Electromyoneurography (EMNG)

Electromyoneurography (EMNG) is an electrodiagnostic method that examines the electrical activity of muscles and nerves with the ability to determine the level, degree and extent of the lesion. It can quickly and quickly confirm a clinical diagnosis or even diagnose diseases and injuries of the peripheral nervous system, some diseases and injuries of the brain’s nerves (such as nervus facialis), and also exploration of the anal and urethral sphincter, in diseases and injuries of the spinal cord sacral roots that pervadal nerves inervish the mentioned sphincter.

In clinical practice, pre-administration of EMNG requires a pre-detailed clinical and neurological examination, and if necessary, some of the neuroradiological tests (radiography, magnetic resonance, scanner, etc.).

Electromyography (EMG) and Electroneurography (ENG) – EMNG is a very important complementary method in clinical testing of the nervous system, and is a sovereign method in virtually all neuromuscular diseases. It is applied as:

Detective electromyography (EMG) – examination of electrical activity of muscles

Stimulation electromyography, or electroneurography (ENG) – measurement of peripheral nerve conduction velocity – (with the possibility of some reflexological tests such as H-reflex, Blink reflex, F-wave, and others).

INDICATIONS FOR EMNG:

Different neuromuscular diseases (neuropathies)

Chronic diseases, metabolic diseases (eg diabetic polyneuropathy)

The following diseases (eg congenital anatomy of the bone-joint system)

Compression of the nerves (discus hernias)

Spinal and limb injuries

Some rheumatic diseases of the type of muscle inflammation (myositis)

Post-operative conditions or conditions after spinal cord and brain disease

Various other injuries with muscle and peripheral nerves

Sphincteral weaknesses due to illness (spina bifida)

In childhood, due to later maturation of the central nervous system (brain), EMNG examination was also indicated in some tone disorders, slow motor development, vague weaknesses of the hands and feet, various injuries and congenital anomalies.

In addition to being a diagnostic neurophysiological method, EMNG is also a prognostic method, on the basis of which can monitor the course of the disease and recovery of the patient, and predict the outcome of the disease or injuries.

WHAT DOES THE EMNG LOOK LIKE?

– The review is done without narcotic treatment and it is not painful if there is cooperation with the patient. It takes 30 to 45 minutes and can be more or less unpleasant. The test is performed on technologically highly computerized apparatus, whereby the conductivity of peripheral nerves, motor and / or sensitivity is usually first examined. This test is performed mostly by percutaneous electrodes (through the skin), while for muscle testing, sterile needle electrodes are always used as a rule. The number of examined nerves and muscles depends on clinical diagnosis.

The examination is done in all ages, and for children (from birth). If a patient is a child, it is desirable to have one parent present.
