Vestibular Rehabilitation and Management
Vestibular rehabilitation is an exercise-based approach that uses the brain's capacity to adapt and compensate to reduce dizziness and improve balance and gaze stability after vestibular injury. Alongside specific physical manoeuvres for positional vertigo, it is a central non-pharmacological strategy for many chronic and incompletely compensated vestibular disorders.
Definition
Vestibular rehabilitation is a structured programme of head, eye, and balance exercises designed to drive central vestibular compensation and reduce symptoms in people with vestibular hypofunction or persistent dizziness.
Scope
This topic describes the principles behind vestibular rehabilitation — adaptation, habituation, and substitution — the role of repositioning manoeuvres for positional vertigo, and the broad evidence that exercise-based therapy benefits unilateral peripheral vestibular dysfunction. It is educational and does not prescribe regimens for individuals.
Core questions
- What mechanisms — adaptation, habituation, substitution — underlie recovery?
- How do repositioning manoeuvres differ from general vestibular exercises?
- What does controlled evidence show about exercise-based rehabilitation?
Key concepts
- Vestibular compensation
- VOR adaptation and gaze-stabilisation exercises
- Habituation exercises
- Sensory substitution and balance training
- Canalith repositioning manoeuvres
- Customised, supervised exercise programmes
Mechanisms
After loss or asymmetry of vestibular input, the central nervous system rebalances and recalibrates its responses — a process called vestibular compensation. Rehabilitation drives this through adaptation (exercises that recalibrate the vestibulo-ocular reflex during head movement), habituation (repeated exposure to provoking movements to reduce symptom sensitivity), and substitution (relying more on visual and proprioceptive cues and on alternative strategies for stability). For positional vertigo specifically, mechanical repositioning manoeuvres act differently, guiding displaced otoconia out of the affected canal rather than promoting central adaptation (Epley, 1992; Bhattacharyya et al., 2017).
Clinical relevance
Vestibular rehabilitation is a widely used, non-drug approach for chronic dizziness and vestibular hypofunction, and repositioning manoeuvres are the corresponding physical treatment for positional vertigo. The topic illustrates how the nervous system's plasticity is harnessed therapeutically. This entry is educational and is not a basis for designing an individual's treatment.
History
Exercise-based approaches trace to mid-twentieth-century regimens for restoring balance after vestibular injury and were progressively formalised into customised vestibular rehabilitation. The introduction of the canalith repositioning procedure in 1992 added a targeted mechanical treatment for positional vertigo, and systematic reviews later assembled the controlled evidence supporting exercise-based rehabilitation for unilateral peripheral vestibular dysfunction.

Frequently asked questions
- What is vestibular rehabilitation?
- It is an exercise-based therapy using head, eye, and balance exercises that promote the brain's compensation for vestibular problems, with the aim of reducing dizziness and improving stability and gaze control.
- Is vestibular rehabilitation the same as the manoeuvres used for positional vertigo?
- No. Repositioning manoeuvres physically move displaced inner-ear particles out of a semicircular canal to resolve positional vertigo, whereas vestibular rehabilitation exercises work by driving central adaptation, habituation, and substitution over time.
