PPPD in physiotherapy - understanding and rehabilitation

Rehabilitation of PPPD: identifying, understanding and treating persistent postural-perceptual vertigo

> Peripheral palsy accounts for up to 17% of consultations in specialized vertigo centers. A 2025 meta-analysis of 442 patients confirms an average improvement of 21.8 points on the DHI after vestibular rehabilitation. Here's how to establish the correct clinical framework and conduct effective management.

A patient tells you that they don't "spin" or "feel particularly dizzy," but that they feel unsteady almost constantly, especially when standing, walking, in supermarkets, or in visually demanding environments. This is often where PPPD (Post-Precipitation Disorder) comes into play. And it is precisely this picture, sometimes seemingly vague, that requires rigorous clinical interpretation to avoid therapeutic dead ends.

For a long time, these patients navigated between several specialties without a clear answer. Since the diagnostic formalization by the International Classification of Vestibular Disorders in 2017, the framework has become clearer, and the levers for rehabilitation better identified. For the physiotherapist, this is a real clinical opportunity: with the right strategy, PPPD responds well to rehabilitation, provided the right framework is established from the outset.

What is PPPD?

PPPD, or Persistent Postural-Perceptual Dizziness, is a chronic functional vestibular disorder. In French, it is generally referred to as vertigo postural-perceptual persistant. The patient describes less a spinning attack than a persistent sensation of instability, swaying, floating, or spatial disorientation.

The diagnostic framework is based on several consistent elements. Symptoms have been present for at least three months, with a high frequency, often daily. They are aggravated by standing, walking, active or passive movements, as well as by complex visual environments—busy corridors, shopping centers, traffic, screens, contrasting patterns.

Far from being marginal, this disorder is now recognized as the leading cause of chronic vertigo in some specialized centers. Epidemiological data published in 2025 indicate that PPPD represents approximately 14% of vertigo consultations in internal medicine and up to 17% in specialized vertigo and balance clinics [1].

The key point for the clinician is that PPPD is neither "imaginary," nor purely psychiatric, nor reducible to a simple lack of vestibular compensation. It is a real disorder of sensory integration and postural control, often maintained by strategies of hypervigilance and overcontrol.

Why the PPPD is causing confusion in consultations

PPPD frequently challenges conventional reasoning. The otoneurological assessment may be normal or unremarkable. Symptoms are significant, but objective signs are sometimes subtle. The patient may have already consulted several professionals, experiencing a sense of incomprehension that impairs adherence to treatment and reinforces avoidance.

In practice, the problem also stems from the fact that PPPD often appears after a clearly identified triggering event and then persists even after the initial cause has subsided. This event could be vestibular neuritis, BPPV, a vestibular migraine, a concussion, an episode of acute anxiety, or even a period of major stress. The alarm system remains activated even though the initial threat is no longer the same.

> ⚠️ Key point: in PPPD, treating the initial trigger is not enough. It is the self-perpetuating nature of the disorder, characterized by hypervigilance and postural overcontrol, that becomes the main therapeutic target.

For the physiotherapist, this changes the strategy. Treating it solely as a classic case of peripheral vestibular hypofunction risks only partial improvement. Reassuring the patient without providing explanations can sometimes perpetuate avoidance. And introducing symptoms too quickly, without structure or guidance, can worsen the condition and lose the patient's trust.

Clinical mechanisms to keep in mind

PPPD readily develops in an environment of maladaptive sensory recalibration. The patient begins to overuse visual and proximal somatosensory information, while becoming less tolerant of movement and postural uncertainty. Posture becomes stiffer and less automatic. Gait loses fluidity. Attention becomes fixated on internal sensations which, through constant monitoring, gain in perceived intensity.

This feedback loop is familiar to practitioners who treat balance and vestibular disorders . The more a patient tries to voluntarily control their stability, the less efficiently their postural system functions. The more they avoid triggering situations, the lower their tolerance threshold becomes. PPPD is therefore not just a disorder of symptoms—it is also a disorder of the relationship to movement, the visual environment, and sensory prediction.

> 💡 Key takeaway: PPPD addresses three self-perpetuating factors — visual overuse, postural rigidity, and attentional hypervigilance. Effective rehabilitation works on these three factors simultaneously, not just the symptoms.

PPPD and differential diagnosis

Before establishing a rehabilitation framework, it is necessary to rule out anything that does not constitute an isolated case of PPPD (Post-Disordered Psychosis). This is particularly important when the complaint is long-standing or multifaceted.

