Electroneuromyography (ENMG)

Electroneuromyography (ENMG) is a diagnostic method used to assess the condition of peripheral nerves and muscle function. The examination is applied to detect neurological and muscular disorders, nerve injuries, and impairments in nerve impulse transmission.

When is electroneuromyography required?

In patients with muscle weakness, numbness, tingling, cramps, or pain in the limbs. It is used in the diagnosis of polyneuropathy, tunnel syndromes (including carpal tunnel syndrome), radiculopathy, and myasthenia. The method helps identify consequences of trauma, diabetic neuropathy, multiple sclerosis, and amyotrophic lateral sclerosis (ALS). ENMG is also indicated in compression syndromes and disorders of blood supply to nerve endings.

Types of electroneuromyography

• Stimulation ENMG – evaluates the speed of nerve impulse conduction and helps detect damage to peripheral nerves.
• Needle ENMG – performed with the insertion of fine needle electrodes to analyze the condition of individual muscles.
• Surface ENMG – a non-invasive examination that records muscle activity using skin electrodes.

How is the examination performed?

Electrodes are placed on the patient’s skin or needle electrodes are inserted, after which nerves and muscles are stimulated with weak electrical impulses. The procedure lasts 30–60 minutes and may require minimal preparation, such as avoiding caffeine and ensuring muscle relaxation.

Main advantages of electroneuromyography in Belarus

High diagnostic accuracy for nerve and muscle disorders. The possibility of detecting pathologies at early stages and assessing the severity of nerve damage. Safety, high informativeness, and the ability to monitor the effectiveness of treatment for neurological diseases.

Belarusian medical centers are equipped with modern electromyographs that provide detailed diagnostics of peripheral nervous system diseases. Experienced specialists perform examinations with high accuracy and professional interpretation of results.
