The physical mechanisms executed by the infant during breastfeeding have been intriguing topics that lead to a long scientific controversy; whether it is sucking of the milk or mouthing of the nipple/areola. We developed a dynamic analysis of ultrasound video clips acquired during breastfeeding in order to explore the kinematics of the tongue. Then, we have developed a three-dimensional biophysical model of the breast and lactiferous tubes that enabled mimicking latch-on and the dynamic characteristics of the tongue and nipple observed in ultrasound imaging during breastfeeding. Then, we simulated breastfeeding and explored the biomechanical aspects of breastfeeding. We demonstrated that latch-on to draw the nipple/areola into the infant mouth, as well as milk extraction during breastfeeding, require development of time varying sub-atmospheric pressures within the infant's oral cavity. Analysis of infant tongue motility was compared between breast and bottle feeding. The presentation will also include discussion of oral pressure measurements.
Objective 1: Background on mechanics of motions and bioengineering studies.
Objective 2: Kinematics of tongue movement derived from objective analysis of individual frames
Objective 3: Biomechanical model of milk extraction during breastfeeding based on first physical principles (i.e., Newton Laws).
