Dizziness is one of the most common symptoms of neurological origin. Of all types of dizziness, the most common is benign positional vertigo, which is detected in more than 80% of all patients who complain.
This type of dizziness is associated with pathology of the inner ear and vestibular apparatus. Usually this type of dizziness occurs suddenly, the patient cannot indicate the specific reason that provoked the development of an attack of instability. Although during the examination, attention is drawn to the formation of instability as a result of sudden movements of the patient’s head or body, after which an attack is formed. This type of dizziness has a paroxysmal character due to its short duration, i.e. This condition is characterized by a rapid increase in symptoms and an equally rapid disappearance.
Essence and basic principles
The Epley maneuver or exercises are a special maneuver used to treat benign paroxysmal positional vertigo (BPPV).
This procedure is often carried out in a physiotherapy office, but it can also be done at home after a specialist shows all the basics of the technique. This maneuver was developed by Dr. John Epley, after whom it was named. The first time it was talked about was back in the 80s of the last century.
The Epley maneuver is a series of exercises that help relieve symptoms of dizziness. Numerous studies have proven that this technique is the simplest, safest and most effective in the treatment of dizziness caused by the deposition of calcium salts in the inner canal of the ear.
All these exercises do not eliminate the presence of otoliths, but only change their location. Such manipulations cause them to move to other areas of the inner ear that do not cause dizziness.
The essence of the technique is to place your head at an angle at which gravity helps relieve unpleasant symptoms. Tilt of the head helps remove crystals from the semicircular ear canals. This means that they stop displacing fluid, which is what causes nausea and dizziness in a person.
As a result, it turns out that this maneuver relieves all symptoms, but you need to do the set of exercises several times. The thing is that the first time the crystals can move a small distance.
It is worth remembering that the Epley maneuver requires special concentration from a person, all actions must be precise, no sudden movements.
There are a number of rules that must be followed:
- classes should take place in a well-lit room;
- there should not be any objects with sharp corners, carpet paths, or objects that could cause a person to fall near the patient;
- It is better to perform the exercise on a soft surface; a couch, yoga mat, or thick-pile carpet are suitable for this;
- the clothes a person wears should be loose, not restricting movements, so that he can move easily and freely;
- shoes on feet should be without heels;
- while performing exercises, someone must be present next to the person; it is unknown how his body will react to the exercise; someone needs to provide backup;
- if a person feels unwell or has symptoms of other diseases, then therapy is postponed until the person feels better;
- Even after the Epley maneuver is successfully performed, when the results sought are obtained, you will need to visit the doctor several more times to prevent a relapse.
Experts who recommend the Epley maneuver to their patients for symptoms such as dizziness note that after the first use of a set of exercises, serious changes are observed. The symptoms go away, but only if you follow all the prescribed recommendations for several days after them.
Diagnostics
The main method for diagnosing BPPV is to evaluate the results of positional tests, during which successive turns and tilts of the head are performed, which leads to the displacement of free otoliths, nystagmus appears and an attack of dizziness may occur. The most common test for diagnosing BPPV is the Dix-Hallpike test. The test is considered positive if the doctor detects a certain type of nystagmus. For each semicircular canal, its own diagnostic tests have been developed.
In typical cases, there are no difficulties in diagnosing BPPV, since nystagmus has strict specificity when performing positional maneuvers. If positional nystagmus and vertigo do not fall within the parameters expected with positional tests, and the disease is not treatable with positional maneuvers, a central origin of vertigo should be suspected and additional examination methods should be prescribed.
Differential diagnosis
Central vestibular disorders affecting the cerebellum and brain stem (stroke, transient ischemic attack, multiple sclerosis, tumors).
Vestibular migraine is usually accompanied by headache.
Vestibular neuronitis is a lesion of the vestibular ganglion, presumably of inflammatory origin. It manifests itself as an acute episode of dizziness, accompanied by a balance disorder with intact hearing.
Meniere's disease is a disease of the inner ear, manifested by a triad of symptoms: systemic dizziness, sensorineural hearing loss, and subjective ear noise.
Indications for use
The Epley maneuver is prescribed by a doctor only after examination, examination and an accurate diagnosis. It is also worth remembering that these exercises can only be recommended for stable, non-progressive illness.
Among these pathologies:
- period after a stroke;
- benign positional paroxysmal vertigo;
- violation of movement coordination;
- osteochondrosis;
- recovery period after injury to the spine or brain;
- ear diseases;
- infectious pathologies.
