Sensitivity to motion in visually busy environments.
You're walking through the grocery store when suddenly, the shelves seem to move. The fluorescent lights overhead feel overwhelming. Other shoppers passing by trigger waves of dizziness. Your heart races as you grip your cart for stability, wondering if you'll make it to checkout without feeling like you might faint.
Or perhaps you're watching a movie with your family when an action scene—cars racing, cameras panning—triggers such intense dizziness that you have to leave the room. Driving on the highway has become terrifying as passing traffic makes you feel like your car is veering off the road.
If busy visual environments trigger dizziness, imbalance, or nausea, you may be experiencing Visual Vertigo (also called visual motion sensitivity or visually induced dizziness)—a condition where your brain has developed an overreliance on visual input for balance, leading to debilitating symptoms in everyday situations.
The encouraging news? Vestibular rehabilitation therapy has proven highly effective for visual vertigo and motion sensitivity, with 75% of patients showing statistically significant improvement [Moaty et al., 2017]. Even better, many patients achieve complete symptom relief, allowing them to return to activities they've been avoiding for months or even years.
At Vaughan Physiotherapy Clinic, we specialize in evidence-based vestibular rehabilitation designed specifically to retrain your brain's sensory processing—helping you overcome visual dependency and regain confidence in visually complex environments.
Visual vertigo (also called visual motion sensitivity or visually induced dizziness) is a condition where dizziness, imbalance, or nausea is triggered by busy visual environments or moving visual stimuli [Bronstein et al., 2013].
Definition and Mechanism: Visual vertigo is primarily defined as an inappropriate response to motion of the visual environment caused by an overreliance or misinterpretation of visual cues [Bronstein et al., 2013].
The Paradox:
Why It Happens: The condition occurs because the brain over-relies on visual input for balance. This overreliance, known as visual dependency or increased responsiveness to visual stimuli, often develops as a compensatory mechanism following a sensory disturbance [Bronstein et al., 2013].
Visual vertigo frequently develops after a vestibular insult. The underlying causes that lead to this visual dependency include [Bronstein et al., 2013; Thompson et al., 2015; Alves et al., 2019]:
Vestibular Disorders:
Migraine:
Concussion/Traumatic Brain Injury:
The symptoms can become a major, disabling issue as the sufferer becomes dependent on potentially misleading nonvestibular sensory stimuli [Bronstein et al., 2013].
Think of it this way: After a vestibular injury, your brain's balance "GPS" becomes unreliable. To compensate, your brain starts relying more heavily on visual landmarks for orientation. But visual information in busy environments is constantly changing and moving—so your brain is essentially trying to navigate using landmarks that keep shifting, leading to constant feelings of motion and instability.
Patients with visual vertigo frequently report that their dizziness and imbalance are triggered or worsened by moving visual surroundings [Bronstein et al., 2013].
Common Provocative Stimuli:
The Experience:While the trigger is visual, the symptom experienced is typically vestibular in nature:
Visual vertigo is closely related to the symptoms of Persistent Postural-Perceptual Dizziness (PPPD), a long-term vestibular condition (lasting more than three months) [Thompson et al., 2015].
PPPD Characteristics:
PPPD shares key physical symptoms with phobic postural vertigo, specifically:
Symptom Prevalence in PPPD Patients: In a study of individuals treated for PPPD, participants reported sensitivity to [Thompson et al., 2015]:
The broader sequelae of vestibular dysfunction may include [Bronstein et al., 2013]:
Visual vertigo often occurs alongside motion sickness symptoms, which are characterized by [Bronstein et al., 2013]:
Primary Symptoms:
Additional Symptoms:
Important: The characteristic stimulus for motion sickness in vehicles is oscillation at approximately 0.2 Hz, but visual motion alone can also provoke symptoms [Bronstein et al., 2013].
A 9-year-old child with a 9-month history presented with [Alves et al., 2019]:
This case beautifully illustrates how visual vertigo affects daily life across multiple contexts.

