Vestibular Rehabilitation: Habituation Exercises and Step-by-Step VR Protocol
Vertigo leads to medical consultation, activity cessation or sick leave in 80% of cases [1].
The meta-analysis by Heffernan et al. identifies a standardized mean difference of 1.13 (95% CI: −1.74; −0.52) in favor of a reduction in DHI (Dizziness Handicap Inventory) in patients treated with virtual reality (VR) compared to control groups [2]. Improvements in the physical domain of the DHI and in the ABC scale (Activities-specific Balance Confidence) are significantly more pronounced in the VR group than in the control group [3]. Vestibular rehabilitation exercises in VR truly change the game for your patients.
The daily challenge of vestibular rehabilitation in the clinic
Dizziness and chronic postural instability are among the most complex complaints to manage in outpatient physiotherapy.
Vestibular Rehabilitation Therapy (VRT) is an exercise-based approach designed to accelerate the natural process of vestibular compensation, indicated in acute and chronic non-progressive peripheral vestibulopathies.
Its fundamental principle rests on three neuroplastic mechanisms: adaptation, habituation and sensory substitution. These mechanisms address a variety of conditions — vestibular neuritis, unilateral or bilateral hypofunction, visual dependency, PPPD (Persistent Postural-Perceptual Dizziness) — well beyond BPPV (Benign Paroxysmal Positional Vertigo) alone.
Conventional VRT requires numerous in-person appointments, is time-consuming and resource-intensive. Patient compliance, particularly among those with low exercise tolerance, remains a major barrier to its effectiveness.
This is precisely where VR comes in as a clinical tool: it allows every step of rehabilitation to be dosed, graded and objectively measured, session after session.

Three pillars of vestibular rehabilitation exercises: the mechanisms at play
Classical VRT is organized around three principles: (1) habituation, achieved through repetitive movements to reduce sensitivity to stimuli; (2) adaptation exercises designed to recalibrate the vestibulo-ocular reflex (VOR) by correcting retinal slip; (3) sensory substitution exercises that strengthen the use of the visual and somatosensory systems to compensate for reduced vestibular function.
These three pillars are not theoretical: they concretely guide the construction of the protocol session by session.
1. Habituation: Vestibular rehabilitation consists of exercises combining head movements with gaze stabilization and balance training, aimed at helping the vestibular system adapt, habituate or compensate for deficits. In VR, the immersive environment allows the triggering stimuli to be precisely reproduced and their intensity adjusted with a granularity impossible to achieve with Cawthorne-Cooksey or Brandt-Daroff exercises.
2. Gaze stabilization (VOR): Active eye and head movements while maintaining focus on a target promote recovery by recalibrating the VOR, helping to restore function.
Gaze stability exercises in VR are based on head movements while maintaining fixation on a target, either fixed or moving. The headset positions this target in three-dimensional space and records movement accuracy in real time.
3. Sensory substitution: Control of gaze stabilization mechanisms becomes crucial. A reduction in VOR reinforcement can lead to an adaptive shift toward the optokinetic reflex (OKR). VR allows the contribution of each sensory modality (visual, vestibular, proprioceptive) to be manipulated with a precision that conventional tools cannot offer.

Patient profile: who to refer for vestibular rehabilitation in VR?
Numerous studies have examined the effects of VR in vestibular rehabilitation for various conditions, including unilateral and bilateral vestibular hypofunction, as well as residual symptoms following BPPV. VR is also suitable for patients suffering from PPPD, motion sickness, or visual dependency.
Parameter | Value |
|---|---|
Target condition | Unilateral or bilateral vestibular hypofunction |
Other indications | PPPD, vestibular neuritis, visual dependency, motion sickness |
Exclusion profile | Epilepsy, severe oculomotor disorders, visual acuity < 1/10 |
Age | Adult ≥ 18 years, validated up to elderly patients |
Minimum physical condition | Able to stand without assistance |
Recommended assessment tools | DHI, VAS (Visual Analogue Scale), TUG (Timed Up and Go), BBS (Berg Balance Scale) |
Inclusion criteria retained in clinical trials include adults presenting symptoms related to a vestibular disorder, able to stand without assistance; exclusion criteria include visual acuity below 1/10, absence of depth perception, severe strabismus, oculomotor disorders or a history of epilepsy.
Initial assessment with the DHI — a validated questionnaire measuring the functional, emotional and physical impact of dizziness — is essential before any treatment. It will provide your baseline to objectively track progress.

