Highlights
- Rotational chairs and manual maneuvers demonstrate comparable efficacy in resolving uncomplicated BPPV symptoms.
- Quality-of-life improvements, measured by DHI and VAS, are significant and similar with both interventions.
- Older patients may benefit from faster symptom resolution using rotational chair therapy.
- Risk factors such as osteoporosis and prior BPPV episodes increase recurrence risk, guiding personalized management.
Background
Benign Paroxysmal Positional Vertigo (BPPV) is a common vestibular disorder characterized by brief episodes of vertigo triggered by changes in head position. It results primarily from otoconial debris dislodged into the semicircular canals, most frequently the posterior canal. BPPV imposes a substantial burden on patients due to dizziness-induced functional limitations, fall risk especially in older adults, and impact on quality of life (QoL).
Management traditionally centers on manual repositioning maneuvers such as the Epley or Semont procedure, which aim to relocate canaliths to the utricle. More recently, mechanical rotational chairs like the Thomas Richard Vitton (TRV) chair offer an alternative by standardizing head and body positioning with controlled rotational movements, potentially improving diagnostic precision and therapeutic efficacy.
Despite their theoretical advantages, the clinical superiority of rotational chairs over manual maneuvers in uncomplicated BPPV remains unclear. Addressing this gap, the study by Chaure-Cordero and Martin-Sanz (2026) provides prospective randomized data comparing these modalities.

Chronological and Methodological Context of BPPV Interventions
The initial description of BPPV and the pioneering treatments date back to the 1950s and 1980s. Manual maneuvers became standard due to their non-invasiveness and high success rates. Over the past two decades, rotational chairs with video nystagmography have enhanced diagnostic clarity and allowed precise positional testing under controlled rotational stimulation.
Randomized controlled trials (RCTs) and meta-analyses have repeatedly affirmed the efficacy of manual repositioning maneuvers with cure rates often exceeding 80%-90% after a few sessions. Mechanical rotational chairs introduced in the late 1990s have been studied primarily in complex or refractory BPPV, with indications suggesting benefits in cases with mobility restrictions or diagnostic difficulty.
Evidence Comparing Rotational Chair vs. Manual Maneuvers in Uncomplicated BPPV
The recent prospective randomized open-label study by Chaure-Cordero et al. (2026) randomized 102 patients with non-complex BPPV to either TRV chair treatment or manual maneuvers. Clinical resolution rates, mean number of maneuvers to achieve remission, recurrence rates, and QoL metrics were assessed over a 12-month period.
– Clinical Resolution and Maneuver Frequency: No significant difference existed between groups regarding mean maneuvers to resolution (TRV: 2.25 ± 1.78 vs. manual: 1.82 ± 1.23; p=0.190).
– Quality of Life Outcomes: Both groups experienced significant improvements in Dizziness Handicap Inventory (DHI) scores and visual analog scale (VAS) for dizziness severity (p<0.001), with no inter-group statistical difference.
– Subgroup Findings: A trend toward faster symptom remission was noted in patients aged over 65 undergoing rotational chair therapy, suggesting potential utility in older populations with mobility limitations.
– Risk Factor Analysis: Advanced age and history of head trauma correlated with increased number of maneuvers needed. Osteoporosis and prior BPPV episodes were statistically associated with higher recurrence risk (p=0.002).
– Episode Duration and Recurrence: An inverse correlation between duration of initial vertigo episode and time to first recurrence was demonstrated (ρ=–0.539, p=0.005), informing prognosis.
These findings align with earlier smaller-scale studies and systematic reviews indicating the therapeutic equivalence between mechanical and manual interventions in primary BPPV, while highlighting specific patient profiles that may benefit differentially.
Diagnostic and Mechanistic Insights
Rotational chairs enhance assessment precision by providing controlled, reproducible head rotations, facilitating nystagmus visualization via video-oculography. This feature assists in canalith repositioning and accurate subtype diagnosis, potentially reducing misclassification and inappropriate treatment application.
However, in uncomplicated BPPV, the benefit of this enhanced diagnostic capacity does not necessarily translate into statistically significant improved clinical outcomes, as reflected in the primary study. This may be related to the efficiency of manual maneuvers when performed by experienced clinicians.
Implications for Clinical Practice and Resource Utilization
Manual maneuvers remain the mainstay due to accessibility, cost-effectiveness, and established efficacy. Rotational chairs represent a complementary resource, especially suited to patients with physical or mobility restrictions preventing effective cooperation with manual techniques.
Furthermore, the documented association of osteoporosis and previous BPPV episodes with recurrence suggests need for tailored follow-up and possibly adjunctive preventative strategies in these patients. Consideration for patient history, age, and trauma exposure can refine management algorithms.
Expert Commentary
The study by Chaure-Cordero et al. fills an important evidence gap by rigorously comparing rotations chairs and manual maneuvers in a prospective randomized design applicable to routine clinical populations. Despite the lack of statistically significant superiority of the TRV chair, the nuanced finding of accelerated resolution in elderly patients is clinically meaningful given their heightened fall risk and frequent comorbidities.
Clinical guidelines, including those from AAO-HNS and Barany Society, endorse repositioning maneuvers as first-line treatments, reserving technological aids for complex, refractory, or atypical presentations. This study substantiates such recommendations while supporting inclusion of rotational chairs as a valuable adjunct in resource-equipped centers.
Mechanistically, the success of both interventions reaffirms the pathophysiological model of canalith repositioning as central to symptom resolution. The identification of risk factors influencing recurrence and treatment response provides a foundation for personalized management paradigms.
Limitations include the open-label design and sample size, warranting larger, multicenter trials. Future research should investigate the cost-benefit analysis, patient satisfaction, and long-term outcomes of rotational chair use.
Conclusion
Current evidence indicates that in uncomplicated BPPV, mechanical rotational chairs and manual repositioning maneuvers both achieve effective clinical resolution and significant quality-of-life improvements. Rotational chairs do not confer statistically significant advantages overall but may expedite symptom resolution in elderly populations and serve those with mobility challenges.
Attention to risk factors such as osteoporosis and prior BPPV episodes is vital for anticipating recurrence and optimizing follow-up care. Clinicians should consider patient characteristics and resource availability when selecting therapeutic modalities.
Continued comparative effectiveness research and integration of mechanistic insights will enhance precision vestibular medicine and improve patient-centered outcomes in BPPV management.