More Likely Visual Vertigo Syndrome:
Balance is maintained through the complex integration of three major sensory systems [Bronstein et al., 2013]:
When vestibular input is reduced or misprocessed (after concussion, neuritis, or migraine), the brain overcompensates with an overreliance on environmental visual cues, leading to visual dependency [Bronstein et al., 2013].
Why This Happens:Following a sensory disturbance (like a vestibular lesion), the brain seeks alternative sensory inputs for orientation. A disordered vestibular system causes the sufferer to become dependent on potentially misleading, nonvestibular sensory stimuli [Bronstein et al., 2013].
The Problem:This increased responsiveness to visual stimuli is referred to as visual dependency [Bronstein et al., 2013]. When this occurs:
Typical Triggers:Conditions that commonly lead to this development include [Bronstein et al., 2013]:
Fundamental Mechanism:Visual vertigo is fundamentally an inappropriate response to the motion of the visual environment.
Vestibular Disturbance and Overreliance:
After Vestibular Insult:Symptoms frequently develop after a vestibular insult:
Other Vestibular Contexts:
PPPD (which includes visual vertigo as a core symptom) typically has a triggering event:
Acute or Episodic Vestibular Disorders:
Non-Vestibular Triggers:
Generally Accepted Cause:Sensory conflict or sensory mismatch—a mismatch between actual versus expected patterns of vestibular, visual, and kinesthetic inputs.
Specific Conflicts:
Evolutionary Theory:Motion sickness may have evolved from a system designed to protect against neurotoxin ingestion by inducing vomiting when unexpected CNS inputs are detected—then activated by modern transport methods causing sensory mismatch.

Physiotherapy, specifically in the form of Vestibular Rehabilitation (VR) or Vestibular and Balance Rehabilitation Therapy (VBRT), is essential for treating conditions like visual vertigo and PPPD because it directly targets the core mechanisms of these conditions, leading to functional improvement and symptom reduction.
Multiple studies demonstrate the effectiveness of VR for visual vertigo and motion sensitivity:
Key Finding:75% of subjects showed statistically significant improvement in situational characteristic questionnaires after receiving rehabilitation.
In a pilot study evaluating VBRT for PPPD:
Of those helped by VBRT:
Vestibular rehabilitation has been shown to improve patient quality of life, allowing them to return to daily living activities with fewer symptoms.
Pediatric Success Example:A 9-year-old patient with motion sensitivity:
This success has been demonstrated even in pediatric patients, showing the broad applicability of VR.
Physiotherapy is essential because it employs techniques designed to correct the brain's inappropriate sensory processing and hyperreactivity—the root cause of visual vertigo [Bronstein et al., 2013].
The Core Therapy:The core therapy for visual vertigo is progressive desensitization (also called habituation) within a cognitive framework of reassurance and explanation.
For PPPD:
Specific measures are introduced in the rehabilitation program to:
VR involves customized exercise programs that actively retrain the nervous system [Bronstein et al., 2013; Thompson et al., 2015; Alves et al., 2019]:
Progressive Exposure to Optokinetic Stimuli:
Progression:
Purpose:Repeated exposure to provocative stimuli to achieve reduction in dizziness symptoms.
Examples:
Focus:Improving gaze stability and diminishing symptoms.
Benefit:While primarily for gaze stabilization, the primary benefit for PPPD patients may be habituating them to head motion.
Modern Physical Therapy:
Physical therapy provides a structured and progressive method to overcome the brain's overreliance on potentially misleading visual cues.
By repeatedly exposing the patient to the very stimuli that trigger symptoms, the brain learns to filter and correctly integrate sensory information—much like training a miscalibrated compass (the brain) to stop relying solely on a flickering light (visual input) and instead trust its internal mechanisms, leading to a steady, reliable sense of direction.
While the progression of untreated visual vertigo and PPPD can be chronic, the prognosis regarding recovery timelines is positive when specialized interventions like vestibular rehabilitation are utilized [Bronstein et al., 2013; Thompson et al., 2015; Moaty et al., 2017; Alves et al., 2019].
