of angles while lying down
- Rolling onto the opposite side with the head angled toward the floor
- Returning to an upright sitting position.
Each position is typically held for at least 30 seconds, and longer if any dizziness or nystagmus is still settling.
This isn’t a manoeuvre most people should attempt to self-diagnose and perform without guidance, since using the wrong sequence for the wrong canal is unlikely to help and can be disorientating. It’s why an accurate assessment always comes before treatment.

Why an Accurate Diagnosis Matters
BPPV isn’t a single, uniform condition. It has several variants depending on which canal in the inner ear is affected, and the correct repositioning manoeuvre depends entirely on identifying the right one. A manoeuvre chosen for the wrong canal is unlikely to bring the same results.
This is also why generalised approaches, such as habituation-based exercises people often try at home, tend to work more slowly and inconsistently than a manoeuvre matched to the specific canal involved.
And it’s also the reasoning behind our approach at the Headache, Neck and Jaw Clinic. Combining a detailed history with hands-on testing and vesticam goggle technology allows us to pinpoint exactly which canal is involved before recommending treatment, which is why complete resolution is typically achieved within one to three sessions.
Don’t Let Vertigo Control Your Life
BPPV can feel alarming when it hits, but it’s one of the most treatable causes of vertigo once it’s properly identified. If you’ve been experiencing sudden spinning sensations tied to specific head positions, our physiotherapists can assess exactly what’s going on and get you on the fastest path to relief.

Frequently Asked Questions
What does BPPV feel like?
BPPV typically causes a sudden spinning sensation triggered by specific head movements, such as lying down or rolling over in bed. Episodes usually last five to thirty seconds, sometimes up to a minute, before settling. Most people feel completely normal outside of these trigger positions.
What causes BPPV?
BPPV is caused by tiny calcium carbonate crystals dislodging from their normal position in the inner ear and moving into one of the semicircular canals. This can happen due to head trauma or simply as part of the natural aging process.
How is BPPV diagnosed?
BPPV is diagnosed using the Dix-Hallpike manoeuvre, which involves specific head and body positioning to trigger and observe eye movements called nystagmus. At the Headache, Neck and Jaw Clinic, this is supported by vesticam goggles to precisely identify which inner ear canal is affected.
Can BPPV go away on its own?
Some cases of BPPV can settle without treatment over time, but this can take weeks and there’s no guarantee it will resolve on its own. A proper assessment and targeted repositioning manoeuvre generally offers a faster and more reliable path to relief.
