The leg test for appendicitis, also known as the psoas sign, is a clinical examination maneuver. A patient lies on their back, and the examiner applies resistance as the patient attempts to lift their right thigh. Pain in the right lower abdomen during this movement can indicate irritation of the psoas muscle due to an inflamed appendix. However, it's essential to consult a healthcare professional for an accurate diagnosis, as this test alone isn't definitive for appendicitis.
