Which diagnostic sign is associated with appendicitis?

Rovsing's Sign is associated with appendicitis and is indicative of irritation of the appendix. This sign is observed when pressure is applied to the left lower quadrant of the abdomen, which can cause pain in the right lower quadrant if appendicitis is present. The rationale behind this is that the movement of the intestine and the stretching of the peritoneum may trigger pain in the area where the inflamed appendix is located.

Murphy's Sign is primarily linked to gallbladder inflammation, specifically cholecystitis, as it tests for pain experienced when the examiner asks the patient to take a deep breath while palpating the right upper quadrant. Psoas Sign indicates irritation of the iliopsoas muscle and is more connected to retrocecal appendicitis or other causes of hip flexor irritation. Brudzinski's Sign is a test for meningitis and involves involuntarily lifting the legs when the neck is flexed, which is not related to appendicitis. Thus, Rovsing's Sign stands out as the diagnostic indication specifically associated with appendicitis.
