Hoffman-Tinel test, distal-tingling-on-percussion sign, Tinel sign.
A component of the physical exam to assess nerve compression or nerve entrapment. Most often it is utilized at the volar wrist for carpal tunnel evaluation but positive findings may be elicited at all superficial nerves. Tapping over the compressed nerve causes pain and paresthesia in a proximal or distal direction to the compressed nerve. A sensation of "pins and needles" occurs with percussion over the insulted nerve most often representing a partial nerve compression or early nerve regeneration.
