Positive test:Both Phalen test and Reverse Phalen's tests are considered positive when the patient's symptoms are reproduced, test gives the same symptoms as that experienced with carpal tunnel syndrome, namely paresthesia (buring, tingling, numbness) in the distribution of the median nerve. [2][3]
What is the Phalen test?
Phalen test is a stirring test for carpal tunnel functions. This is why the other name of the Phalen test is a carpal tunnel test. A patient who has nerve compression in the carpal tunnel slightly feels the tingling sensation on the top of their wrist.
How reliable is the reverse Phalen test?
Paresthesia in the region supplied by the median nerve is a sign of carpal tunnel syndrome. The reverse Phalen test is less reliable than the Phalen test. For Reverse Phalen Test, a study by de Krom and colleagues 2 found the test to have a sensitivity of 41 % and a specificity of 55 %.
Is Phalen test the golden standard diagnostic test for carpal tunnel syndrome?
This study also found that the combination of Phalen test with Durkan’s test has a sensitivity of 94% and a specificity of 96%, thus equalling the respective values for electrophysiological testing (nerve conduction velocity, EMG) which so far is regarded as the golden standard diagnostic test for Carpal Tunnel Syndrome.
What is the significance of a positive Phalen's sign?
Signs and Symptoms A positive Tinel sign is usually present over the median nerve as it passes beneath the flexor retinaculum (Fig. 50.2). A positive Phalen maneuver is highly suggestive of carpal tunnel syndrome.
What does Phalen's test show?
The clinical term “Phalen's Maneuver” refers to a provocative test used in the diagnosis of carpal tunnel syndrome. We also know this as a wrist-flexion test 1. Carpal tunnel syndrome (CTS) refers to a condition that puts pressure on a nerve in your wrist.
What's a positive sign of carpal tunnel syndrome?
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.

What is the best test to diagnose carpal tunnel syndrome?
The nerve conduction velocity test is one of the most dependable ways to diagnose carpal tunnel syndrome. By measuring how fast an electrical signal travels along the forearm's nerve or from the nerve to a muscle, this test can produce reliable evidence of the syndrome.
How is carpal tunnel syndrome diagnosed?
The doctor will tap or press on the median nerve in your wrist with a reflex hammer. If your fingers tingle or if you feel an electric-shock-like sensation, the test is positive. You may have carpal tunnel syndrome. This is also known as the wrist-flexion test.
When is surgery needed for carpal tunnel?
Surgery is usually only considered if symptoms return regularly and problems associated with the painful sensations increase despite trying other treatments such as splints or corticosteroid injections. In those cases surgery can provide better relief than repeat injections or splint treatments.

What Is The Phalen Test?
To assess carpal tunnel syndrome, the doctors are conducting this test. The medical examiner has indirectly flexed the patient’s wrist but without pressuring the wrist. While maintaining the shoulder and elbow are in the same extension. This subject was given to hold this position for at least 60 seconds.
How To Perform Clinical Examination Of Phalen test?
But if you want accurate results, you must process the whole examination steps under a specialized medical practitioner.
What Is Reverse Phalen’s Test?
The reverse Phalen’s test is used to evaluate the median nerve compression. This is a test that is conducted to diagnose carpal tunnel syndrome. The patients are asked to keep both hands wrists in the complete extension positions for at least 60 seconds.
How accurate is the hand elevation test?
The hand elevation test is comparable in accuracy to the Phalen test and only requires the patient to hold her arm over her head as high as comfortably possible. Reproduction of CTS symptoms within 1 minute is considered a positive test.
Is a positive phalen maneuver a CTS?
Although the Tinel sign and a positive Phalen maneuver are classic clinical signs of CTS, their actual utility in the diagnosis has been less clear.
Which test is the most sensitive?
Phalen test were the most sensitive (71%, p=0.02) and the most specific (75.5%, p= 0.01) amongst the physical examination tests (Table 1).
What is a carpal tunnel test?

The test is positive (suggestive of carpal tunnel syndrome) when wrist flexion produces numbness in the distribution of the median nerve. The accuracy of the test is limited. Also known as Phalen's sign.
What test is used to diagnose carpal tunnel syndrome?
Diagnosis of carpal tunnel syndrome is mainly clinically.5 Typical history and various clinical tests like Phalen test, Durken compression test and Tinel test are sufficient to make diagnosis.6 Anyhow its presence may be confirmed with various tests like Nerve conduction study and EMG1 These tests are useful to stage the degree of nerve compression and may therefore assist the surgeon and patient in anticipating the time needed for recovery of nerve function.
What does a positive Tinel's sign mean?
A positive result means you feel a tingling sensation when your doctor taps the affected nerve. However, you can have a normal result, meaning you don’t feel any tingling, while still having a nerve injury.
How does a nerve test work?
This test helps your doctor evaluate how well your nerves function. They’ll stimulate several areas along the affected nerve using electrodes on your skin. It will measure the speed of the nerve and determine if there are areas where the impulse is slowed.
How many people with carpal tunnel have positive results?
of 100 people with carpal tunnel syndrome found that only 25 percent of participants had a positive result for Tinel’s sign. However, another study. As a result, your doctor will likely use some additional tests to confirm whether or not your nerve is compressed.
What is the Tinel sign?
Tinel’s sign, previously known as the Hoffman-Tinel sign, is something doctors use to check for nerve problems. It’s commonly used to diagnose carpal tunnel syndrome. However, the test can also be used to test for other nerve conditions, such as cubital tunnel syndrome, tarsal tunnel syndrome, or radial nerve injuries.

Clinically Relevant Anatomy
Summary of CTS
- The phalen’s test is a provocative test used in the diagnosis of CTS. This occurs when the median nerve is compressed or squeezed at the wrist. [4C,5F] The pain is often worst at night. Daily activities such as driving and typing may increase the symptoms. [5F] The most common complaints are; 1. pain and tingling of hands and fingers 2. numbness in...
Technique
- The patient places her flexed elbows on a table, allowing her wrists to fall into maximum flexion. The patient is asked to push the dorsal surface of her hands together and hold this position for 30-60 seconds. This position will increase the pressure in the carpal tunnel, in effect compressing the median nerve between the transverse carpal ligament and the anterior border of the distal en…
Evidence
- Reliability: One study has shown that the intra-rate reliability standard is moderate and that the inter-rater reliability appears to be good. [10C] From another study shows the Phalen test sensitivity (0.64), specificity (0.75), positive likelihood ratio (2.54) and negative likelihood ratio (0.49) were measured. Therefore, when a positive Phalen's test is finding it is more likely that the…
