The most frequently performed EMG tests

Carpal tunnel syndrome

Carpal tunnel syndrome (CTS) is a pressure on the median nerve

in the wrist area. It causes tingling, numbness and pain in the hands and / or fingers.

The symptoms of carpal tunnel syndrome include:

pain in the fingers, hand, or arm;

numbness of the hands at night or in the morning waking the patient up;

tingling or tingling in fingers I to III;

weakness of the thumb or difficulty grasping.

Treatment of carpal tunnel syndrome includes the use of semi-rigid scales on the forearm while you sleep.

Treatment with traditional painkillers is ineffective.

In most cases, surgery is the only effective treatment.

The neurophysiological examination of the carpal tunnel syndrome includes examination of the sensory and motor fibers of the median nerve and the ulnar nerve, and a comparative examination.

Elbow canal syndrome

Elbow canal syndrome is a condition that involves compression or stretching of the ulnar nerve in the area of the ulnar nerve sulcus (around the elbow), which can cause numbness or tingling in the ring finger (4th finger)

and small (5th finger), forearm pain and / or weakness in the hand.

The ulnar canal syndrome can cause pain, loss of sensation, tingling and / or weakness . 

The "pins and needles" are usually felt in the ring and little fingers (4th and 5th finger). These symptoms are often felt when the elbow is flexed for a long time, such as when leaning on the elbow, holding the phone or while sleeping.

The neurophysiological examination of the ulnar isthmus includes the examination of the sensory and motor fibers of the ulnar nerve and the examination of short sections of the ulnar nerve groove.


Tetany is a group of symptoms associated with excessive neuromuscular excitability resulting from a relative (latent tetany) or absolute (overt tetany) deficiency of magnesium and calcium in the serum.

Tetany can cause symptoms of paroxysmal numbness, tingling, muscle cramps, neuromuscular hyperactivity, feelings of anxiety, restlessness and palpitations.

Neurophysiological diagnosis of tetany consists in performing a tetany test consisting in tightening the cuff of the blood pressure monitor on the arm for 10 minutes, at the end of the test for 2 minutes the patient is asked to breathe regularly. In the meantime, a disposable electrode is inserted into the muscle of the hand.

After the cuff is released and breathing returns to normal, an appropriate examination is carried out with the observation of the spontaneous discharges characteristic of tetany.


Polyneuropathy (poly + neuro + -pathy) is a lesion or disease of many peripheral nerves (peripheral neuropathy) in more or less the same areas on both sides of the body, characterized by numbness, burning, or burning pain, and may be accompanied by weakness in the limbs.

Usually symptoms start in the hands and feet and may travel upward.

A variety of metabolic or inflammatory disorders can cause polyneuropathy, with diabetes being the most common cause of polyneuropathy. In some cases, it is impossible to establish the cause of polyneuropathy.

The neurophysiological examination of the polyneuropathy syndrome includes the examination of the sensory and motor fibers of 4 peripheral nerves.
