What is the primary purpose of vestibular rehabilitation therapy?

• A. A customized exercise program to promote central compensation, stabilize gaze, and improve balance after vestibular loss.
• B. To suppress vestibular function.
• C. To cure vestibular loss with medication.
• D. To replace vestibular function with assistive devices

Answer: (A)

The main idea is that vestibular rehabilitation therapy helps the brain compensate for reduced vestibular input through a customized set of exercises that rebuild eye movement control and balance. By engaging in targeted gaze stabilization activities, the brain learns to use other senses and adapt to head movements, improving how we stabilize our gaze (so vision stays clear when we move) and how we maintain balance during daily tasks. The program also includes habituation to movements that provoke dizziness and practice with standing and walking to build better postural control. This combination taps into the brain’s ability to reorganize and optimize sensory integration, leading to reduced dizziness and improved function over time.

It isn’t about turning down vestibular signals, which would be suppression. It isn’t about curing the underlying vestibular loss with medication. And it isn’t about replacing the lost function with devices. Instead, it focuses on training the nervous system to compensate and regain functional abilities.
