Purpose[edit | edit source]
Tinel's test is used to test for compression neuropathy, commonly in diagnosing carpal tunnel syndrome.[1]
Technique[edit | edit source]
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.[2] 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.[1]
Positive test: The test is positive when a tingling or prickling sensation is felt in the distribution of the nerve.
Conditions that have been associated with a positive Tinel's sign
- Carpal Tunnel syndrome
- Cubital tunnel syndrome
- Radial nerve entrapment
- Tarsal tunnel syndrome
- Superficial peroneal neuropathy, and
- Thoracic outlet syndrome.
