Medical Eponyms

Markle Sign (1973)

The Markle Sign, Markle Test or Heel Drop Jarring Test is elicited in patients with intraperitoneal inflammation by having a patient stand on his or her toes and suddenly dropping down onto the heels with an audible thump.

The patient is asked to stand knees straight, with or without shoes. The clinician faces him and asks the patient to do as he does. The clinician stands on his toes for a few seconds and, relaxing suddenly, comes down with his full weight upon his heels with a definite thump. The unsuspecting patient does likewise and may be quite surprised to feel a definite pain wherever there is inflammation in the abdomen. Not only can he tell you, usually quite positively, if there is pain, but also he can tell just where the pain is most severe.