What you shouldn't miss

• Uncompensated unilateral or bilateral vestibular hypofunction

• An active vestibular migraine

• Persistent or recurrent BPPV

• A central neurological cause (further investigation to be conducted in consultation with a medical colleague)

• Orthostatic hypotension

• Some adverse drug effects (psychotropic drugs, antiepileptics)

• A gait disturbance of another origin

PPPD can also coexist with an objectively detectable vestibular pathology. It is not always one or the other.

Useful clues for the exam

• Chronic and fluctuating nature of symptoms (≥ 3 months)

• Marked aggravation in complex visual environments

• Significant discomfort when standing and walking

• Relative discrepancy between perceived intensity and objective anomalies

• The story of an initial triggering factor, sometimes resolved

• Stiffening strategy, excessive eye control, hesitation in postural transitions

• The perception of movement is more pronounced than the actual loss of balance.

Observing motor behavior provides a great deal of information. More than the isolated measurement of amplitude or speed, it is the overall quality of motor engagement that guides the diagnosis.

Rehabilitation of the PPPD in physiotherapy

Effective management rarely relies on a single approach. PPPD responds best to a combined, progressive approach that is clearly explained to the patient. The goal is not simply to reduce symptoms, but to restore a more automatic, confident, and less attentionally demanding movement pattern.

The evidence for efficacy is now robust. A meta-analysis published in Frontiers in Neurology in 2025, aggregating data from 442 patients with PPPD, showed an average improvement of 21.8 points on the total Dizziness Handicap Inventory (DHI) after vestibular rehabilitation, with significant gains in all three domains: physical (+17.9 points), emotional (+10.5 points), and functional (+15.0 points) [2]. A second meta-analysis in 2025 confirmed these results and highlighted the value of a multidisciplinary approach combining vestibular physiotherapy, cognitive-behavioral therapy, and, if necessary, medication [1].

Start by explaining, without minimizing

Therapeutic education is a fully-fledged intervention. The patient must understand that their sensations are real, frequent in this clinical setting, and linked to an overactive balance system. This step is crucial in reducing the fear of "missing something serious."

The way you phrase things matters. Telling a patient that there's "nothing wrong" is often counterproductive. It's better to explain that there's a persistent functional disorder affecting sensory and postural processing, which rehabilitation can address. This approach is reassuring without trivializing the problem.

Re-expose the system to movement

Vestibular rehabilitation remains essential, but requires careful judicious use. Exercises in eye stabilization, movement habituation, and postural control are beneficial, provided they are calibrated to avoid immediate failure. In PPPD (Postural Repetitive Behavior Therapy), the progression must be sufficiently stimulating to induce adaptation, without being so intense as to reinforce anticipatory anxiety.

It is often helpful to start with simple tasks and then gradually add visual complexity, dual tasks, variations in support, and movement in space. The implicit message sent to the patient is crucial—their system can tolerate this and then learn again.

Reintegrate the vision without becoming dependent on it

The visual environment is central to the problem for many patients with PPPD. The goal is not to eliminate vision, but to modulate its role in the balance strategy. Therefore, working with sensory conflicts , moving backgrounds, visually dense scenes, or walking in stimulating environments makes sense.

This is where immersive tools can provide real clinical value when used correctly. The first randomized study of vestibular rehabilitation with virtual reality applied to PPPD showed a significant improvement in symptoms, quality of life, and gait function, particularly marked in patients with severe visual vertigo [3]. VR allows for precise control of visual load, safe reproduction of triggering situations, and monitoring of reproducible progress—all elements difficult to achieve in a traditional clinical setting.

Working on motor confidence

In these patients, recovery is not measured solely by the reduction of symptoms. It is also evident in the quality of movement. A smoother gait, better tolerated head rotations, less anticipated changes of direction, a resumption of activities avoided for months – these are very telling clinical indicators.

Kinesiophobia isn't always explicitly stated as such, but it's often present. The patient avoids shops, public transport, open spaces, and sometimes even extended walks. Reintroducing movement to areas where the brain anticipates danger is a central part of the treatment.

What makes the difference in the results

Not all PPPDs progress at the same rate. Some improve rapidly once the diagnosis is made and explained. Others require more extensive work, particularly in cases of comorbid anxiety, associated vestibular migraine, or a history of treatment failure.

