    Vestibular Rehabilitation

    Vertigo, Inner Ear Pathology, Decreased Balance

Vestibular rehabilitation (VR), also known as vestibular rehabilitation therapy (VRT), is a specialized form of physical therapy used to treat vestibular disorders or symptoms, characterized by dizziness, vertigo, and trouble with balance, posture, and vision. These primary symptoms can result in secondary symptoms such as nausea, fatigue, and lack of concentration. All symptoms of vestibular dysfunction can significantly decrease quality of life, introducing mental-emotional issues such as anxiety and depression, and greatly impair an individual, causing them to become more sedentary. Decreased mobility results in weaker muscles, less flexible joints, and worsened stamina, as well as decreased social and occupational activity. Vestibular rehabilitation therapy can be used in conjunction with cognitive behavioral therapy in order to reduce anxiety and depression resulting from an individual's change in lifestyle.

Vestibular disorders

The term "vestibular" refers to the inner ear system with its fluid-filled canals that allow for balance and spatial orientation. Some common vestibular disorders include vestibular neuritis, Ménière's disease, and nerve compression. Vestibular dysfunction can exist unilaterally, affecting only one side of the body, or bilaterally, affecting both sides.

Diagnostic tests

Vestibular disorders can be diagnosed using several different kinds of assessments, some of which include examination of an individual's ability to maintain posture, balance, and head position. Some diagnostic tests are more easily performed in a clinical setting than others but relay less specific information to the tester, and vice versa. A proper history of symptoms should include what those symptoms are, how often they occur, and under what circumstances, including whether the symptoms are triggered or spontaneous.

Other conditions that can be treated with vestibular rehabilitation therapy are symptoms of concussions and dizziness in patients with multiple sclerosis. Magnetic resonance imaging techniques can be used as diagnostic tools to determine the presence of issues that can be treated with vestibular rehabilitation, regardless of whether they are vestibular in nature.

Non-vestibular dizziness

In some cases, the results of vestibular tests are normal, yet the patient experiences vestibular symptoms, especially balance issues and dangerous falls. Some diagnoses that result in non-vestibular dizziness are concussions, Parkinson's disease, cerebellar ataxia, normal-pressure hydrocephalus, leukoaraiosis, progressive supranuclear palsy, and large-fiber peripheral neuropathy. There are also several disorders known as chronic situation-related dizziness disorders. For example, phobic postural vertigo (PPV) occurs when an individual with obsessive-compulsive characteristics experiences a sense of imbalance, despite the absence of balance issues. Chronic subjective dizziness (CSD) is a similar condition characterized by persistent vertigo, hypersensitivity to motion stimuli, and difficulty with precise visual tasks. Both phobic postural vertigo and chronic subjective dizziness may be treated with vestibular rehabilitation therapy or other therapeutic methods such as cognitive behavioral therapy and conditioning.

Rehabilitation exercises

Vestibular rehabilitation is specific to the dysfunction that a patient experiences. Some treatment methods seek to eliminate the cause of vestibular dysfunction, while others allow the brain to compensate for dysfunction without targeting the source. The former goal is for treating benign paroxysmal positional vertigo, while the latter treats vestibular hypofunction, which cannot be cured. The treatment process should begin as early as possible, to decrease fall risk. The patient should start slowly, gradually increasing the intensity and duration of exercises, and be accompanied by an accessible and reassuring therapist, as discomfort and negative emotional states can negatively affect treatment.

Treatment of benign paroxysmal positional vertigo

Treatment of benign paroxysmal positional vertigo (BPPV) depends on the canals involved (horizontal or vertical) and which form of BPPV the patient is experiencing (canalithiasis versus cupulolithiasis). Canalithiasis is characterized by a dislodged otolith particle, called otoconia, that floats in the fluid in one of the three vestibular canals and cause the feeling of dizziness with vision disturbances. On the other hand, cupulolithiasis is another form of BPPV caused by an attachment of otolith particle in the cupula (the base of semicircular canal) of the involved canal.

Canalith repositioning treatments

Canalith repositioning treatments (CRT) aim to move debris in the inner ear out of the semicircular canal in order to treat benign paroxysmal positional vertigo. CRT has 5 key elements:

  1. Premedication of the patient
  2. Specific positions
  3. Timing of shifts between positions
  4. Use of vibration
  5. Post-maneuver instructions

Early attempts to treat BPPV involved similar processes that were believed to be habituation exercises, but more likely dislodged and dissolved debris.

Treatment of vestibular hypofunction

Vestibular hypofunction can be a unilateral or bilateral vestibular loss. There are three types of vestibular rehabilitation exercises to reduce symptoms in cases where physical dysfunction cannot be reduced. The category of exercises chosen by a vestibular therapist depends on the problems reported by the patient. The following exercises can be used to treat dizziness with fast movements or exposure to intense visual stimuli, difficulty seeing (appearance of bouncing or jumping visual field) with head movement, and trouble with balance.


Habituation exercise aims to repeatedly expose patients to stimuli that provoke dizziness, such as certain motions and harsh visual stimuli. The provoking stimulus will induce dizziness at first, but with continued habituation exercises, the brain can adapt to discount the stimulus and dizziness reduces. As this occurs, the exercises can increase in intensity. The patient should take breaks between exercises when symptoms are experienced, until the symptoms stop.

Gaze stabilization

Gaze stabilization exercises aim to increase visual ability during head movement. The goal of the patient during these exercises is to maintain the gaze during head movement. One kind of gaze stabilization exercise involves looking at a target and moving the head back and forth, without looking away from the target. Another exercise requires looking from one target to another, first without moving the head, and then moving the head to be aligned with the target without shifting the eyes. The last exercise for gaze stabilization is known as the remembered-target exercise and is performed partially with the eyes closed. First, the patient looks at a target object directly in front of them. Next, the patient closes their eyes and turns their head and turns it back. When the patient opens their eyes, they should still be looking at the target object.

Balance training

Balance-training exercises (also known as postural-stabilization exercises) are designed to improve a patient's ability to stay upright, and reduce the likelihood of dangerous falls. Balance-training exercises can be done walking or standing and can incorporate head movements and habituation exercises to limit exacerbation of symptoms. Increased postural stability can be achieved using visual and somatosensory cues. Thus, exercises in this category challenge the body's use of these cues by limiting or changing them. For example, having the patient close their eyes limits their ability to rely on visual cues to maintain postural stability, while having the patient stand on foam alters their reliance on somatosensory signals.


Research has shown that, overall, 80 to 85 percent of patients with chronic vestibular disability reported a reduction in symptoms after VR.

There is evidence that vestibular rehabilitation therapy increases the "balance, quality of life, and functional capacity" of patients with multiple sclerosis.

In a study of 109 children, an association between completion of vestibular rehabilitation and improvement of concussion symptoms and visuovestibular performance was found. A different study found that vestibular and physical therapy were linked to a shorter recovery period, resulting in a more rapid return to sports.
