Nerve conduction study

Description nerve conduction studies

Nerve conduction study (INP) – тест, which measures the speed and force of the electrical signals in the nerve. The test helps to gather information about the structure and functions as a muscle, and nerves.

Совместно с исследованием нервной проводимости часто проводится электромиография (DOH).

Reasons for the study of nerve conduction

Study of nerve conduction is most commonly carried out for the following purposes:

• Help diagnose the cause of pain, seizures, numbness or weakness;
• Determine malfunctioning nerves;
• Find muscle and nerve disorders;
• Check the condition of the nerve after injury and recovery.

How is nerve conduction studies?

Preparation for the procedure

In the run-up to the procedure:

• Tell your doctor about taking any medications;
• In the presence of myasthenia ask your doctor, what medicines you need to take before the test;
• We need to avoid cigarettes, coffee, tea and soft drinks during the 2-3 hours prior to the study;
• On the day of the test you need to take a shower. Do not apply skin creams, moisturizers, cosmetics;
• Wear comfortable clothes.

Procedure nerve conduction studies

The skin will be cleaned with a special solution. By the skin at the site of passage of the studied nerve will be attached electrodes. The doctor with the help of electric current will stimulate the nerves, to increase their activity. Using electrodes measured current, passing along the nerve. If the nerve is damaged, current will flow slowly and poorly. The physician will use stimulation in different locations, to determine the specific location of nerve damage.

After a nerve conduction study

After completing the test, you will be able to return to their daily activities.

How long will the study of nerve conduction?

About 30-90 minutes.

Will it hurt the study of nerve conduction?

You will feel mild discomfort from the application of an electric current stimulation. The procedure does not cause pain.

Results of the study of nerve conduction

The doctor will analyze the test data. The results will be available within a few days.

Contact your doctor after nerve conduction studies

Call a doctor, if you have any questions or problems after study.