Vestibular rehabilitation exercise protocol in VR: session-by-session progression
VR has emerged as a promising tool in vestibular rehabilitation, offering immersive and interactive environments that enhance patient engagement and therapy adherence. Its potential lies in delivering controlled and customizable exercise protocols, simulating real-world challenges in a safe, supervised environment.
Here is how to structure the clinical progression:
1. Phase 1 — Assessment and calibration (session 1): Assess the DHI, TUG and tolerance to immersion. Identify the dominant triggering stimuli (horizontal or vertical head movements, optical flow, complex environments). Set the initial intensity at the lowest level.
2. Phase 2 — Habituation and basic VOR (sessions 2 to 4): The patient repeats gaze manipulation exercises (X1, X2) in the headset. The goal is to improve VOR gain. The level of difficulty — stimulus speed, range of head movement, background complexity — is gradually increased according to tolerance.
3. Phase 3 — Graded optokinetic stimulation (sessions 5 to 8): Optokinetic stimulation (OKS) is used in awareness and adaptation exercises. In VR, optical flows — animated corridors, supermarket scenes, moving crowds — are presented at gradually increasing speeds. The VR exercise program improves dizziness, quality of life and walking function (TUG), and additional optokinetic stimuli are particularly beneficial for individuals presenting visual vertigo symptoms.
4. Phase 4 — Dynamic balance and consolidation (sessions 9 to 12): These exercises improve the patient's overall balance, through static and dynamic balance tasks in virtual environments. The patient progresses: standing on a stable surface → on foam → walking through the virtual environment.
5. Phase 5 — Reassessment and empowerment (session 12+): Reassess the DHI, TUG and BBS. Compare with initial values. Determine whether a home maintenance phase is indicated, adjusting supervision accordingly.
Protocol parameter | Recommended value |
|---|---|
Total duration | 4 to 8 weeks |
Number of sessions | 8 to 12 sessions |
Frequency | 2 sessions per week |
Duration per session | 20 to 40 minutes |
Supervision | Physiotherapist present during session, progression validated session by session |
Monitoring tools | DHI, VAS, TUG, BBS |
A standard 4-week protocol with 2 sessions per week (8 sessions total), each lasting 30 to 40 minutes, represents a schema validated in the literature for VR vestibular rehabilitation.
⚠️ Key point: Progression must always be guided by the patient's tolerance, not by a fixed schedule. Adverse effects reported in studies generally decrease by the fourth week of VR intervention. If cybersickness (nausea, discomfort) occurs, reduce session duration and optical flow intensity before resuming progression.
What the studies say: the clinical evidence for vestibular rehabilitation in VR
Studies have shown that VRT using virtual reality is effective, with meta-analyses confirming its superiority over conventional methods.
On DHI: DHI scores at 0–3 months post-intervention were reported by four studies. The meta-analysis identifies a standardized mean difference of 1.13 (95% CI: −1.74; −0.52) in favor of a reduction in DHI in groups treated with VR and augmented reality compared to control groups [2].
On speed of effect: Improvements in the physical domain of the DHI and in the ABC scale are significantly more pronounced in the VR group, reflecting increased confidence in movement and a reduction in the perceived physical handicap related to dizziness [3].
On comparison with conventional exercises: In a study involving 124 patients presenting residual symptoms following BPPV, the VR group showed significantly greater reductions in DHI and VSI (Vertigo Symptom Index) scores compared to the Cawthorne-Cooksey and Brandt-Daroff groups. Furthermore, the VR group demonstrated better balance (BBS) and reduced anxiety [4].
On safety: No significant adverse effects, including no major cybersickness, incidents or falls, were reported in the studies.
These data should however be interpreted with nuance. While VR is being explored in vestibular rehabilitation, consensus on its systematic superiority over traditional vestibular physiotherapy is still being established. VR is used as a complement to a structured clinical approach, not as a substitute for your expertise.
💡 Key takeaway: VR in vestibular rehabilitation is not merely a comfort tool for the patient. It is a clinical tool for precise dosing: you control the type of stimulus, its intensity, its duration and its sensory context — something no paper-and-pencil exercise can achieve. Repeated DHI measurement across sessions transforms your clinical impression into objective data that can be shared with the referring physician.

FAQ — Vestibular rehabilitation exercises in virtual reality
Which vestibular patients are the best candidates for VR rehabilitation?
Patients presenting unilateral or bilateral vestibular hypofunction and residual post-BPPV symptoms are among the best-documented indications. Patients suffering from PPPD, visual dependency or motion sickness also represent very strong profiles, as VR allows precise control of the triggering visual flow. An initial assessment with DHI, TUG and BBS is essential before starting.
How many sessions are needed to observe an improvement in DHI?
Improvements in the physical domain of the DHI and the ABC scale can be significantly faster in the VR group. A total rehabilitation duration of more than 4 weeks helps to reduce dizziness and reinforce its benefits, with emotional improvements observable as early as 2 weeks. A protocol of 8 to 12 sessions over 4 to 8 weeks constitutes the reference schema in the literature.
Do habituation exercises in VR cause cybersickness?
Studies report no significant adverse effects, including no major cybersickness, incidents or falls. A slight initial increase in symptoms is expected and is part of the habituation mechanism. It generally decreases before the end of the first month of treatment. Physiotherapist supervision during sessions remains essential for real-time adjustment.
Is optokinetic stimulation in VR indicated in all vestibular cases?
Additional optokinetic stimuli are particularly beneficial for individuals presenting visual vertigo symptoms, such as in PPPD or visual dependency. For pure vestibular hypofunction without a dominant visual component, VOR gaze stabilization and habituation exercises constitute the primary foundation.
How can vestibular rehabilitation in VR be integrated into an outpatient clinic without complex infrastructure?
VR can be applied as a home or clinic-based therapy to maintain vestibular compensation, and current devices are compact and standalone. KineQuantum offers a clinical tool requiring no hospital infrastructure, designed to integrate into a standard physiotherapy clinic — visit the KineQuantum Liberté page to learn more.
