Known for its cutting-edge diagnostic feature for a wide range of application from clinical use to laboratory studies, including the diagnosis of irritable bowel syndrome (IBS).

When a bolus or gas enters, the digestive tract reacts to this stimulation with its motility represented as peristatic reflex or intestinal reflex, and provides an organic sensation by transmitting a signal conveying the status of internal organs to the brain.