Gymnastics does not affect muscle function in any way. Its main goal is to teach a person to control attention, so regular use does not cause any unwanted manifestations.
Tablets for vestibular vertigo
Drugs for vestibular vertigo are Betaserc, Betagistin, Tagista, Vestibo, as well as drugs that support the endocrine system, the heart, and reduce blood pressure. Betaserc improves blood circulation in the brain and promotes the functioning of the vestibular apparatus. Betahistine is often used in complex treatment; it helps with nausea and vomiting. Tagista improves blood circulation in the brain and reduces lymph pressure in the labyrinth of the inner ear. A stable effect is achieved after a month of treatment. Vestibo improves blood circulation in the inner ear and brain; the drug is used in complex therapy.
Contraindications for use
The Epley maneuver for dizziness is a safe therapeutic procedure, but it does have a number of contraindications.
It is prohibited to carry out manipulations if the patient:
- with active manifestations of symptoms: confusion, disorientation;
- respiratory function is impaired if there are problems with the functioning of the heart, blood vessels, and respiratory organs;
- worsening after exercise.
In other cases, the maneuver can be carried out, but it is better to do this under the supervision of a specialist.
Useful tips for patients
There are some recommendations that will help you complete the procedure successfully with maximum results and without any inconvenience:
- Before starting the exercises, the specialist recommends that the patient take a vestibulolytic drug. It will help reduce the severity of symptoms. Take dimenhydrinate in a dosage of 100 mg half an hour before the start of the procedure.
Take 2 Dramamine tablets 30 minutes before the Epley maneuver for dizziness. - All exercises should be performed quickly, but without sudden movements.
- When performing the maneuver, the neck should be extended as much as possible, thereby protecting against re-entry of calcium salts into the semicircular canal.
- The patient may need to perform the maneuver several times in 1 session.
The mechanism of pathology development
In order to understand the mechanism of development of dizziness, you should know the structure of the system responsible for the problem. The inner ear contains receptors involved in maintaining balance:
- auditory;
- vestibular (elliptical and spherical pouch + 3 semicircular canals).
Receptor susceptibility to acceleration:
- semicircular canals - to the angular one;
- bags - to linear.
Important! Pouch receptors consist of a mucopolysaccharide gel with fibers and small crystals - otoliths.
Under the influence of various reasons, the receptors disintegrate, releasing otoliths, which subsequently enter the fluid of the semicircular canals. Head movements provoke otolithic movement, which is the cause of the rotational sensations typical of vertigo.
Main complex
Back in the early 80s of the last century, a set of exercises was developed, which today is called the Epley maneuver.
Its use allows calcium carbonate crystals to move out of the semicircular tubules under the influence of gravity. During this maneuver, the patient often experiences an increase in autonomic symptoms, which can be explained by the fact that otolith fragments are forced to move.
It is better to perform the maneuver for the first time only in the presence of a specialist. Its main feature is a clear trajectory, slow movement from one position to another, without any sudden movements.
The Epley maneuver for dizziness requires precise adherence to all exercise techniques:
- The patient sits straight on the couch, turns his head towards the ear (45˚), in which an accumulation of otoliths is detected.
- Without turning your head, you need to lie down on the couch with your head thrown back slightly. You need to stay in this position for at least 1 minute.
- Turn your head 90˚ towards your healthy ear and hold for 30 seconds.
- The body and head in a fixed position are turned in the same direction by another 90˚. The patient's face at this moment should be directed downward. Stops again for 30 seconds.
- Again the person returns to the starting position, sitting on the couch.
While performing the maneuver, the person should feel slightly dizzy. If such a symptom appears, it means that he is doing everything correctly. All the exercises described above should be performed several times for 10 minutes. Only in this case can the full effect be achieved.
The Epley maneuver for dizziness does not accept any sudden movements; all manipulations must be smooth. After exercise, you should definitely rest. Regular exercise will allow you to gradually dissolve all the salts and forget about dizziness.
If after the first session of the Epley maneuver there are no results or the patient experiences frequent relapses, then in this case a modified procedure can be used at home. If you follow all the rules for doing the exercises, the symptoms disappear after a few days.
The Epley maneuver can also be used as a diagnostic tool in people who cannot be definitively diagnosed with BPPV but are strongly suspected to have it. But it is carried out only if the Hallpike tests are negative.
