Why Abstract Patterns Alone Are Insufficient

Canvas-driven optokinetic patterns are valuable for early-stage desensitization — but they do not replicate the visual complexity patients encounter in daily life.

Abstract patterns

Stripes and dots desensitize the motion pathway but lack ecological validity. Patients improve in the clinic but remain symptomatic in supermarkets and busy streets.

In-vivo exposure

Taking patients to real environments is effective but logistically difficult, unpredictable, and impossible to grade systematically.

YouTube videos

Real-world footage exists online, but without clinical overlays, graded difficulty, or session tracking. No fixation targets, no dimming control, no outcome data.

Avoidance behavior

Without structured exposure, patients avoid triggering environments. Avoidance reinforces visual dependence and delays functional recovery.

Visual vertigo is context-specific. Effective habituation requires graded exposure to the visual environments that provoke symptoms — not just abstract motion stimuli.

How Video Training Works

Three steps to context-specific visual vertigo habituation

1

Choose a Video Environment

Select from 7 real-world environments graded by visual complexity — from a quiet library to a busy casino floor. Each environment targets different aspects of visual motion processing.

2

Configure Clinical Overlays

Add a fixation target for gaze anchoring, enable gaze guidance arrows for directed visual scanning, or apply screen dimming to reduce stimulus intensity for sensitive patients.

3

Grade Exposure with Progression

Start with simple environments, high dimming, and fixation ON. Progress to complex scenes with no overlays as tolerance improves. Record pre/post symptoms to track habituation.

7 Real-World Environments Graded by Complexity

Each environment targets different aspects of visual motion processing — from slow, predictable movement to fast, chaotic optic flow

Simple

Library

Slow camera movement through quiet shelving aisles. Minimal optic flow, predictable depth planes. Ideal starting environment for highly sensitive patients.

Simple

Escalator

Ascending and descending views with linear optic flow. Controlled motion in one axis. Addresses elevator and escalator avoidance specifically.

Intermediate

Store

Walking through retail aisles with moderate visual clutter. Shelving parallax, overhead lighting, and periodic signage create mid-level visual complexity.

Intermediate

Street

Urban sidewalk perspective with pedestrians, vehicles, and building facades. Multi-speed optic flow across depth planes challenges visual-vestibular integration.

Intermediate

Transit Station

Platform and corridor views with crowds, signage, and trains. Combines crowd flow, overhead information displays, and intermittent fast-moving objects.

Advanced

Market / Grocery

Busy market environment with dense product displays, moving shoppers, and fluorescent lighting. High visual clutter across all depth planes. Targets supermarket syndrome directly.

Advanced

Casino / Complex Indoor

Maximum visual complexity — flashing lights, patterned carpets, moving displays, crowds. The most challenging environment for visual vertigo patients.

Clinical Overlays for Guided Visual Processing

Three overlay types give clinicians precise control over the patient's visual processing during video exposure

Fixation Target

A static or subtly pulsing dot at screen center provides a gaze anchor. Patients maintain fixation while peripheral visual motion occurs around it. Reduces symptom provocation in early exposure phases by constraining foveal attention.

Use for: Initial exposure, highly sensitive patients, establishing gaze stability before removing support

Gaze Guidance

Directional arrows or highlighted zones guide the patient's visual scanning pattern. Structures how the patient engages with the visual scene rather than allowing avoidant gaze patterns.

Use for: Training active visual scanning, addressing avoidant gaze behavior, transitioning from fixation to free viewing

Screen Dimming

Reduces overall stimulus intensity by applying a semi-transparent overlay. Adjustable from 10% to 80% dimming. Lowers the effective contrast and brightness of the video without changing content.

Use for: Photosensitive patients, migraine-associated visual vertigo, reducing initial stimulus intensity while maintaining scene content

Graded Exposure: From Controlled to Complex

A four-phase protocol for systematic visual vertigo habituation using video environments

1

Phase 1: Anchored Viewing

Library or Escalator Fixation ON, high dimming (60-80%) 30 seconds

Patient views simple environment with fixation target and heavy dimming. Establishes baseline tolerance with minimal symptom provocation.

2

Phase 2: Guided Exploration

Store or Street Fixation ON, moderate dimming (30-50%) 60 seconds

Increase environmental complexity while maintaining fixation support. Dimming reduced as tolerance builds.

3

Phase 3: Active Scanning

Market or Transit Gaze guidance ON, no dimming 90 seconds

Shift from passive fixation to active guided scanning in complex environments. Gaze guidance structures visual exploration without constraining it.

4

Phase 4: Free Viewing

Casino or complex scene No overlays Full duration (2-3 minutes)

Patient views the most challenging environments without any clinical support. Free viewing replicates real-world conditions and confirms habituation.

Progression criteria: advance when symptom provocation during the current phase stays below 2/10 increase for three consecutive sessions. If symptoms exceed 4/10 increase, step back one phase.

Evidence for Video-Based Visual Vertigo Habituation

The approach draws on established research in visual vertigo, optokinetic stimulation, and graded exposure for vestibular disorders

Pavlou M, et al. (2004, 2012)

Visual vertigo habituation with optokinetic stimulation

Supervised optokinetic exercise with graded visual stimuli significantly reduces visual vertigo symptoms. The 2012 follow-up demonstrated that combining optokinetic stimulation with customized vestibular rehabilitation outperformed generic protocols.

Bronstein AM (2004)

Vision and vertigo: clinical aspects of visual-vestibular interaction

Visual dependence — over-reliance on visual input for balance — is a core mechanism in visual vertigo. Systematic visual motion exposure reduces dependence over time through habituation.

