Virtual Reality Vestibular Rehabilitation for BPPV: Clinical Protocol and DHI Outcomes
- Jun 16
- 9 min read
Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo seen in physiotherapy practice. Yet up to 40% of patients retain residual vertigo after a successful repositioning maneuver, generating real functional disability measured by the DHI (Dizziness Handicap Inventory). A 2024 study of 124 post-BPPV patients shows that vestibular rehabilitation using virtual reality (VR) reduces DHI and VSI (Vertigo Symptom Index) scores significantly better than Cawthorne-Cooksey or Brandt-Daroff exercises alone [1]. The evidence is clear: repositioning maneuvers are only the first clinical act.
The challenge of residual vertigo after repositioning maneuvers
BPPV is a condition you treat on a daily basis. The Epley or Semont maneuver repositions the otoliths, suppresses positional nystagmus, and often provides the patient with immediate relief.
Yet the follow-up appointment sometimes holds a surprise: the patient still complains of imbalance, a floating sensation, or instability when walking. This presentation corresponds to post-BPPV residual vertigo, a clinically distinct phenomenon from recurrence.
A peripheral vestibular asymmetry induced by BPPV can trigger new central adaptation. This adaptation becomes all the more entrenched the longer the otoliths remained in an abnormal position. The brain then fails to rapidly readapt to the previous pattern after resolution, generating persistent vertigo.
It is precisely in this post-maneuver context that virtual reality vestibular rehabilitation finds its full purpose: complementing mechanical treatment with targeted sensory rehabilitation.

Why measure the DHI: the reference tool for objectifying vestibular disability
Before building a protocol, you need a quantified starting point. The DHI (Dizziness Handicap Inventory) is a 25-item questionnaire grouped into three dimensions: physical, functional, and emotional.
It assesses a patient's subjective symptoms in functional, emotional, and physical terms. A score of 0 indicates no impairment, while a score of 100 reflects severe perceived disability.
The DHI is now the reference measure in the literature on VR vestibular rehabilitation. Four out of five studies included in a landmark meta-analysis used the DHI score at 0–3 months post-intervention as the primary outcome measure.
In practical terms, a patient who arrives with a DHI of 54 and leaves with a DHI of 19 after their protocol — that is an outcome you can document, substantiate, and communicate to the referring physician. In a study on VR vestibular rehabilitation, mean DHI scores were 54.60 before the program, 19.20 immediately after, and 16.84 at 8 weeks of follow-up (p < 0.001).
This level of traceability is a major asset for your practice, particularly in the context of VR physiotherapy assessments.
Virtual reality vestibular rehabilitation: clinical mechanisms
VR is not an entertainment gadget adapted for healthcare. It acts on precise mechanisms that you need to understand in order to select your protocols.
Vestibular rehabilitation draws on central neuroplasticity mechanisms to improve visuo-vestibular interactions and restore static and dynamic postural stability in situations of sensory conflict.
The immersive environment makes it possible to manipulate the perception of the surroundings to induce sensory mismatch, which has been shown to increase the sensory weight assigned to the vestibular system — a key driver of neuroplasticity and recalibration of the vestibulo-ocular reflex (VOR).
Here are the three mechanisms you concretely address during sessions:
1. Adaptation: adaptation exercises rely on the vestibular system's capacity to modify the amplitude of the vestibulo-ocular reflex (VOR) in response to a specific stimulus, particularly head movements. VR allows this stimulus to be precisely dosed.
2. Habituation: habituation exercises are based on the principle that repeated exposure to provoking stimuli — such as head movements — progressively reduces movement-triggered symptoms. VR generates these stimuli in a controlled and safe environment.
3. Sensory substitution: vestibular rehabilitation improves overall balance functions — gait, gaze stability, postural stability, physical mobility, and functioning in activities of daily living — by integrating residual proprioceptive, visual, and vestibular information.
What the research says: clinical results in numbers
Evidence is accumulating in favor of virtual reality vestibular rehabilitation, and the figures speak clearly.
