## Overview The skin twitch (cutaneous trunci or panniculus) reflex is tested by pinching the skin. In the neck, absence of the twitch in a specific area may indicate local cutaneous nerve damage or facial-nerve involvement. It is a useful part of the neurologic examination. ## What It Indicates Integrity of local sensory and motor nerves to the skin. ## Diagnosis Observation of the reflex during neurologic testing. ## Treatment Directed at the underlying nerve injury if present. ## Recovery and Prognosis Depends on the nerve lesion. ## Prevention Not applicable.
