Abstract: The present invention provides a device that allows a user to intuitively understand the activity of peristaltic movement of a gastrointestinal tract. Provided is a method for automatic measurement of peristaltic movement using a computer. The method includes: an acquisition step of acquiring measurement information about biological activity of one or more parts of a gastrointestinal tract; an extraction step of extracting information about activity of the peristaltic movement from the measurement information about the biological activity acquired in the acquisition step; and a calculation step of obtaining an activity score representing the degree of the activity of the peristaltic movement based on the information about the activity of the peristaltic movement.

Abstract: An ultrasonic measurement device includes: a probe configured to be attached to a body surface of a subject while being in contact with the body surface, transmit ultrasonic waves into a body of the subject, and receive reflected waves of ultrasonic waves; and a controller configured to determine a contact state of the probe with the body surface. The controller determines the contact state of the probe with the body surface by comparing at least two received signals acquired through transmission and reception of ultrasonic waves by probe at different times.
