Q

What is the Carnett sign? How do you perform it?

A

sit-up test

After identification of the site of maximum
abdominal tenderness, the patient is asked to fold his or her arms across the chest and sit up halfway. The examiner maintains a finger on the tender area, and if palpation in the semisitting position produces the same or increased tenderness, the test is said to be positive for an abdominal wall syndrome.
