What does no guarding or rebound refer to on medical exam?

"No guarding" refers to the absence of involuntary muscle tensing or flinching in response to touch, which can indicate abdominal pain. "No rebound" refers to the absence of increased pain when pressure is released after it is applied to an area, which can be a sign of peritoneal irritation. These findings are important during a physical exam to assess for possible underlying conditions like appendicitis or peritonitis.