Staab JP, et al. (2017)

Diagnostic criteria for persistent postural-perceptual dizziness (PPPD)

PPPD is characterized by chronic dizziness worsened by visual stimulation and complex environments. Graded exposure to provocative visual stimuli is a recommended therapeutic approach.

Whitney SL, et al. (2016)

Virtual reality and vestibular rehabilitation

Immersive visual environments can deliver controlled vestibular challenges that complement traditional rehabilitation. Video-based approaches provide similar graded exposure without VR equipment costs.

Clinical Applications

Visual Vertigo

Direct habituation to the visual environments that provoke symptoms. Supermarket aisles, busy streets, and transit stations — each matched to the patient's specific triggers.

PPPD

Persistent postural-perceptual dizziness responds to graded visual exposure. Video environments allow systematic progression from simple to complex without leaving the clinic.

Vestibular Migraine

Visual motion sensitivity in vestibular migraine benefits from controlled exposure. Screen dimming and fixation targets manage photosensitivity during habituation.

Post-Concussion Visual Sensitivity

Many concussion patients report worsened symptoms in visually busy environments. Graded video exposure bridges the gap between clinic-based exercises and real-world tolerance.

Supermarket Syndrome

Dizziness triggered specifically by supermarket environments — fluorescent lighting, dense aisles, moving shoppers. The market environment targets this pattern directly.

Unilateral Vestibular Loss

Patients with compensated UVL often retain visual dependence. Video-based visual motion exposure helps reduce residual visual-vestibular reliance during functional recovery.

When to Use Canvas Patterns vs Real-World Videos

Both modes serve distinct clinical purposes. Using them together provides the most comprehensive visual vertigo rehabilitation program.

Canvas Patterns (Projector Mode)

  • Abstract optokinetic stimuli (stripes, dots, checkerboards)
  • Precise control of speed, density, direction, contrast
  • Targets the optokinetic reflex pathway in isolation
  • Ideal for early-stage desensitization and OKN training

Real-World Videos

  • Ecologically valid visual environments (stores, streets, transit)
  • Clinical overlays for fixation, gaze guidance, dimming
  • Targets context-specific visual vertigo and avoidance behavior
  • Ideal for mid-to-late stage habituation and functional transfer

Use canvas patterns to build foundational tolerance, then transition to video environments for context-specific habituation. Both modes are included in the Pro Portal subscription.

Frequently Asked Questions

Common questions about real-world video vestibular rehabilitation

What is real-world video vestibular rehabilitation?
It is a clinical approach that uses video footage of real-world environments — supermarkets, streets, transit stations — as visual stimuli for graded exposure therapy in patients with visual vertigo, PPPD, and other vestibular conditions characterized by visual motion sensitivity. Clinical overlays (fixation targets, gaze guidance, screen dimming) allow clinicians to control the exposure intensity.
How do video environments help with visual vertigo?
Visual vertigo is provoked by specific real-world contexts — busy stores, scrolling screens, crowded streets. Video environments replicate these contexts in a controlled clinical setting. By grading exposure from simple to complex environments, and from supported (fixation + dimming) to unsupported viewing, patients habituate to the visual patterns that trigger their symptoms.
What are clinical overlays and why do they matter?
Clinical overlays are visual aids layered on top of the video: a fixation target provides a gaze anchor, gaze guidance arrows direct visual scanning patterns, and screen dimming reduces stimulus intensity. They allow clinicians to control how much visual challenge the patient receives, enabling precise grading of exposure difficulty.
Can I use my own videos?
The current library includes 7 curated environments graded by visual complexity. Custom video upload is on the roadmap. In the meantime, the included environments cover the most clinically relevant scenarios for visual vertigo habituation.
How is this different from showing YouTube videos?
YouTube videos lack clinical overlays (fixation, gaze guidance, dimming), have no graded difficulty system, provide no session tracking or symptom logging, and cannot be integrated with patient records. Video environments in the Pro Portal are specifically curated and graded for vestibular rehabilitation, with full clinical control and outcome documentation.
What equipment do I need?
A laptop with a modern browser and any projector or external display. The same setup used for canvas pattern projector mode works for video environments. Larger screens provide a more immersive visual field, which enhances the habituation effect.
Is there evidence for video-based visual vertigo habituation?
The approach is grounded in established research on optokinetic stimulation (Pavlou 2004, 2012), visual dependence mechanisms (Bronstein 2004), PPPD treatment protocols (Staab 2017), and VR-based vestibular rehabilitation parallels (Whitney 2016). Video environments apply these principles using ecologically valid visual stimuli.
How do I progress patients through difficulty levels?
Follow the four-phase graded exposure protocol: start with simple environments (library) with fixation and high dimming, progress to intermediate environments (store, street) with moderate support, advance to complex environments (market, transit) with gaze guidance only, and finally move to maximum complexity (casino) with no overlays. Advance when symptom provocation stays below 2/10 increase for three consecutive sessions.
Does this integrate with the projector pattern mode?
Yes. Both canvas patterns and video environments are accessed through the same Pro Portal projector mode interface. You can use canvas patterns for early-stage OKN desensitization and transition to video environments for context-specific habituation — all within the same clinical workflow with shared session logging and outcome tracking.
How much does it cost?
Video environments are included in the Pro Portal subscription at no additional cost. The same subscription that provides canvas pattern projector mode, patient management, and session logging includes full access to all video environments and clinical overlays.
