Electroneuromyography (ENMG)

Electroneuromyography (ENMG) - a complete electrophysiological study needed to determine the functional state of the peripheral nervous system and muscles.

 The electroneuromyografy examination is a diagnostic examination of nerve and muscle function.

There are 3 types of ENMG:

- Surface ENMG (performed using skin electrodes to study the passage of pulses during voluntary contraction of muscles);

- Local ENMG (retraction potentials by introducing into the muscle concentric electrodes);

- Stimulation ENMG (biopotentials abduction carried out by both cutaneous and needle electrodes in the peripheral nerve stimulation).

Features modern electroneuromyography:

Electroneuromyography opens a wide range of possibilities in the field of neuromuscular diagnostics. This technique allows you to:

• identify lesions neuro-muscular system of human;

• Determine the degree of muscle damage and peripheral nervous system;

• set the terms of the disease, its extent and the stage;

• predict the pattern of the disease;

• make a diagnosis in cases of diseases of the brain and spinal cord;

• determine the effectiveness of the treatment, to monitor the dynamics of the disease.

In addition, the possibility of giving electroneuromyography topical differential diagnosis (determination of the level of destruction)

• Conductive and central lesions;

• neuronal (spinal atrophy, syringomyelia, amyotrophic lateral sclerosis, and others.);

• segmental spinal lesion;

• abnormalities in neuromuscular transmission - synaptic damage (myasthenic syndrome, myasthenia gravis, and others.);

• neural lesions of different nature (infectious inflammation of the nerves, lesions caused by toxic or metabolic disorders, traumatic injuries).

Indications for electromyography:

• Neurological manifestations of osteochondrosis.

• Injuries to peripheral nerves, plexus.

• injuries and spinal cord injuries. Concussion.

• facial nerve neuropathy.

• Inflammatory polyneuropathy.

• Toxic polyneuropathy.

• Diabetic neuropathy.

• Polymyositis.

• Endocrine myopathy.

• Hereditary myopathy (muscular dystrophy).

• Neural amyotrophy (Charcot-Marie et al.).

• Spinal amyotrophy (Werdnig-Hoffmann et al.).

• The residual effects of polio.

• Syringomyelia.

• Amyotrophic lateral sclerosis.

•           Multiple sclerosis.

• Tunnel Syndrome.

• Myasthenia gravis, myasthenic syndrome, botulism.

• parkinsonian syndrome.

• Functional disorders of the nervous system.
