“…However, by systematically placing electrodes in ventral and dorsal locations, we found that only electrodes placed ventrally (close to the hyoid) registered muscle activity during sucking, with dorsally placed electrodes only showing activity during swallowing (electronic supplementary material, figure S2). These results suggest that the muscles of the hyoid that are active during both sucking and swallowing may exhibit functionally relevant regional heterogeneity, with relatively small motor units that can only be accurately assessed with intramuscular fine-wire EMG, rather than surface EMG that is often used in limb muscles and for studies of human populations [47][48][49].…”

All mammalian infants suckle, a fundamentally different process than drinking in adults. Infant mammal oropharyngeal anatomy is also anteroposteriorly compressed and becomes more elongate postnatally. While suckling and drinking require different patterns of muscle use and kinematics, little insight exists into how the neuromotor and anatomical systems change through the time that infants suckle. We measured the orientation, activity and contractile patterns of five muscles active during infant feeding from early infancy until weaning using a pig model. Muscles not aligned with the long axis of the body became less mediolaterally orientated with age. However, the timing of activation and the contractile patterns of those muscles exhibited little change, although variation was larger in younger infants than older infants. At both ages, there were differences in contractile patterns within muscles active during both sucking and swallowing, as well as variation among muscles during swallowing. The changes in anatomy, coupled with less variation closer to weaning and little change in muscle firing and shortening patterns suggest that the neuromotor system may be optimized to transition to solid foods. The lesser consequences of aspiration during feeding on an all-liquid diet may not necessitate the evolution of variation in neuromotor function through infancy.

“…[44,71,72] Sucking microstructure, incorporating the number of sucks, sucks per burst, number of bursts, intra suck interval, and maximal sucking pressure can be acquired through intra-oral vacuum measurement, and it provides information about the feeding ability of infant throughout latching and feeding. Chen et al [46] proposed a device with an air-based pressure transducer, providing an objective assessment of infants' sucking microstructure. Utilizing this device, they recorded the intra-oral vacuum and compared the sucking microstructure for both breastfeeding and bottle-feeding.…”

A Review of Quantitative Instruments for Understanding Breastfeeding Dynamics

More than two decades ago, breastfeeding was recognized as the most effective international preventive health intervention, with the potential to prevent 13% of deaths among children younger than 5 years of age worldwide. [3] Studies have shown that infants who do not receive human milk are at higher risk for a number of medical issues, including necrotizing enterocolitis, [4,5] gastrointestinal and upper respiratory tract illness, [6,7] and urinary tract infections. [8] The World Health Organization suggests that all newborns should consume solely human milk during the first six months of life and continue with proper complementary foods until 2 years of age. [9] Breastfeeding has also been recognized as the ideal source of nourishment and the preferred primary feeding modality for infants by the American Association of Pediatrics. In addition, the US Surgeon General published a "Breastfeeding Call to Action" in 2011, touting the benefits of breastfeeding and encouraging all US families to pursue breastfeeding. [10] This renewed interest in breastfeeding fueled ongoing clinical and industrial investigations addressing different aspects of breastfeeding, including nutrition quality, breastfeeding duration, positioning, sucking and swallowing frequency, and latching effectiveness. [11,12] Throughout this review, we use the term "sucking," which refers to a complex interaction and coordination of an infant's jaw, hyoid bone, palate, pharynx, and tongue to coordinate milk removal during breastfeeding. [13,14] Additionally, the term "sucking microstructure" will be noted in different Breastfeeding, as a unique behavior of the postpartum period and an ideal source of nourishment, is profoundly impacted by the physiology and behavior of both mothers and infants. For more than three-quarters of a century, there has been an ongoing advancement of instruments that permit insight into the complex process of latching during breastfeeding, which includes coordinating sucking, swallowing, and breathing. Despite the available methodologies for understanding latching dynamics, there continues to be a large void in the understanding of infant latching and feeding. The causes for many breastfeeding difficulties remain unclear, and until a clearer understanding of the mechanics involved is achieved, the struggle will continue in the attempts to aid infants and mothers who struggle to breastfeed. In this review, the history of development for the most prominent tools employed to analyze breastfeeding dynamics is presented. Additionally, the importance of the most advanced instruments and systems used to understand latching dynamics is highlighted and how medical practitioners utilize them is reported. Finally, a controversial argument amongst pediatric otolaryngolo gists concerning breastfeeding difficulties is reviewed and the urgent need for quantification of latching dynamics in conjunction with milk removal rate through prospective controlled studies is discussed.

“…Over the last decades, high definition recording of nutrient intake within one single meal of solid or liquid food, or during breast-feeding, has been deployed in human research (12,28,45). More recently, data collection has been facilitated by a variety of wearable sensors, which detect meal patterns and food intake dynamics that occur under real-world circumstances (36).…”

This minireview focuses on the interpretative value of ingestive microstructure by summarizing observations from both rodent and human studies. Preliminary data on the therapeutic manipulation of distinct microstructural components of eating are also outlined. In rodents, the interpretative framework of ingestive microstructure mainly concentrates on deprivation state, palatability, satiation, and the role of learning from previous experiences. In humans, however, the control of eating is further influenced by genetic, psychosocial, cultural, and environmental factors, which add complexity and challenges to the interpretation of the microstructure of meal intake. Nevertheless, the presented findings stress the importance of microstructural analyses of ingestion, as a method to investigate specific behavioral variables that underlie the regulation of appetite control.
