Which maneuver describes the Tinel's sign protocol?

• A. Repetitive light tapping over the nerve pathway such as at the carpal tunnel or cubital tunnel.
• B. Palpation with deep pressure over the motor point of muscle.
• C. Quick passive finger flexion repeated to provoke symptoms.
• D. Electrical stimulation of the spinal cord.

Answer: (A)

Tinel's sign is about provoking nerve irritation by tapping along a nerve’s path. The main idea is simple: light percussion over a superficial nerve—like the median nerve at the carpal tunnel or the ulnar nerve at the elbow—can spark tingling or a shock-like sensation that travels along the nerve’s distribution if the nerve is irritated or compressed. A positive result points to entrapment at that site or nerve regeneration nearby. This differs from palpating a motor point, which focuses on muscle innervation rather than nerve irritation; and it differs from other provocative tests that use movement or sustained positions (for example, wrist flexion tests) to elicit symptoms. Electrical stimulation of the spinal cord is not a peripheral nerve test and doesn’t assess focal nerve entrapment.
