In gastroenterology, the<unk>  is a physical examination maneuver that can be used to detect the presence of ascites. It is useful for detecting small amounts of ascites—as small as 120 mL; shifting dullness and bulging flanks typically require 500 mL. The steps are outlined as follows: # Patient lies prone for 5 minutes # Patient then rises onto elbows and knees # Apply stethoscope diaphragm to most dependent part of the abdomen # Examiner repeatedly flicks near flank with finger. Continue to flick at same spot on abdomen # Move stethoscope across abdomen away from examiner # Sound loudness increases at farther edge of<unk>  # Sound transmission does not change when patient sits In relation to auscultatory percussion, the<unk>  is more specific, but less sensitive.