Exercises for vestibular vertigo
Dizziness often occurs when turning the head or body - this forces patients to try to avoid such movements. Gymnastics for patients with vestibular system disorders includes various types of exercises, including exercises with head and body turns. Exercises can be performed while sitting on a bed, with or without a pillow, sitting on a chair, or standing. The exercises are based on the principle of sensory mismatch between the movements of the eyes, torso and head. Special simulators that work on the principle of biofeedback will help increase the effectiveness of gymnastics. During the training period, you should avoid taking sedatives and alcohol.
Consolidate the result
After exercise, you need to sit for 10 minutes. This is necessary to ensure that all the contents of the inner ear remain in place and do not move. This is the only way to protect yourself from repeated attacks of dizziness. You should wear a soft pillow around your neck for the rest of the day. With its help, you can limit head movements and record the results of the Epley maneuver for a long time.
In the days following the exercises, you need to sleep with your shoulders and head straightened. It is better to sleep in a position where your head is turned 45˚. During the day, after the Epley maneuver, the head should be kept upright. You should not visit a hairdresser or dentist at this time, who will ask you to tilt your head back.
You should not perform exercises that require sudden movements and throwing your head back.
After the Epley maneuver, you should wait a week and not provoke attacks of dizziness during this period. Check to see if symptoms appear if you take a position that previously caused them. If there is no recurrence of symptoms, then the procedure was successful.
Drug treatment
There are no drugs that have a direct effect on canal/cupolothiasis.
Drug treatment is advisable only for frequent attacks or during maneuvers.
Drugs are used that reduce the excitability of the vestibular system, both selectively and through a general sedative effect. The first include drugs with a vestibulolytic effect - blockers of H1 and H3 histamine receptors, cinnarizine, atarax, first generation antihistamines - diphenhydramine, pipolfen.
Evidence has been obtained in favor of reducing the intensity of dizziness when performing the Epley maneuver simultaneously with taking betahistine 24 mg x 2 times a day for a week.
Sedatives, most commonly benzodiazepine tranquilizers (diazepam), are used in hospital settings for the symptomatic treatment of severe recurrent attacks.
When to expect an effect
After the first session, within 3 days, and after a month, the patient is recommended to visit a specialist. If symptoms do not go away, you may need to repeat the maneuver or need to look for other causes and remedies to get rid of dizziness.
Relapses occur in 20 patients out of 100.
The Epley maneuver may not produce the desired results if:
- neck extension is insufficient, due to which calcium salts return to their place;
- the patient has blockage of the posterior semicircular canal with a conglomerate;
- the diagnosis was incorrectly made and the patient does not have canalolithiasis of the posterior semicircular canal, but cupulolithiasis, as a result of which, after performing the maneuver, the pressure goes in the opposite direction;
- transformation of BPPV of the posterior canal into BPPV of the anterior canal.
The table below shows other types of vestibular maneuvers that can be used if the Epley maneuver does not give the desired result. But they are used only on the recommendation of a doctor.
Maneuver name | Peculiarities |
Semonta | It is carried out only under the supervision of medical personnel. Often during it, patients experience a pronounced autonomic reaction, manifested in the form of nausea, vomiting and heart rhythm disturbances. It is carried out like this: sitting on the couch, legs hanging, the patient turns his head towards the healthy ear. The head in this position must be fixed with the help of hands. The patient in this position moves to a lying position on the side of the sore ear. Stay for a couple of minutes, relax. Afterwards, the patient quickly sits down again, the head remains fixed, and turns over to the other side. Head down, lie down again for 2 minutes, and then return to the starting position. |
Lempert | This maneuver is very similar in technique to the Epley maneuver. The difference is that after turning the patient’s torso on its side, with the healthy ear down, the rotation of the torso continues. The patient lies on his stomach face down, and then on the sore eye with his ear down. At the end of the complex, he returns to a sitting position. Its actions strongly resemble rotation around its axis. After performing this maneuver, you should avoid bending your body for several days and sleep only on a raised head of the bed or on a hard pillow. |
In rare cases, relapses may occur or the complex needs to be repeated, but after talking with the patient it turns out that he did not adhere to the recommendations. The maneuver is truly an excellent opportunity to remove otoliths from the inner ear, because they are the ones that cause an unpleasant symptom, but a favorable result is guaranteed only if all the rules are followed.
The Epley maneuver is an effective complex that helps a person get rid of dizziness without any harm to health.
Thanks to this technique, it is possible to normalize the vestibular apparatus if the problems are associated with the deposition of calcium salts in the inner ear. But it should only be carried out on the recommendation of a doctor, there is no self-medication and it is better to do everything the first time in the presence of a specialist.
