This prospective, randomized, open-label study compared the Thomas Richard Vitton (TRV) rotational chair with manual maneuvers in patients with uncomplicated benign paroxysmal positional vertigo (BPPV), with outcomes monitored over 12 months. Among 89 patients who completed follow-up, the groups did not differ significantly in the mean number of maneuvers needed for resolution (TRV: 2.25 ± 1.78; manual: 1.82 ± 1.23; p = 0.190). Both groups improved in dizziness-related quality of life and symptom scores, without significant between-group differences. The authors report comparable efficacy overall.
Key findings
- Mean maneuvers for resolution were TRV: 2.25 ± 1.78 and manual: 1.82 ± 1.23 (p = 0.190).
- DHI scores declined in both groups, with no inter-group difference (p > 0.05).
- VAS scores declined in both groups, with no inter-group difference (p > 0.05).
- Osteoporosis and prior BPPV episodes were associated with higher recurrence (p = 0.002).
Why it matters
The findings indicate that a rotational chair can achieve outcomes comparable to manual repositioning for uncomplicated BPPV, while offering an alternative when mobility constraints make manual maneuvers difficult. The study also identifies factors associated with recurrence and greater maneuver requirements, which may help clinicians frame expectations and follow-up discussions, although these associations do not establish causation.
What to keep in mind
Thirteen of the 102 assigned patients did not complete follow-up. The study was open-label, and the reported faster resolution among patients over 65 treated with the chair was a trend rather than a demonstrated significant advantage.
