What is Tinel's sign used for?
Tinel's sign is a way to detect irritated nerves. It is performed by lightly tapping (percussing) over the nerve to elicit a sensation of tingling or pins and needles in the distribution of the nerve. It takes its name from French neurologist Jules Tinel (1879–1952).
Is Tinel’s sign painful?
A true Tinel’s sign may be uncomfortable for the patient, but it is never painful. Another test called the Phalen test to diagnose carpal tunnel syndrome involves bending your wrist at a 90 degree angle for one minute may cause symptoms of numbness, tingling, or weakness to appear in your hand.
What does pure Tinel sign mean?
Pure Tinel sign means that that the lesion is in anatomic continuity and sequential recordings can demonstrate progression of recovery. Roots C 5 and C 6 are the most superficial and Tinel sign can easily be elicited. C 7, C 8 and T 1 are deeper and difficult to assess.
How do you perform a tinel sign?
It is performed by lightly tapping (percussing) over the nerve to elicit a sensation of tingling or "pins and needles" in the distribution of the nerve. The Tinel sign is the tingling or prickling sensation elicited by the percussion of an injured nerve trunk at or distal to the site of the lesion. The sign also indicates nerve regeneration.
What does positive tinel's sign mean?
A positive Tinel sign means that tapping your nerve causes a tingling sensation to radiate through that area of your body. It's sometimes described as a pins and needles feeling. The Tinel sign shows there's damage in the nerve.

How does tinel's sign work?
Tinel sign is elicited by lightly percussing along the course of the affected nerve from distal to proximal. When the finger percusses over the zone of regenerating fibers, the patient will announce the sensation of pins and needles, which may be quite painful, into the cutaneous distribution of the nerve.

How long is tinel's test?
This involves resting your flexed elbows on a table and allowing your wrists to fall freely into a flexed position. You'll hold this position for at least one minute. If you have carpal tunnel syndrome, you'll likely experience tingling or numbness in your fingers within a minute's time.
What is tinel's and Phalen's tests?
Tinel's sign and Phalen's test are two provocative tests used in the diagnosis of carpal tunnel syndrome. A review of the literature reveals a wide range of sensitivity for these tests.
What is the most accurate test for carpal tunnel syndrome?
To diagnose carpal tunnel correctly and develop a list of possible causes, an EMG/NCV (Electromyography/Nerve Conduction Velocity Study) is the most accurate and correct test and is required. Your doctor may order a 3T (Tesla) MRI If your doctor thinks it's possible you have carpal tunnel causing your hand/wrist pain.
How can you tell the difference between carpal tunnel and cervical radiculopathy?
Pain can occasionally occur in the forearm and even up into the shoulder. Some patients may complain of clumsiness. Symptoms of carpal tunnel syndrome are usually worse at night or with repetitive activity with that hand and wrist. Cervical radiculopathy occurs when a cervical nerve in the spine is compressed.
What nerve is affected in carpal tunnel syndrome?
Carpal tunnel syndrome (CTS) occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist. The carpal tunnel—a narrow, rigid passageway of ligament and bones at the base of the hand—houses the median nerve and the tendons that bend the fingers.
Tinel Sign and Nerves
The Tinel sign is the result of a simple, noninvasive test that checks for nerve problems. It involves tapping a finger along the problem nerve, which can produce tingling or pain. This sensation is a sign of nerve damage and is called the Tinel sign.
Tinel Sign Test Results
A positive Tinel sign means that tapping your nerve causes a tingling sensation to radiate through that area of your body. It’s sometimes described as a pins and needles feeling.
Limitations of the Tinel Sign
Results can vary based on the amount of pressure used on your wrist. If your doctor taps too hard or sharply, you will have tingling even if there isn’t a problem.
Other Tests
Since the Tinel sign isn’t a complete diagnosis, your doctor will do some other tests.
Considerations for Tinel Sign
The Tinel sign is an old test that doctors have used for a long time as part of physical examination. To confirm diagnosis of a nerve problem, other tests need to be done.
What is the Tinel sign?
Tinel's sign (also Hoffmann-Tinel sign) is a way to detect irritated nerves. It is performed by lightly tapping ( percussing) over the nerve to elicit a sensation of tingling or " pins and needles " in the distribution of the nerve. Percussion is usually performed moving distal to proximal. It is named after Jules Tinel.
Who invented the Tinel sign?
History. Tinel's sign takes its name from French neurologist Jules Tinel (1879–1952), who wrote about it in a journal article published in October 1915. German neurologist Paul Hoffmann independently also published an article on the sign six months earlier, in March 1915.
