What is Tinel's sign?

Tinel's sign is a physical test that can help point out the diagnosis of the carpal tunnel syndrome. A positive sign can be caused by clicking the wrist over the area where the middle nerve is located. Patients with carpal tunnel syndrome usually experience armor and numbness in their middle fingers, forefinger and thumbs due to clicking in this area. Although having a positive tinel sign may indicate the presence of a carpal tunnel syndrome, this diagnosis is best confirmed by the conduct of the nervous guidance studies. Part of the engine and the sensory function of the hand is supplied by the middle nerve. Because the nerve must pass through a narrow opening - a carpal tunnel - in the wrist area, it can often be compressed. When the nerve is compressed in this area, the results of the carpal tunnel syndrome, the cods of symptoms, including numbness or tingling of the fingers, fingers pain, poor coordination of the muscles of the hand and the weakness of the fingers. Usually symptoms affect the middle finger, index finger and thumbs as well as halfpalms placed near the fingers.

patients complaining about the symptoms associated with the carpal tunnel syndrome are often thoroughly examined by doctors to see if they are actually affected by this condition. One of the tests of physical tests that can be performed to check the syndrome is Tinel's sign. To carry out this physical test maneuver, a doctor or other medical specialist taps the skin overlapping the carpal tunnel, located in the middle of the wrist, directly below the palm. When patients experience dullness and armor in their hand as a result of this knocking, this is considered a positive result.

Having an apositive tinel sign does not necessarily mean that the patient has a carpal tunnel syndrome, as other conditions may also cause the patient to have a positive result, such as problems causing middle nerve compression in other places. Patients with a condition called the thoracic syndrome,in which the origin of the middle nerve is compressed at the lower neck or upper arm level may also have a positive result. In general, however, the syndrome will have about three -quarters of patients with a positive test result.

Overall, Tinel's sign is not the best method for the diagnosis of carpal tunnel syndrome, since only about half of the patients suffering from the carpal tunnel tunnel will have a positive test. Further physical test tests, such as Phalen's character, can be checked. However, the confirmation test is conducted by a study of nervous lines. In this test, the needles are inserted into points along the middle nerve path and the speed at which the electrical activity is carried out by the nerve is measured. The abnormal results of the management confirm the diagnosis of the carpal tunnel syndrome.
