Napoleon-Zeichen (engl. abdominal compression test, belly press test, Napoleon test): Also referred to as "Napoleon-Test" or "Belly-Press-Test". The abdominal compression test is used to assess the function of the subscapularis muscle, i.e. a possible tear of this shoulder muscle. The patient presses his or her palm against his or her abdomen in the way Napoleon used to put his hand on his belly (see image). Is the patient able to hold his wrist straight, the test is rated negative, i.e. normal muscle function. If the patient is unable to hold his wrist straight, the test is positive, the muscle function is compromised, and a muscle tear likely.
