Understanding BPPV: A Physiotherapist’s Guide to Causes and Treatment

Benign Paroxysmal Positional Vertigo (BPPV) is a common inner ear condition that leads to sudden and intense dizziness. As physiotherapists, we frequently help patients manage and treat BPPV using specialised techniques that target the root cause of their symptoms. Understanding BPPV, its causes, and treatment options can help those affected regain control of their balance and daily activities.


Benign Paroxysmal Positional Vertigo (BPPV) is a common inner ear condition that leads to sudden and intense dizziness.

What is BPPV?


BPPV occurs when tiny calcium carbonate crystals, called otoconia, become dislodged from their usual position in the inner ear and move into the semicircular canals. These canals are responsible for detecting head movement, and when debris disrupts normal fluid flow, it leads to false signals being sent to the brain, causing vertigo.


Common Causes of BPPV


  • Head Trauma: A blow to the head can dislodge otoconia.

  • Age-Related Changes: Degeneration of the inner ear structures increases risk with age.

  • Prolonged Head Positioning: Sleeping in one position for long periods or extended bed rest.

  • Idiopathic (Unknown Causes): Many cases of BPPV occur without a clear trigger.

Symptoms of BPPV


  • Sudden Vertigo: A spinning sensation triggered by head movements.

  • Nausea and Dizziness: Accompanying feelings of imbalance.

  • Loss of Balance: Increased risk of falls, particularly in older adults.

  • Brief Duration: Symptoms typically last less than a minute but can recur with certain movements.

How is BPPV Diagnosed?


A physiotherapist performs a thorough assessment, including:

  • Dix-Hallpike Test: A positional test to provoke vertigo and observe eye movements (nystagmus).

  • Head Roll Test: Used for diagnosing horizontal canal involvement.


Physiotherapy Treatment for BPPV


1. Canalith Repositioning Manoeuvres

These are specific movements designed to guide the dislodged crystals back to their correct position in the inner ear.

  • Epley Manoeuvre: The most common and effective technique for posterior canal BPPV.

  • Semont Manoeuvre: A rapid side-to-side movement technique for repositioning crystals.

  • Brandt-Daroff Exercises: Performed at home to help habituate the vestibular system.


2. Vestibular Rehabilitation Therapy (VRT)

For patients with persistent dizziness, physiotherapists may prescribe customised exercises to improve balance, gaze stability, and habituate the brain to dizzy sensations.


Post-Treatment Care: Avoid sudden head movements for 24 hours after repositioning manoeuvres.

3. Education and Lifestyle Modifications

  • Post-Treatment Care: Avoid sudden head movements for 24 hours after repositioning manoeuvres.

  • Sleep Positioning: Elevating the head slightly while sleeping may help prevent recurrence.

  • Hydration and Regular Movement: Staying active with controlled movements can reduce dizziness episodes.


When to Seek Further Medical Attention


If symptoms persist despite physiotherapy treatment, or if dizziness is accompanied by severe headaches, double vision, weakness, or difficulty speaking, a referral to a specialist may be necessary to rule out other neurological conditions.


Conclusion


BPPV is a highly treatable condition, and physiotherapists play a vital role in providing effective, non-invasive interventions. With the right treatment, most patients experience significant relief and can return to normal activities without persistent vertigo. If you are experiencing dizziness, seeking physiotherapy assessment and treatment can help restore your balance and improve your quality of life.