Who first described the sign of tingling in the peripheral nerve?
Paul Hoffmann described the sign in March of 1915 in On a Method of Evaluating the Success of a Nerve Suture. Several months later in October 1915, Dr. Jules Tinel published his work on the sign in The Sign of Tingling in Lesions of Peripheral Nerves.
Why does my ring finger tingle?
Multiple causes can result in ulnar nerve compression and damage at the cubital tunnel and cause symptoms such as tingling in the medial aspect of the forearm along with the little finger and medial aspect of the ring finger.
What is the sign of a cubital tunnel syndrome 11?
Tinel’s sign at the elbow is used to detect ulnar nerve entrapment at the elbow commonly known as cubital tunnel syndrome 11). To perform this test, have the patient’s elbow in a flexed position. Supporting the patient’s wrist with one hand, use the other hand to tap lightly at the medial cubital fossa. A positive test is reported when the patient experiences paraesthesias in the medial aspect of the forearm and/or into the medial one and a half fingers.
What is carpal tunnel syndrome?
Carpal tunnel syndrome is an entrapment neuropathy caused by compression of the median nerve as it travels through the wrist’s carpal tunnel 1). Carpal tunnel syndrome is the most common nerve entrapment neuropathy, accounting for 90% of all neuropathies. In the United States, carpal tunnel syndrome has an incidence of 1 to 3 persons per 1000 per year, with a prevalence of 50 per 1000, with similar incidence and prevalence in most developed countries 2). Carpal tunnel syndrome most commonly affects whites, has up to a 10 to 1 predominance in females, and has a peak age of 46 to 60 3). The carpal tunnel is located at the wrist on the palm side of the hand just beneath the skin surface (palmar surface). Eight small wrist bones form three sides of the tunnel, giving rise to the name carpal tunnel. The remaining side of the tunnel, the palmar surface, is composed of soft tissues, consisting mainly of a ligament called the transverse carpal ligament. This ligament stretches over the top of the tunnel.
What is the tinel sign?
In tarsal tunnel syndrome, the Tinel sign is positive if percussion of the posterior tibial nerve —found immediately behind the posterior tibial artery at the flexor retinaculum, behind the flexor digitorum longus tendon—produces paresthesia in the distribution of one or more of its two branches (the medial and lateral plantar nerves). Similar symptoms can sometimes be induced by simple pressure on the nerve beneath the flexor retinaculum. Inflating a sphygmomanometer cuff around the leg to produce venous congestion may also reproduce the paresthesia (positive tourniquet test). In anterior tarsal tunnel syndrome, the deep peroneal nerve, which travels with the dorsalis pedis artery, is entrapped under the extensor retinaculum, and the Tinel sign is often positive.
What is the first sign of a tinnel?
The first is Tinel's sign. This was described separately by Tinel and Hoffman in 1915. 24 Tinel sign is elicited by lightly percussing along the course of the affected nerve from distal to proximal.
What is the neuroma sign?
The neuroma sign is positive when pain is elicited in the distribution of the nerve when tapped. This sign means disruption of continuity of the whole nerve. The second and less well recognized sign is the tender muscle sign. This tenderness is elicited by squeezing the muscle that is being examined.
What does a positive Tinel's sign mean?
A positive Tinel's sign implies only fine-fiber regeneration, however, and tells the examiner nothing about the quantity or eventual quality of the new fibers. Over 50% of the World War Two soldiers who ultimately required resection and suture of nerve injuries had earlier shown an advancing Tinel's sign.
Does Tinel's sign indicate axonal regeneration?
Presence of a Tinel's sign provides some evidence favoring axonal regeneration. If paresthesias are obtained by distal nerve percussion, some continuity of sensory axons from the point percussed through the lesion to the central nervous system is suggested.
Can TTS be diagnosed without a TTS?
Without either of these two, it is clinically impossible to make a diagnosis of T TS. Obviously all suspected patients should have subjective burning and tingling paresthesias over the tibial nerve territory.
Purpose
Tinel's Sign is the general term for a test in which the therapist identifies an irritated nerve trough a percussive or tapping technique. At the elbow, Tinel's sign indicates an irritated Ulnar nerve.
Technique
The therapist should locate the Ulnar nerve that is seated in the groove between the olecranon process and the medial epicondyle, the Ulnar nerve is then tapped on repeatedly by the index finger of the therapist. A positive sign is indicated by a tingling sensation in the ulnar distribution of the forearm andhand distal to the tapping point.
