Vestibular gymnastics. How to deal with dizziness


Eye tracking

Sit in a comfortable position, take in your hand a small (the size of a postcard or map) thick piece of paper with a few words printed on it in regular font. Hold a piece of paper 30 cm away at eye level. Move the piece of paper horizontally to the right and left. Repeat the exercises, moving the sheet vertically, then diagonally. During the exercise, the head should remain motionless; you need to follow the leaf only with your eyes. Over time, move the piece of paper faster and faster until you can no longer make out the words written on it.

In each plane you need to repeat the exercise 15–20 times.

Rules for performing vestibular gymnastics

  • Vestibular gymnastics should be done daily, 2 times a day.
  • The duration of the lesson should be 20–30 minutes, after which rest is necessary.
  • Standing exercises should be performed barefoot or in comfortable shoes without heels.
  • During vestibular gymnastics, you should not rush, so as not to fall.
  • You should not exercise if you are feeling unwell due to another illness (for example, a cold or migraine).
  • To evaluate the results and adjust the exercise program, you must contact your doctor every two weeks (by phone or in person).

Patient M., 53 years old, was admitted to the emergency department of a city hospital with complaints of dizziness with a sensation of rotation of surrounding objects, aggravated by movement, nausea and vomiting. Due to dizziness, the patient was unable to walk without support. Dizziness appeared 3 hours ago. The day before there was an episode of short-term (within a few seconds) dizziness with slight nausea, which regressed on its own. A week before the onset of dizziness, he suffered from acute respiratory viral infection.

