What the TRV Chair is used for

The TRV Chair supports precise evaluation and treatment of positional vertigo by allowing controlled movement through multiple axes. It can help when standard maneuvers are not enough or when the canal involvement is unclear.

Why it matters

Complex BPPV can involve unusual canal patterns, intense symptoms, or limited mobility that makes bedside repositioning difficult. Chair-based testing and treatment can improve precision and patient safety.

What patients can expect

  • The patient is secured with supports before movement begins.
  • The clinician observes symptoms and eye movements during specific positions.
  • Treatment is selected based on the observed vertigo and nystagmus pattern.
