Vertigo Cure
Vertigo is a specific type of dizziness characterized by a sensation of spinning or movement, even when a person is stationary.
StabilityLAB can help almost anyone who is experiencing vertigo, including vertigo from concussion.
With our comprehensive computerized vestibular retraining therapy, or CVRT, most people will experience relief from vertigo.
We aim to provide people with the efficacy and
benefits of CVRT in addressing vertigo
symptoms, offering individuals a path towards
improved balance and quality of life.
Standard dizziness therapies are ineffective in ⅔ of people.
StabilityLAB has developed a new AI driven technology to restore
balance function in dizziness caused by concussions, injuries, and
aging. Our solutions solve complexity challenges in stability and fall
prevention to enable mass adoption of data driven balance therapy.
What is the Vestibular System and Vertigo
The vestibular system is a collection of structures in your inner ear that regulates your sense of balance and awareness of your orientation in space. It allows you to coordinate your body movements. The vestibular system can be impacted by a concussion, contributing to symptoms such as dizziness and vertigo, as well as trouble with balance, posture, and/or vision.
Vertigo is a specific type of dizziness characterized by a sensation of spinning or movement, even when a person is stationary. It is often described as a feeling of dizziness, lightheadedness, or imbalance. Vertigo can be caused by various factors, including problems in the inner ear, head injuries, migraines, and disorders affecting the brain or nervous system.
Withdrawal from activities of daily living, exercise, and social interaction, which is common for those with deficits in postural stability, often leads to poorer physical health, cognitive decline, and emotional sequelae. Computerized vestibular retraining is associated with improved participant reported disability and objective measures of postural stability.

What is CVRT?
Vestibular rehabilitation is a form of physical therapy used to treat vestibular disorders or symptoms. Exercises are designed to reduce or eliminate issues affecting overall stability and daily function.
One newer approach to vestibular rehabilitation is computerized dynamic posturography–assisted vestibular retraining, or “computerized vestibular retraining therapy” (CVRT) for short. This is a non-invasive technique that uses interactive technology to support balance retraining.
The technology measures how your sensory systems are helping you stay upright in different conditions. Training exercises become more challenging as you move through treatment to improve your overall stability.
Who is a Candidate
for CVRT Vertigo
Treatment?
Vertigo, or persistent vertigo stemming from a concussion, unilateral vestibular weakness, bilateral vestibular weakness, meniere's disease, vestibular migraine, PPPD -persistent postural-perceptual dizziness, Mal de Debarquement syndrome, vestibular paroxysmia, bilateral vestibulopathy, presbyvestibulopathy, or motion sickness.
Early studies have shown CVRT is beneficial to vertigo treatment.
Decreased risk of falling
Increased stability
Improved balance
confidence
Reduced impact of dizziness
on daily life
5% Decreased risk of
dementia
27% Decreased risk
of all-cause death
Longevity and strength come from the power of stability.
To avoid injury, Stability is the key ingredient.
Stability is how efficiently and safely forces can be transmitted through our bodies.

The Diagnostic Battery for Concussion Treatment
Objective tests of balance function will determine the type of therapy required
Based on the pattern of intake test results, a comprehensive and personalized multi-modal computerized vestibular retraining treatment plan (the DaVID Concussion Protocol) is delivered over twelve 40 minute sessions.
Written reports summarizing pre/post vertigo treatment objective metrics are provided for all products.
VOG (Video-Oculogram)
Objective measurement of inner ear/eye reflex coordination. vestibulo-ocular reflex (VOR)
VNG (Videonystagmogram)
Gold standard objective measurement of inner ear balance function using warm and/or cool water irrigation, called Caloric Testing
cVEMP (Cervical Vestibular Evoked Myogenic Potential)
Objective measurement of inner ear gravity sensor function
oVEMP (Ocular vestibular evoked myogenic potential)
Objective measurement of inner ear gravity sensor function
Hearing Test With Middle Ear Pressure And Reflex Testing
Hearing test with middle ear pressure testing
COG (Center of gravity measurement)
Objective measurement of stability
LOS (Limits of stability measurement
Objective assessment of limits of stability before falling
SOT (Sensory organization test)
Computerized Dynamic Posturography, an objective measure of global balance function
SR (Sensory ratio)
Analysis of CDP responses which can determine relative weighting of vision, joint position sense (somatosensory), and inner ear contributions to overall stability
How does a vertigo treatment work?
CVRT has been clinically proven to reduce disability in 85% of all dizzy patients. Greater than 90% of moderate to severely imbalanced patients experienced improvement by 3-5x the clinically meaningful margin.
Initial Assessment and
First Training Session
90 Minutes
Intake and consent forms
Three questionnaires to evaluate:
- The impact of dizziness on your daily life
- Your confidence in your balance
- Your concerns about falling
Two tests to measure:
- Your balance
- Your risk of falls and your center of
gravity
Your first training session.
Training Sessions
40 minutes each
These sessions are typically scheduled twice a week and involve the following
- A technician will lead you through training exercises that progress in difficulty over the course of 12 sessions total.
- During training, you will use a machine with a safety harness, interactive surround display, and moveable platform. You will need to shift your weight forward, backward, right, and left in response to visual targets on the screen. The moveable platform you are standing on will respond to and track your movements.
- The exercises you do at each session will vary, and the visual targets on screen will become more challenging.
Final Assessment and Last Training Sessionz
90 Minutes
In your final visit you will complete your last training session and complete a final consultation with our doctor that includes:
- A review of findings from your treatment
- Completion of the same tests and questionnaires from the first session.
Risks and Complications For Vertigo Treatment
While CVRT is generally considered safe and effective, there are some potential risks associated with this therapy.
Fatigue
Performing repetitive exercises during CVRT sessions may lead to fatigue, particularly in individuals who have limited stamina or other health conditions.
Nausea or Motion Sickness
The nature of CVRT exercises, which involve visual and/or vestibular stimulation, can trigger symptoms of nausea or motion sickness in some individuals, which are typically mild and transient.
Frequently asked questions
CVRT is a clinically proven treatment for:
- Concussions
- Dizziness
- Falls
- Dementia
You will be contacted by Dr. David’s office to book the initial assessment, and a staff member there will provide additional details about how to prepare and what to expect. As a rule, plan to wear comfortable clothing and comfortable (flat) shoes at each session.
Yes, CVRT has been clinically proven to reduce disability in 85% of all dizzy patients. Greater than 90% of moderate to severely imbalanced patients experienced improvement by 3-5x the clinically meaningful margin.
The number of treatment sessions for CVRT is 12, resulting in 2 sessions per week for 6 weeks.
Each treatment session typically lasts 40 to 45 minutes.
