Is calledelectromyography(EMG) and is a medical method, which associated withelectroneurography(ENG) is used to analyze the good functionality of theperipheral nervous system.
It is very useful in various cases, to evaluate the functionality of peripheral nerves and skeletal muscles.
Electromyography: what is it for
L'electromyography(as well as electroneurography) is a clinical examination required by the specialist doctor. Generally, this assessment is required in case of:
- Strength reduction
- Sensitivity disorders (tingling, limbs falling asleep, sensations of pins in the fingers, sensations of temperature ....)
- Painful perception following a stimulus
- Pain in muscle and nerve bundles
- Reduction in the volume of one or more muscles
- Feeling that small muscle bundles are moving involuntarily (fasciculation)
- Persistent lumbosciatica
- Pain in the upper limbs
- Pain in the lower limbs
- Pain associated with the possible presence of a pathology affecting the nerve root
L'electromyographyis a diagnostic test that uses the recording of the electrical activity of muscles and nerves to obtain information about the presence of any dysfunctions.
L'electromyographyit is used in the case of disc herniation, arthrosis with osteophytosis, engagement in the conjugation foramina and neuropathies such as carpal tunnel syndrome.
Electromyography: lower limbs or upper limbs
L'electromyographyof the upper or lower limbs is performed while seated or lying on a bed. TheArtsthey are individually connected to the machine (electromyograph) with electric cables that give off a slight shock. According to the test, theelectromyographyit can be performed with contracted muscles or in resting conditions.
The duration of theelectromyographyit can range from a few minutes up to 40 minutes.
Beforedo the electromyographyit is advisable to avoid the application of lotions, ointments or body creams that could prevent or hinder the passage of electrical currents.
Is electromyography painful?
It depends on the subjective pain threshold. The jolts used for nerve stimulation are mild, however, in some cases, when testing is the muscles, small needles may be used to insert into the muscles.
L'electromyographyisloanable, however, there are waiting lists to access this exam.
How muchthe ticket costsfor theelectromyography? Pursuant to DFRV 4776 of 12/30/1997, the cost is calculated for each individual muscle or nerve identified by the doctor when prescribing the examination.
For this reason, thecost of the ticket for electromyographyit can vary from a minimum of € 46.15 (exam for 8 segments) and a maximum of € 82.30 (exam for 16 segments).
How much does electromyography costin a private center?
Thecostvaries from center to center. To answer this question we contacted several clinics scattered throughout the boot.
Thecostwho requested us forelectromyographyof the limbs (upper and lower) varies a lot from a minimum of 70 euros up to a maximum of 150 euros regardless of the number of segments! In fact, if the mutual society makes this distinction, private centers ask only what the examination is for, that is, for the diagnosis of which pathology.
Thecostofelectromyographyit can vary not only by clinic but also by who does it to you. Because in some clinics contacted, theelectromyographyit was performed by a specialized technician, in others, however, it was performed by a Neurologist expert in Neurophysiology who would also offer a brief preliminary visit.
Electromyography: why is it done?
Electromyography is done to evaluate the functionality of nerves and muscles. This test is prescribed for the diagnosis of several diseases affecting the nerves and muscles, to name a few:
- Carpal tunnel syndrome
- Diabetic polyneuropathy
- Entrapment of the Ulnar at the elbow
- Compression of the Popliteal Sciatico External to the fibular capital
- Compression syndrome of other nerve trunks
- Guillain-Barrè syndrome
- Chronic inflammatory demyelinating polyradiculoneuropathy
- In case of a traumatic injury to a nerve or nerve plexus
EMG (electromyography) allows you to ascertain the exact compression point of the nerve, once the doctor has raised a diagnostic suspicion.
In order to monitor a clinical condition already in progress, theelectromyography is donein the context of therapeutic trials or research protocols. L'electromyographyit can also be prescribed when:
- In case of a diabetic neuropathy
- In the presence of alcoholic neuropathy
- Uremic neuropathy
- Compressive radiculopathies
- Chronic pain syndromes
