From the Guidelines
Vestibular physical therapy, specifically canalith repositioning maneuvers, is the recommended first-line treatment for benign paroxysmal positional vertigo (BPPV). The most effective treatment involves the Epley maneuver for posterior canal BPPV or the Lempert roll for horizontal canal BPPV, which should be performed by a trained vestibular physical therapist who can properly diagnose the affected canal and perform the appropriate repositioning technique 1.
Key Components of Treatment
- Treatment typically requires 1-3 sessions, with most patients experiencing complete resolution after just one properly executed maneuver.
- Following treatment, patients should remain upright for 24-48 hours and avoid sleeping on the affected side for a week to prevent otoconia from returning to the semicircular canals.
- Home exercises like the Brandt-Daroff exercises may be prescribed for ongoing management.
Rationale for Treatment
BPPV occurs when calcium carbonate crystals (otoconia) become dislodged from the utricle and enter the semicircular canals, causing inappropriate endolymph movement and resulting vertigo with position changes. The repositioning maneuvers work by moving these displaced crystals out of the semicircular canals and back into the vestibule where they can be reabsorbed.
Evidence Supporting Treatment
The effectiveness of vestibular rehabilitation for BPPV has been demonstrated in several studies, with some showing superior treatment outcomes compared to placebo 1. While there is limited evidence to favor one form of vestibular rehabilitation over another, or to favor formal outpatient vestibular therapy over independent home therapy, the available data support the use of vestibular physical therapy as a first-line treatment for BPPV 1.
Considerations for Treatment
Cost considerations and patient comorbidities, such as cervical stenosis or severe rheumatoid arthritis, may influence the choice of treatment and the need for specialized or individually tailored vestibular rehabilitation protocols 1. However, for most patients, vestibular physical therapy is a safe and effective treatment option for BPPV.
From the Research
Treatment Options for BPPV
The treatment for Benign Paroxysmal Positional Vertigo (BPPV) using vestibular physical therapy (PT) includes various maneuvers, such as:
- Semont's manoeuvre
- Epley's manoeuvre
- Brandt-Daroff exercises
- Gufoni's maneuvers
Efficacy of Treatment Options
Studies have shown that these maneuvers are effective in treating BPPV, with the Epley manoeuvre appearing to be more effective than the other two in terms of relief of symptoms and prevention of recurrence 2. The choice of maneuver depends on the clinician's preferences, failure of the previous maneuver, or movement restrictions of the patient 3.
Comparison of Treatment Options
Comparative studies have shown that the Epley manoeuvre, modified canalith repositioning maneuver (CRP), and Brandt-Daroff exercise are all effective interventions for BPPV, with no significant difference between them 4. The Epley manoeuvre has also been shown to be effective in treating posterior canal BPPV, with a significant reduction in vertigo intensity and frequency 5.
Role of Physical Therapy
Physical therapy plays a crucial role in the treatment of BPPV, with maneuvers being the primary evidence-based treatment strategy 3. The treatment approach should be individualized, taking into account the patient's specific needs and preferences. Chair-assisted treatment may be helpful in some cases, while surgical canal plugging may be indicated in selected cases of intractable severe BPPV 3.
Key Findings
Key findings from the studies include:
- The Epley manoeuvre is a safe and effective treatment for posterior canal BPPV 5
- The choice of maneuver depends on the clinician's preferences, failure of the previous maneuver, or movement restrictions of the patient 3
- Physical therapy is the primary evidence-based treatment strategy for BPPV 3
- There is a need for further research to identify the optimum maneuvers for variants of BPPV whose diagnosis and treatment are still a matter of debate 3
