FAQ

On this page, we have compiled a list of frequently asked questions to help you better understand what CVRT entails, who can benefit from it, its safety and effectiveness, and much more.

What is Computerized Vestibular Retraining Therapy (CVRT)?

CVRT is a specialized form of vestibular rehabilitation therapy that utilizes computer-based tools and exercises to help individuals overcome balance and dizziness issues caused by vestibular disorders.

How does CVRT work?

CVRT works by stimulating the vestibular system through a series of exercises and activities designed to promote adaptation and compensation for vestibular dysfunction. It typically involves visual and/or auditory stimuli presented on a computer screen, which the patient interacts with to improve their balance and reduce symptoms. Our data demonstrates improvement in brain balance and stability centers. CVRT is designed to drive neuroplasticity of the vestibular pathways.

Who can benefit from CVRT?

Individuals with vestibular disorders or conditions affecting balance and stability, such as vestibular neuritis, labyrinthitis, Meniere’s disease, or post-concussion syndrome, have been shown to benefit from CVRT.  Symptoms of imbalance after concussion have been shown to benefit.  Individuals with age associated vestibular loss, called Presbyvestibulopathy, experience improved stability and decreased fall risk.

Is CVRT safe?

Yes, CVRT is generally considered safe when performed under the guidance of a trained healthcare professional, such as a physical therapist or an audiologist. However, as with any form of therapy, there may be some risks involved, especially if not conducted properly or if the exercises are too strenuous for the individual.

How long does CVRT treatment typically last?

The duration of CVRT treatment varies depending on the severity of the vestibular disorder, the individual’s response to therapy, and other factors. Some patients may see improvements within a few sessions, while others may require weeks or months of treatment to achieve significant benefits.

Are there any side effects associated with CVRT?

Side effects of CVRT are generally minimal and may include temporary dizziness, nausea, or fatigue, particularly during the initial stages of therapy as the brain adjusts to the exercises. However, these symptoms typically subside as treatment progresses.

Can CVRT be done at home?

While some CVRT exercises may be performed at home under the guidance of a healthcare professional, it is generally recommended to undergo therapy in a clinical setting initially to ensure proper assessment and supervision. Additionally, specialized equipment and software may be required for certain CVRT exercises, which may not be available for home use.

What should I expect during a CVRT session?

During a CVRT session, you can expect to undergo a series of exercises and activities tailored to your specific needs and symptoms. These may include tasks such as eye movements, head movements, balance exercises, and visual stimulation on a computer screen. Your therapist will guide you through each exercise and monitor your progress throughout the session.
