“…Sucking is a very well-described behavior that is rhythmic with vertical tongue movement that either strips milk out of the nipple or creates pressure changes within the oral cavity. There is very little, if any, rhythmic jaw movement (da Costa et al 2010;German et al 1992German et al , 2004b). …”

Infant mammalian feeding consists of rhythmic suck cycles and reflexive pharyngeal swallows. Although we know how oropharyngeal sensation influences the initiation and frequency of suck and swallow cycles, the role of palatal sensation is unknown. We implanted EMG electrodes into the mylohyoid muscle, a muscle active during suckling, and the thyrohyoid muscle, a muscle active during swallowing, in eight infant pigs. Pigs were then bottle-fed while lateral videofluoroscopy was simultaneously recorded from the electrodes. Two treatments were administered prior to feeding and compared with control feedings: 1) palatal anesthesia (0.5% bupivacaine hydrochloride), and 2) palatal saline. Using the timing of mylohyoid muscle and thyrohyoid muscle activity, we tested for differences between treatment and control feedings for swallowing frequency and suck cycle duration. Following palatal anesthesia, four pigs could not suck and exhibited excessive jaw movement. We categorized the four pigs that could suck after palatal anesthesia as group A, and those who could not as group B. Group A had no significant change in suck cycle duration and a higher swallowing frequency after palatal saline ( P = 0.021). Group B had significantly longer suck cycles after palatal anesthesia ( P < 0.001) and a slower swallowing frequency ( P < 0.001). Swallowing frequency may be a way to predict group membership, since it was different in control feedings between groups ( P < 0.001). The qualitative and bimodal group response to palatal anesthesia may reflect a developmental difference. This study demonstrates that palatal sensation is involved in the initiation and frequency of suck and swallow cycles in infant feeding.

“…Since we were not aware of any study that had used the NOMAS in a longitudinal design, no benchmark existed to determine at what point in time an infant could be considered to have acquired a normal, mature sucking pattern. From a previous study, we know that infants' sucking patterns are occasionally abnormal ('arrhythmical') in one third of healthy term infants [21] . Apparently, additional factors come into play, e.g.…”

“…behavioural state, or hunger/satiety, which sometimes prevent the expression of a normal, mature pattern. Therefore, based on our findings in term infants [21] , we decided that an infant had acquired a normal sucking pattern if at least 2 out of 3 consecutive episodes were diagnosed as normal. The infant is said to have acquired a normal sucking pattern on the first normal pattern of these 3 episodes.…”

Background: Pre-term infants with bronchopulmonary dysplasia (BPD) are at risk of acquiring brain abnormalities. Combined with ongoing breathing difficulties, this may influence the development of their sucking patterns. Objective: To determine the longitudinal development of sucking patterns from birth until 10 weeks’ post-term age in pre-term infants with and without BPD. Methods: The sucking patterns of 16 pre-term infants with BPD and 15 pre-term infants without BPD were prospectively assessed with the Neonatal Oral-Motor Assessment Scale. The infants were matched for gestational age (<30 weeks). We recorded approximately 12 feeding episodes per infant, from 34 until 50 weeks’ post-menstrual age. We diagnosed the infants’ sucking patterns as normal, dysfunctional, or disorganized. Then, we examined the development of the sucking patterns in relation to relevant clinical characteristics. Results: Thirty (21%) of 142 feeding episodes of the pre-term infants with BPD and 36 (23%) of 156 of those without BPD were diagnosed as normal (non-significant). Of the abnormal patterns, 3 were diagnosed as dysfunctional and 229 as disorganized. Before term-equivalent age, definitely abnormal sucking patterns were more prevalent in the pre-term infants with BPD than in those without BPD: 69 (49%) and 47 (30%) episodes, respectively (χ² = 10.7, p < 0.01). In particular, the abnormal patterns including the item ‘incoordination’, defined as the inability to coordinate sucking and swallowing with breathing, were more prevalent: 36 and 15%, respectively (χ² = 6.37, p < 0.05). There was no difference between the two groups regarding the age at which they acquired normal sucking patterns. Relevant clinical characteristics did not influence the development of the sucking patterns. Conclusions: The developmental characteristicof sucking patterns in infants with BPD was that these infants were unable to coordinate swallowing with breathing. This was the case especially prior to term-equivalent age; after term-equivalent age, the development of sucking closely resembled that of pre-term infants without BPD.

“…SEF is usually expressed as the volume of milk taken in a given interval of time divided by the number of sucks in that interval and represents one of the most important parameters for monitoring the sucking pattern developmental course [13] [14].…”

“…The methods mostly used in literature for SEF estimation are not suitable for portable and low-cost devices: most of the studies estimate the milk volume intake by weighing the bottle [15] and/or by surveying the milk residual at the end [16] or during the feeding [13], implying some drawbacks related, e.g., to the measure rawness, the system nonportability [15] or the feeding interruption [13].…”

The Sucking Efficiency (SEF) is one of the main parameters used to monitor and assess the sucking pattern development in infants. Since Nutritive Sucking (NS) is one of the earliest motor activity performed by infants, its objective monitoring may allow to assess neurological and motor development of newborns. This work proposes a new ecological and low-cost method for SEF monitoring, specifically designed for feeding bottles. The methodology, based on the measure of the hydrostatic pressure exerted by the liquid at the teat base, is presented and experimentally validated at different operative conditions. Results show how the proposed method allows to estimate the minimum volume an infant ingests during a burst of sucks with a relative error within the range of [3-7]% depending on the inclination of the liquid reservoir
