Vestibular rehabilitation,
does it really help with Reduced chronic vestibular dizziness and related disability?
research showsVestibular rehabilitation is rated B because it reduces chronic vestibular dizziness and related disability. Yardley 2004 randomized 170 participants and used baseline-observation-carried-forward imputation for losses, so the actual intention-to-treat primary analysis also included all 170. The co-primary measures of dizziness symptoms, movement-provoked dizziness, postural stability, and disability all improved significantly at three months, making the primary assessment successful. A Cochrane review of 39 randomized trials and 2,441 participants also supported improvements in dizziness frequency and disability, but heterogeneity in diagnoses, exercises, and controls plus a failed primary analysis in a later trial limits the grade to B with 68 points.

Central neurologic disease, cardiovascular causes, medicines, migraine, and acute stroke warning signs require differentiation. Canalith repositioning for positional vertigo and rehabilitation exercise for chronic vestibular dysfunction are different interventions.
Useful facts when choosing a product
- Vestibular rehabilitation can combine gaze stabilization, graded head-movement adaptation, repeated symptom-provoking movements, balance training, and gait training.
- Exercises can transiently provoke dizziness early in treatment, making correct diagnosis and graded progression important.
- New neurologic deficits, severe headache, inability to walk, chest pain, or syncope accompanying acute dizziness require urgent assessment before exercise.

What the research actually shows
Yardley 2004 (Ann Intern Med 141(8):598-605) randomized 170 people with chronic dizziness to nurse-delivered vestibular rehabilitation or usual care and retained all 170 in an intention-to-treat analysis; the adjusted three-month VSS difference was -3.48 points (95% CI -5.59 to -1.38), P=0.001. McDonnell 2015, Cochrane 2015(1):CD005397, assessed 39 randomized trials and 2,441 participants; dizziness frequency across four trials and 565 participants had OR 2.67 (95% CI 1.85 to 3.86). Cochrane described the overall evidence as moderate to strong and medium-term symptom and function evidence as moderate. Yardley 2012 (BMJ 344:e2237) was an unblinded booklet-based exercise trial with a failed primary analysis in one arm.
Why this is classified as B (68)
The Yardley trial retained all 170 randomized participants in its intention-to-treat primary analysis and succeeded across its co-primary measures, while 39 randomized trials and 2,441 participants reproduced direct symptom and disability improvement. Clinical and intervention heterogeneity plus a failed primary analysis in a later large trial give B with 68 points.
Counterpoint. The evidence best fits confirmed peripheral vestibular dysfunction in patients able to practice consistently. A condition such as positional vertigo may call for a more specific repositioning procedure.
Rejudgment record. Cross-check applied — Accepted the 170-person Yardley 2004 intention-to-treat success and McDonnell 2015 Cochrane evidence from 39 trials and 2,441 participants, including dizziness frequency in four trials and 565 participants with OR 2.67, with deductions for unblinded exercise, population, exercise-method and scale heterogeneity, and a failed analysis in Yardley 2012
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduced symptoms of chronic vestibular dizziness | B | Direct VSS outcomes improved in the pivotal trial and pooled evidence. |
| Reduced dizziness-related functional disability | B | DHI and clinically significant improvement rates were reproduced across trials. |
| Improved balance and gait function | B | Objective postural-stability and gait measures improved, although programs were heterogeneous. |
