Abstract

The ability to detect and evaluate ingestion is especially important in toddlers. The development of new methods for detecting and accurately measuring ingestion is therefore extremely important. One of the methods allowing such measurements is speckle pattern analyses, a well-known phenomenon in coherent imaging. The method allows extraction of various medical parameters, such as blood pulse pressure, temporal signature of heartbeats and breath. The current work contains further development and application of the speckle tracking technique for remote detection and quantification of swallowing and distinguishing between sucking and swallowing to identify feeding disorders in infants and elderly individuals.

Highlights

Remote detection of irregularity in the sucking–swallowing composition could indicate the existence of a feeding problem before it affects an infant
Because the sucking–swallowing sequence and composition could indicate the existence of a feeding problem, the remote detection of feeding problems is very important
The developed new method for remote detection and quantification of water sucking and swallowing is based on the analyses of secondary speckle patterns reflected from the subject’s neck

Summary

Introduction

The ability to detect and evaluate ingestion is especially important in toddlers. The development of new methods for detecting and accurately measuring ingestion is extremely important. Together, these functions are responsible for the swift and safe transport of milk boluses from the oral cavity to the stomach[2–4]. The present research is devoted to the remote evaluation of swallowing among adults and especially among infants by modeling sucking–swallowing patterns to determine whether a baby is breastfeeding and, if so, to measuring milk consumption. Because the sucking–swallowing sequence and composition could indicate the existence of a feeding problem, the remote detection of feeding problems is very important
