What does Tinel's sign protocol involve?

• A. Repetitive light tapping over a nerve pathway such as the carpal tunnel or cubital tunnel.
• B. Palpation of the carpal tunnel with pressure.
• C. Resisted wrist extension to provoke symptoms.
• D. Diagnostic imaging of peripheral nerves.

Answer: (A)

Tinel's sign is a provocative nerve test. By lightly tapping along the course of a nerve, such as at the carpal tunnel in the wrist or the cubital tunnel at the elbow, you can provoke tingling or an electric shock-like sensation in the nerve’s distribution if the nerve is irritated or compressed. A positive response indicates nerve irritability rather than a structural problem detectable by imaging. This is why tapping over a nerve pathway best describes the sign. It isn’t about pressing for palpation, resisted movements, or imaging findings.