After treatment, DHI and VSI (vestibular symptom index) scores in the VR, Cawthorne-Cooksey exercise, and Brandt-Daroff exercise groups were all significantly lower than those of the non-intervention control group. VR group scores were additionally lower than those of both conventional exercise groups (p < 0.05). [1]
Among 124 patients presenting with post-BPPV residual symptoms, the VR group (N = 31) showed significantly greater DHI and VSI reductions than the three control groups. The VR group also demonstrated better balance measured by the Berg Balance Test (BBS) and reduced anxiety compared to the control groups. [1]
At the meta-analytic level, convergence is clear. The meta-analysis identified a standardized mean difference of 1.13 (95% CI: −1.74; −0.52) in favor of DHI reduction in VR-treated patients compared to controls. [2]
Regarding speed of effect, 2025 data are encouraging. Improvement in the physical domain of the DHI and ABC (Activities-specific Balance Confidence) scores were significantly faster in the VR group (p = 0.019 for DHI, p = 0.002 for ABC). [3]
Finally, a total vestibular rehabilitation duration of more than 4 weeks can reduce vertigo and enhance therapy benefits. Emotional improvement may be observed as early as 2 weeks. [4]
Parameter | Value |
|---|---|
DHI score before VR (clinical example) | 54.60 / 100 |
DHI score after VR (end of protocol) | 19.20 / 100 |
DHI score at 8 weeks of follow-up | 16.84 / 100 |
Standardized DHI difference (meta-analysis) | −1.13 (95% CI) |
Time to emotional improvement | As early as 2 weeks |
Time to physical improvement (DHI) | Significant from 4 weeks |
💡 Key takeaway: The DHI is not merely a well-being questionnaire. It is a validated clinical measurement tool you can use at intake and discharge to objectively demonstrate the effectiveness of your vestibular management. A variation of 18 points is considered clinically significant in the literature.
Building a concrete protocol: from repositioning maneuver to habituation exercises
Optimal BPPV management unfolds in two distinct phases, and their articulation is what makes the clinical difference.
Phase 1 — The repositioning maneuver: you perform the Epley maneuver (posterior canal) or Gufoni maneuver (horizontal canal) according to the affected canal. The success criterion is abolition of positional nystagmus. This phase may be sufficient in patients without risk factors for residual vertigo.
Phase 2 — Post-maneuver vestibular rehabilitation: this begins as soon as residual vertigo persists beyond 48 to 72 hours. In studies on post-BPPV residual vertigo, patients are recruited once an imbalance persists for 20 days or more after the repositioning procedure. [5]
It is in this phase 2 that VR vestibular rehabilitation intervenes as a clinical tool complementary to manual techniques.
Recommended protocol structure:
1. Initial assessment: administration of the DHI, balance evaluation (Berg Balance Scale — BBS, Timed Up and Go — TUG), anamnesis of aggravating factors (anxiety, post-traumatic context).
2. VR habituation sessions: gradual exposure to visually rich environments (optical flow, scene movement) to desensitize the nervous system to visual-vestibular conflicts. Target duration: 15 to 20 minutes per session.
3. Gaze stabilization exercises: controlled ocular and cephalic movements in immersion, targeting the vestibulo-ocular reflex. Parameters progressively increased in speed and amplitude.
4. DHI reassessment: at 2 weeks for the emotional dimension, at 4 weeks for the functional and physical dimensions. Protocol adjusted according to results.
Protocol parameter | Recommended value |
|---|---|
Session frequency | 2 to 3 times per week |
Duration per VR session | 15 to 20 minutes |
Total program duration | 4 to 6 weeks |
Assessment measures | DHI, BBS, TUG, vertigo VAS |
Interim reassessment | At 2 weeks (emotional dimension) |
Final reassessment | At 4–6 weeks (functional dimension) |
⚠️ Key point: VR habituation exercises do not replace the repositioning maneuver — they complement it. A patient whose BPPV has not been clinically resolved must not begin a habituation protocol: you risk provoking still-mobile residual crystals. Always verify the absence of positional nystagmus before initiating phase 2.
The patient profiles that benefit most from this approach
Not all post-BPPV patients require VR vestibular rehabilitation. Here are the clinical criteria that guide your decision.
Priority candidates:
Residual vertigo persisting beyond 2 to 3 weeks post-maneuver
Initial DHI ≥ 36 (moderate to severe disability)
History of recurrent BPPV (≥ 2 episodes in the past year)
Anxious profile with documented vestibular kinesiophobia
Active patient whose return to work or sport is impeded
Relative precautions and contraindications:
Unresolved BPPV (persistent nystagmus): defer phase 2
Unstabilized vestibular migraine: adapt exposure duration
Severe cybersickness: begin with static scenes, slow progression
The level of vertigo, anxiety, and depression before treatment can predict residual vertigo after successful repositioning maneuvers. Anxiety may be the strongest predictor of post-maneuver residual vertigo in elderly patients with BPPV.
