Should we refer her to vestibular physical therapy after completing the urgent work‑up and treatment of her ear symptoms?

Vestibular Physical Therapy Referral for Ear Symptoms

Yes, you should offer vestibular physical therapy (either self-administered or with a clinician) as a treatment option for BPPV after completing the urgent work-up, though canalith repositioning procedures remain the primary treatment. 1

Treatment Algorithm for BPPV

First-Line Treatment: Canalith Repositioning Procedure (CRP)

• Clinicians should treat, or refer to a clinician who can treat, patients with posterior canal BPPV with a canalith repositioning procedure (Epley maneuver) 1
• This is a strong recommendation with approximately 80% success rates with only 1-3 treatments 2
• The CRP should be performed at the same visit as diagnostic testing when possible 2

When to Consider Vestibular Physical Therapy

Vestibular PT is an OPTION (not a requirement) and may be offered in the following scenarios:

1. As adjunctive therapy alongside or after CRP 1

2. For patients with modifying factors that increase complexity 1:

   • Impaired mobility or balance
   • Central nervous system disorders
   • Lack of home support
   • Increased risk for falling
   • Seniors with history of falls or fear of falling 2

3. For persistent symptoms after initial CRP treatment 1

4. To potentially reduce recurrence rates, particularly in elderly patients 3

Evidence Strength and Nuances

The 2017 AAO-HNS guideline classifies vestibular rehabilitation as an "Option" rather than a "Recommendation" or "Strong Recommendation" 1. This reflects important evidence limitations:

• Short-term effectiveness: Vestibular rehabilitation is less effective than CRP for producing complete symptom resolution initially 3
• Long-term effectiveness: With longer follow-up, vestibular rehabilitation effectiveness approaches that of CRP 3
• No superiority data: Current evidence cannot determine if formal outpatient therapy with a clinician is superior to independent home-based therapy 3

Practical Implementation

Self-administered vs. clinician-supervised therapy:

• Either approach is acceptable 1
• Cost considerations favor home-based therapy after initial instruction 3
• Formal referral to a vestibular physical therapist is particularly warranted for:
  • Severe disabling symptoms 2
  • Seniors with fall history or fear of falling 2
  • Patients with difficulty moving (joint stiffness, weakness) 2

Common Pitfalls to Avoid

1. Don't use vestibular PT as first-line monotherapy when CRP is available and appropriate—CRP has stronger evidence and faster results 1, 3

2. Don't refer for formal vestibular testing in patients who meet diagnostic criteria for BPPV without additional inconsistent signs/symptoms 1

3. Don't prescribe vestibular suppressant medications (antihistamines, benzodiazepines) routinely for BPPV 1

4. Recognize contraindications to certain maneuvers: cervical stenosis, Down syndrome, severe rheumatoid arthritis, cervical radiculopathies, Paget's disease, morbid obesity, ankylosing spondylitis, low back dysfunction, spinal cord injuries 3

Follow-Up Requirements

Reassess within 1 month after initial treatment to document resolution or persistence of symptoms 1. If symptoms persist, evaluate for unresolved BPPV and/or underlying peripheral vestibular or central nervous system disorders 1.
