Rebound Tenderness Abdomen Definition
A clinical sign of PERITONITIS (generalized INFLAMMATION and INFECTION of the abdominal cavity). During abdominal palpation, the doctor presses slowly and firmly on the abdomen, then suddenly releases the pressure. The person feels a stabbing PAIN with release when the result is positive and notices no change when the result is negative.
Rebound tenderness has a high level of accuracy for both positive and negative results. Rebound tenderness often appears as referred pain in appendicitis. The pressure and release action applied to the left side of the abdomen results in the person feeling pain on the right side of the abdomen, at the approximate location of the appendix.
