Vestibular & Dizziness Rehabilitation Services in Iredell County

Carolina Rehab provides specialized treatment options for dizziness and vertigo.

Evidence has shown that vestibular rehabilitation can be effective in improving symptoms related to many vestibular (inner ear/balance) disorders. People with vestibular disorders often experience problems with vertigo, dizziness, visual disturbance, and/or imbalance. These are the problems that rehabilitation aims to address. Other problems can also arise that are secondary to vestibular disorders, such as nausea and/or vomiting, reduced ability to focus or concentrate, and fatigue.

Why is Vestibular and Inner Ear Treatment Important?

Symptoms due to vestibular disorders can diminish the quality of life and impact all aspects of daily living. They also contribute to emotional problems such as anxiety and depression. Additionally, one of the consequences of having a vestibular disorder is that symptoms frequently cause people to adopt a sedentary lifestyle to avoid bringing on, or worsening, dizziness, and imbalance. As a result, decreased muscle strength and flexibility, increased joint stiffness, and reduced stamina can occur. Treatment strategies used in rehabilitation can also be beneficial for these secondary problems.

How Is Vestibular Rehabilitation Defined?

Vestibular rehabilitation (VR), or vestibular rehabilitation therapy (VRT) is a specialized form of therapy intended to alleviate both the primary and secondary problems caused by vestibular disorders. It is an exercise-based program primarily designed to reduce vertigo and dizziness, gaze instability, and/or imbalance and falls. For most people with a vestibular disorder, the deficit is permanent because the amount of restoration of vestibular function is very small.

However, after vestibular system damage, people can feel better and function can return through compensation. This occurs because the brain learns to use other senses (vision and somatosensory, i.e. body sense) to substitute for the deficient vestibular system. The health of particular parts of the nervous system (brainstem and cerebellum, visual, and somatosensory sensations) is important in determining the extent of recovery that can be gained through compensation.

How Does Our Body Compensate For These Symptoms?

For many, compensation occurs naturally over time, but for people whose symptoms do not reduce and who continue to have difficulty returning to daily activities, VRT can help with recovery by promoting compensation.

The goal of VRT is to use a problem-oriented approach to promote compensation. This is achieved by customizing exercises to address each person’s specific problem(s). Therefore, before an exercise program can be designed, a comprehensive clinical examination is needed to identify problems related to the vestibular disorder. Depending on the vestibular-related problem(s) identified, three principal methods of exercise can be prescribed:

Habituation
Gaze Stabilization, and/or
Balance Training

Where Does This Type of Treatment Begin?

Habituation exercises are used to treat symptoms of dizziness that are produced because of self-motion and/or produced because of visual stimuli. Habituation exercise is indicated for patients who report increased dizziness when they move around, especially when they make quick head movements, or when they change positions like when they bend over or look up to reach above their heads. Also, habituation exercise is appropriate for patients who report increased dizziness in visually stimulating environments, like shopping malls and grocery stores, when watching action movies or T.V., and/or when walking over patterned surfaces or shiny floors.

Habituation exercise is not suited for dizziness symptoms that are spontaneous and do not worsen because of head motion or visual stimuli. The goal of habituation exercise is to reduce the dizziness through repeated exposure to specific movements or visual stimuli that provoke patients’ dizziness. These exercises are designed to mildly, or at the most moderately, provoke the patients’ symptoms of dizziness. The increase in symptoms should only be temporary, and before continuing onto other exercises or tasks the symptoms should return completely to the baseline level.

Over time and with good compliance and perseverance, the intensity of the patient’s dizziness will decrease as the brain learns to ignore the abnormal signals it is receiving from the inner ear.

Utilizing Gaze Stabilization Exercises

Gaze Stabilization exercises are used to improve control of eye movements so vision can be clear during head movement. These exercises are appropriate for patients who report problems seeing clearly because their visual world appears to bounce or jump around, such as when reading or when trying to identify objects in the environment, especially when moving about.

There are two types of eye and head exercises used to promote gaze stability. The choice of which exercise(s) to use depends on the type of vestibular disorder and the extent of the disorder. One type of gaze stability exercise incorporates fixating on an object while patients repeatedly move their heads back and forth or up and down for up to a couple of minutes. The following pictures demonstrate examples of this type of gaze stability exercise.
