Repositioning maneuvers performed with the TRV chair for benign paroxysmal positional vertigo: a systematic review

Background Benign paroxysmal positional vertigo (BPPV) is one of the most common disorders affecting vestibular system. The TRV (Thomas Richard-Vitton) chair enables patients to rotate 360° in all planes while maintaining a fixed sitting position. This review aims to examine the effects of TRV chairs in patients with BPPV, identify treatment success rates, recurrence rates, and the number of maneuvers required for recovery. Methods PubMed, SCOPUS, MEDLINE, PEDro, REHABDATA, and Web of Science databases were searched from inception to October 2025. Studies that involved individuals with BPPV who received TRV chair intervention, compared with active, passive, or no controls, evaluated BPPV recovery and were included in this review. The methodological quality of the included studies was assessed using the Newcastle–Ottawa Scale (NOS). Results Ten studies met the inclusion criteria, with a total of 2204 individuals (mean age 58.84 years; 66% were female) diagnosed with BPPV were included in this review. The included studies ranged from 4 to 6, with a median score of 5/9. The main findings revealed that administering repositioning maneuvers with TRV chairs is an effective for treating BPPV. Conclusions Repositioning maneuvers performed with the TRV chair are effective and safe for treating patients with BPPV. The overall means of required treatments for unilateral BPPV is 2.16 times, with a successful rate was 91.1% and a recurrence rate of about 22.5%. However, further high-quality studies are needed to standardize TRV chair protocols, including long-term follow-ups, and evaluate clinical applicability to define its role in vestibular rehabilitation.