Pacing matters more than sheer intensity. Overly cautious exposure can stall progress, while overly aggressive exposure undermines engagement. In practice, the best results often occur when the patient understands the purpose of the exercises, tolerates a moderate level of symptoms during the session, and then finds that they recover safely.

The interdisciplinary approach is also important. Depending on the case, an ENT, neurological, or specialist medical opinion may be necessary. For some patients, structured psychological support can be a catalyst, not because the disorder is inherently "psychological," but because the mechanisms of anticipation and hypervigilance directly perpetuate the complaint.

Objectification through reproducible assessments also plays an often underestimated role. Being able to show the patient their measured progress—perceptual biases, performance in balance tests, tolerated rotation speed—changes the dynamics of care. The patient is no longer solely responsible for judging their sensations; they have external reference points.

How KineQuantum transforms this science into concrete results

KineQuantum was designed with and for physiotherapists who treat complex vestibular patients, including those with PPPD. The goal is not to replace your reasoning, but to provide you with concrete tools to apply recommendations from the literature.

From research to your daily practice:

1. A measured and reproducible visual exposure : animated corridors, dense scenes, moving backgrounds, environments with high optical flow — all very useful contexts in PPPD that VR allows you to calibrate precisely, session after session. You remain in control of the progression.

2. Integrated objective vestibular assessments : perception of vertical and horizontal, balance course with eyes open or closed, speed and continuity of rotations. The measurements are automatically recorded and used to show progress to the patient and the referring physician.

3. A library of exercises aligned with EBP (Evidence-Based Practice) : eye stabilization, movement habituation, dual task, postural transitions, walking in complex environments. All recommended areas of functional vestibular rehabilitation are available.

4. A session-compatible integration : 10 to 20 minutes of immersive exercise can be inserted into a regular session without any major reorganization. You can then follow up with manual work, reinforcement, or educational advice.

5. A format adapted to your practice : KineQuantum Liberté (self-contained, all-in-one headset, quickly deployable) or KineQuantum Classique (with external sensors for finer measurements in assessment).

The tool does not make a diagnosis, nor does it determine the dose or progression. It provides you with a safe and measurable clinical environment to implement your chosen strategy, particularly regarding the visual lever, which is central to PPPD.

Towards a more precise and engaging PPPD rehabilitation

The PPPD (Patient-Centered Postural Rehabilitation) approach requires moving beyond standard responses. It demands diagnostic precision, educational skills, carefully measured exposure, and a functional view of recovery. When the patient begins to move again without monitoring every sensation, you know that rehabilitation is progressing well.

Clinical evidence is now sufficient to offer structured and effective treatment. Provided that the right framework is established from the outset, exposure is rigorously controlled, and the patient's motor confidence is supported, PPPD is an excellent platform for the application of vestibular physiotherapy expertise.

FAQ — PPPD Rehabilitation

Is PPPD a psychological disorder? No. PPPD is a functional vestibular disorder recognized by the International Classification of Vestibular Disorders since 2017. It involves a genuine disruption of sensory integration and postural control. Anxiety may be present and should be considered, but the disorder itself is neurofunctional, not psychiatric.

How many physiotherapy sessions are needed to treat PPPD? This depends on the duration of the condition, any comorbidities, and the initial severity. Published protocols generally last 8 to 12 weeks, with 1 to 2 sessions per week. The first improvements often appear after 4 to 6 sessions once the diagnosis is made and clearly explained.

Is a complete vestibular assessment necessary before rehabilitation? Yes. Before planning rehabilitation, it is essential to rule out uncompensated vestibular hypofunction, BPPV, active vestibular migraine, or a central cause. A joint otoneurological assessment with an ENT specialist is the standard, supplemented by your own functional evaluation.

What is the benefit of virtual reality specifically for PPPD? VR allows for the reproduction of complex visual environments—supermarkets, crowds, moving patterns—which are precisely the triggering contexts for PPPD, but difficult to recreate in a clinical setting. It offers precise dosing, reproducible progression, and safe exposure. A randomized study published in Scientific Reports confirmed its efficacy, particularly pronounced in patients with severe visual vertigo [3].

Can the patient's PPPD worsen with the exercises? A transient exacerbation of symptoms during a session is common and is not a sign of worsening. It is the lack of recovery between sessions, or a marked increase in avoidance, that should raise concern and lead to dose adjustment. The rate of progression is more important than the raw intensity.