During examination in the hospital emergency department, horizontal nystagmus directed to the left was noted. In the Romberg test, the patient deviated to the right. There were no other focal neurological symptoms. The dizziness continued for about 5 hours, gradually weakening. However, due to instability and nausea worsening with movement, he was almost unable to walk; I took a few steps only with support. Over the next two weeks, the condition gradually improved: attacks of systemic dizziness did not recur, instability occurred only with sudden movements and quickly getting out of bed. The occurrence of acute vestibular dizziness in a patient who suffered from acute respiratory viral infection a few days ago, the absence of focal neurological symptoms with the exception of horizontal nystagmus and vestibular ataxia, the course of the disease in the form of gradually (within several hours) decreasing dizziness and vestibular ataxia, persisting for several weeks and also gradually regressing, allowed us to diagnose vestibular neuronitis in the patient. What are the tactics for treating vestibular neuronitis in the acute period, what should be the rehabilitation, and what is the likelihood of relapse? The clinical picture of vestibular neuronitis was first described by Eric Ruttin in 1909 and then in more detail by Carl Nielen in 1924. The term vestibular neuronitis was coined by Charles Hallpike in 1949. Vestibular neuronitis is the third most common cause of acute vestibular vertigo after benign paroxysmal positional vertigo and Meniere's disease. The disease predominantly occurs between the ages of 30 and 60; men and women are affected equally often. Etiology and pathogenesis The etiology and pathogenesis of vestibular neuronitis are not completely clear. The disease is associated with selective inflammation (viral or infectious-allergic origin) of the vestibular nerve, as indicated by the results of a few pathomorphological studies. Viral etiology (most often herpes simplex virus type 1) of vestibular neuronitis is supported by the frequent development of the disease after a respiratory viral infection, the epidemic nature of the disease with a peak incidence occurring in late spring and early summer, as well as cases of simultaneous illness of several members described in the literature. families. The role of the herpes virus is confirmed by cases of the development of herpetic encephalitis with vestibular neuronitis. Vestibular neuronitis usually affects the superior branch of the vestibular nerve, which innervates the horizontal and anterior semicircular canals, as well as the elliptical sac of the labyrinth vestibule, as indicated by the frequent combination of vestibular neuronitis with benign paroxysmal positional vertigo, which is usually caused by otolithiasis of the posterior semicircular canal, innervated by the inferior branch of the vestibular nerve . Damage to the inferior branch of the vestibular nerve is much less common. Clinical presentation and diagnosis Vestibular neuronitis manifests itself as a sudden and prolonged attack of systemic dizziness, accompanied by nausea, vomiting and imbalance. The disease may be preceded by a respiratory viral infection. Sometimes, several hours or days before the development of an acute vestibular attack, patients experience brief episodes of dizziness or unsteadiness. Symptoms of vestibular neuronitis increase with head movements or changes in body position. Dizziness may improve with fixed gaze. Spontaneous nystagmus is characteristic, the fast phase of which is directed towards the healthy ear. The imaginary rotation of objects around the patient is also typically directed towards the healthy ear. In the Romberg test, the patient deviates towards the affected ear. Hearing does not decrease. Neurological examination shows no symptoms of damage to the brainstem or other parts of the brain. The duration of dizziness ranges from several hours to several days. Spontaneous nystagmus persists for 3–5 days, nystagmus when the eyes are moved towards the healthy ear in Frenzel glasses (that is, when gaze fixation is turned off) is observed for another 2–3 weeks. After the dizziness stops, patients continue to experience instability for several days or weeks. The timing of restoration of vestibular function depends on the degree of damage to the vestibular nerve, the rate of central vestibular compensation and the patient’s performance of vestibular gymnastics. In many patients, rapid head movements can cause oscillopsia and mild short-term instability for a long time after vestibular neuronitis. According to Okinaka et al., one year after the disease, vestibular function was completely restored in 40% of patients, partially in 20–30% of patients, and in other cases, unilateral vestibular areflexia remained. However, even in the absence or incomplete recovery of vestibular function, patients usually do not experience significant changes in daily activities due to vestibular compensation. In many patients who have suffered vestibular neuronitis, complaints of dizziness reflect an existing somatoform disorder. Vestibular neuronitis rarely (in 2% of cases) recurs; when the disease recurs, the “healthy” vestibular nerve is affected. If a patient who has been diagnosed with vestibular neuronitis has repeated attacks of vestibular vertigo, then other causes of vertigo should be looked for, among which the most common are Meniere's disease, benign paroxysmal positional vertigo and vestibular migraine. The diagnosis of vestibular neuronitis is based on the clinical picture of the disease: acute and relatively long-term (from several hours to several days) vestibular dizziness, accompanied by instability, horizontal or horizontal-rotatory spontaneous nystagmus with oscillopsia, nausea and vomiting. The diagnosis can be confirmed using a caloric test, which reveals vestibular hypo- or areflexia on the affected side. In a rare lesion of the inferior branch of the vestibular nerve, the caloric test is negative, but vestibular neuronitis is confirmed by changes in vestibular evoked potentials. Indirect signs of vestibular neuronitis can be detected using high-resolution magnetic resonance imaging (MRI) of the brain with gadolinium. Differential diagnosis is carried out with other conditions manifested by prolonged vestibular vertigo. Unlike vestibular neuronitis, acute labyrinthitis often occurs against the background of a systemic infection or acute otitis media and is accompanied by hearing loss. Perilymphatic fistula usually occurs after cranial trauma, barotrauma, severe coughing or straining, and is accompanied by hearing loss, confirmed by a fistula test. A stroke in the vertebrobasilar system is accompanied by other focal neurological disorders, central nystagmus, and brain damage according to MRI. Vestibular neuronitis is often difficult to distinguish from the first attack of Meniere's disease, which is more likely if the dizziness is accompanied by tinnitus, a feeling of fullness in the ear, and hearing loss. Treatment Treatment is aimed at reducing dizziness, nausea and vomiting (symptomatic treatment) and accelerating vestibular compensation. Symptomatic treatment includes the use of drugs belonging to the group of vestibular suppressants. The drug of choice is dimenhydrinate at a dose of 50–100 mg every 6 hours. Instead of dimenhydrinate, metoclopramide, benzodiazepine tranquilizers and phenothiazines can be used. For vomiting, use the parenteral route of administration (diazepam IM, metoclopramide IM, thiethylperazine IM or rectally in suppositories). The duration of use of vestibular suppressants is determined by the duration and severity of dizziness; they are generally not used for more than three days because these drugs slow down vestibular compensation. To speed up the restoration of vestibular function, vestibular gymnastics is recommended, which includes exercises in which movements of the eyes, head and torso lead to sensory mismatch. These exercises stimulate central vestibular compensation. However, performing them at first can be associated with significant discomfort. The tactics of vestibular rehabilitation and the nature of the exercises depend on the stage of the disease, which reflects the contents of Table 1. In patients with vestibular neuronitis, the use of methylprednisolone in the first three days of the disease (in an initial dose of 100 mg, followed by a dose reduction of 20 mg every three days) leads to a higher the frequency of restoration of vestibular function one year after the disease. Despite the presumably viral nature of the disease, the use of antiherpetic drugs in patients (alone or in combination with methylprednisolone) does not improve the recovery process. To accelerate vestibular compensation, in combination with vestibular gymnastics, you can use betahistine dihydrochloride (Betaserc 24 mg) 48 mg per day (1 tablet 24 mg 2 times a day). This drug, by blocking NS receptors of the central nervous system, increases the release of neurotransmitters from the nerve endings of the presynaptic membrane (histamine prevents the release of neurotransmitters), having an inhibitory effect on the vestibular nuclei of the brain stem. Experimental studies have shown that betahistine accelerates vestibular compensation. In an animal experiment, Betaserc had a dose-dependent effect on the electrical activity of polysynaptic neurons in the vestibular nuclei. References 1. Albera R., Ciuffolotti R., Di Cicco M. et al.
