WebJun 28, 2024 · The peristalsis is therefore characterized as a wavelike movement inside flexible tubes triggered and operated by a physiological flexion and extension of adjacent locations, which leads to a movement of the within contents. In medicine, the fluid wave test or fluid thrill test is a test for ascites (free fluid in the peritoneal cavity). It is performed by having the patient (or a colleague) push their hands down on the midline of the abdomen. The examiner then taps one flank, while feeling on the other flank for the tap. The pressure on the midline prevents vibrations through the abdominal wall while the fluid allows the tap to be felt on the other side. The result is considered positive if tap can be felt on t…
