The Interacoustics TRV Chair is an innovative approach to the diagnosis and treatment of Benign Paroxysmal Positional Vertigo (BPPV). This blog explores the practical benefits the TRV Chair offers in a clinical setting.
Hear from Dr. Alaina Bassett, AuD., PhD., Assistant Professor at California State University, Los Angeles about her experience with the TRV chair.
All types of BPPV can be treated: The TRV Chair facilitates the treatment of all types of BPPV. With its ability to move 360° in all semicircular canal planes and monitor patient eye movements, the chair ensures that any form of BPPV can be effectively addressed.
Patient safety: Because of the safety features of the chair, patients feel very secure while going through an evaluation and treatment process. During treatment maneuvers, patients are secured using a four-point harness. The unique design of the TRV chair means that even individuals with limited mobility due to neck or back issues, or those who are frail, can undergo successful treatment in the TRV Chair. This contrasts with traditional bedside BPPV treatments that may pose challenges for such patients.
Real-time precision: The TRV Chair empowers clinicians to make real-time manual adjustments during treatments. Studies, including those by West et al (2019), emphasize the significant improvement experienced by patients with refractory BPPV through treatments in the TRV Chair. The ability to tailor treatments contributes to enhanced patient outcomes and overall satisfaction.
Potentiated Impact Treatments: The TRV Chair introduces optional potentiated “impact” treatment procedures, incorporating decelerations as liberatory forces for a more natural approach to BPPV treatment. Research by Richard-Vitton et al (2016) highlights how these decelerations aid in dislodging otoconia particles, facilitating debris migration through the semicircular canal during BPPV treatment. Such treatments have proven effective even in challenging cases like cupulolithiasis horizontal canal BPPV.
The Interacoustics TRV Chair emerges as a transformative tool in BPPV care, offering safety, precision, and natural treatment options. As healthcare professionals continue to explore its applications, the TRV Chair stands at the forefront of advancing BPPV diagnostics and treatments.