This last point is clinically important: an anxious patient is one who most needs a structured approach, and VR, through its safe and titratable framework, is particularly well suited to this profile. Also consult our page on vestibular rehabilitation specific to vertigo of peripheral origin.
How KineQuantum translates this science into concrete results
From research to your daily practice.
1. Integrated vestibular protocols — KineQuantum offers habituation and gaze stabilization scenarios directly usable in session, calibrated for the residual BPPV profile. You adjust the speed of visual flows, the intensity of sensory conflict, and the duration of exposure in just a few clicks.
2. Built-in objective DHI measurement — the DHI and other clinical scales are integrated into the interface. You have longitudinal follow-up for your patients and a session report exportable for the patient file or referring physician. Full details of these features are available on the VR physiotherapy assessments page.
3. Dosed and traceable progression — each session records key parameters (duration, intensity, exercise type). You visualize your patient's progress curve and adjust the protocol in real time, just as you do with your other assessment tools.
4. Enhanced patient engagement — immersion increases effective exercise time and reduces dropout. It is possible that the longer practice duration made possible by VR contributed to the superior improvement observed in the VR group compared to the conventional group. A patient who exercises longer progresses further.
**5. A standalone or sensor-based tool depending on your context —** whether you work in a private practice or a rehabilitation center, there is a KineQuantum configuration adapted to your organization.
Conclusion: the repositioning maneuver is only the beginning of care
BPPV is often the story of a patient treated in a few minutes on the table… and yet not quite recovered. Post-maneuver residual vertigo is a clinical reality that is too often underestimated.
Virtual reality vestibular rehabilitation gives you a structured tool to address this second presentation: stimulating central neuroplasticity, desensitizing the nervous system to sensory conflicts, restoring postural confidence — and measuring everything with the DHI.
Your added value as a physiotherapist is not limited to the skill of your hands during the maneuver. It also lies in your ability to build a complete, evidence-based protocol through to the patient's genuine functional recovery.

FAQ
What is the DHI and how should it be used in physiotherapy vestibular rehabilitation?
The DHI (Dizziness Handicap Inventory) is a validated 25-item questionnaire assessing the impact of vertigo on the physical, functional, and emotional dimensions of daily life. Its score ranges from 0 (no disability) to 100 (maximum disability). In practice, you have it completed at the initial assessment and at the end of the protocol: a variation of 18 points or more is considered clinically significant and objectively documents your management.
Is virtual reality vestibular rehabilitation effective for residual vertigo after an Epley maneuver?
Yes, clinical data support VR for post-BPPV residual vertigo. A 2024 study of 124 patients showed that the group receiving VR vestibular rehabilitation achieved significantly greater reductions in DHI and VSI than the groups performing Cawthorne-Cooksey or Brandt-Daroff exercises alone. VR is therefore a relevant complement to repositioning maneuvers, not a substitute.
How many VR vestibular rehabilitation sessions are needed to improve a post-BPPV patient?
A program of 4 to 6 weeks, at a rate of 2 to 3 weekly sessions of 15 to 20 minutes, represents the reference duration in published protocols. Emotional improvement may be observed as early as 2 weeks, while functional and physical DHI improvement is generally observable at 4 weeks. Beyond this point, maintenance of gains at 8 weeks is documented in the literature.
Can virtual reality be used for vestibular rehabilitation in a private practice without heavy equipment?
Yes. Devices such as KineQuantum are designed to work in private practice, without a dedicated technical room. The standalone version requires neither a desktop computer nor complex installation. You launch a vestibular protocol in seconds from the interface. Supervision remains mandatory for patient safety, particularly in elderly individuals.
Which BPPV patients are not candidates for virtual reality vestibular rehabilitation?
Patients whose BPPV has not been clinically resolved (persistent positional nystagmus) must not begin the VR habituation phase before receiving the appropriate repositioning maneuver. Furthermore, active unstabilized vestibular migraine, severe cybersickness, or an ophthalmological contraindication constitute precautions to evaluate before the first session. For these profiles, very gradual progression using visually less stimulating scenes is recommended.
