“…Therefore, it seems that IST is a valid instrument for measuring the suction pressure in infants. The difference in sucking measures of preterm and full-term children was reported in similar studies [23]. According to IST results, preterm infants not only have weaker suction pressure but also produce positive suction pressure.…”

Objectives: Most preterm infants experience oral feeding disorder. Sucking is the most appropriate way for oral feeding, but it may be immature in preterm infants. Regarding the increased risk of feeding problems in preterm infants, investigating and monitoring their sucking patterns to present appropriate and timely intervention is recommended The current research aimed to report the design of an instrument for measuring the suction pressure in preterm infants through a pilot study. We also checked the validity and reliability of the instrument. Methods: A pilot study was conducted to measure the validity and reliability of this instrument. First, the instrument was developed, and in the next step, discriminant validity, test-retest reliability, and comparison in terms of sex were investigated by measuring the suction pressure of 20 full-term and 15 preterm infants. The Mann-Whitney U test and Wilcoxon test were used to establish the discriminant validity, comparison in terms of sex, and test-retest reliability in SPSS v. 23 software. Results: Two groups showed a significant difference in the suction pressure (P<0.001) to support the discriminant validity of the instrument. We obtained satisfactory values for the test-retest reliability in two groups (r=0.97, P<0.001). Boys and girls did not significantly differ between full-term (P=0.9) and preterm infants groups (P=0.5). Discussion: Performing the pilot study on 35 infants through an infant sucker tester proved the instrument’s discriminant validity and test-retest reliability. However, conducting the studies with a larger sample size is essential to make this instrument available commercially.

“…Advanced treatment techniques were also have been available but still they need an experienced person for clinical practice [ 22 23 24 25 26 27 ]. Medoff-Cooper B et al, used multisensory approach to improve sucking pattern such as auditory, tactile and vestibular stimulation to improve feeding performance in infants [ 18 ].…”

Background: Oro-motor intervention methods were previously adopted to improve the sucking pattern but there is still a lag in the structured protocol for improving sucking behavior in infants with immature sucking. Thus, this study is aimed to develop a structured protocol for the Oro-motor intervention to improve sucking behavior. Method: Using the prospective observational study design, neonates with poor suck (producing less than 10 sucks per minute), under NG tube feeding, and maintaining oxygen saturation at room air were included. A total of 6 subjects were enrolled in this study and they were treated with Oro-motor intervention protocol. The Sucking rate and LATCH score were taken as the outcome measures and measured at beginning of intervention and after 2 weeks of intervention. Result: The mean pre-test and post-test values for sucking rate were is (8.66), (32.5) and LATCH were (4.66), (8.16) respectively. The data collected showed that the protocol framed for Oro-motor intervention was significantly effective in improving quality of feeding among infants with immature sucking behavior. Conclusion: The structured Oro-motor intervention protocol improves the feeding performance in infants with poor sucking behavior and improves the LATCH score. All the infants included in this study where under nasogastric tube feeding, thus the structured protocol can be considered to be helpful in weaning from NG tube feeding.

“…The authors concluded that quantitative measures of oral-motor function might serve as a proxy for neurodevelopment. In subsequent investigations using the Orometer and accompanying software, factor analysis of the more than 40 metrics collected by the system, identified seven factors that that best represent feeding skills as measured by the device: suck vigor, endurance, resting, irregularity, frequency, variability, and bursting ( 87 ). However, it is not clear the degree to which these specific measures might be sensitive to neurodevelopment.…”

Abnormal Nutritive Sucking as an Indicator of Neonatal Brain Injury

A term neonate is born with the ability to suck; this neuronal network is already formed and functional by 28 weeks gestational age and continues to evolve into adulthood. Because of the necessity of acquiring nutrition, the complexity of the neuronal network needed to suck, and neuroplasticity in infancy, the skill of sucking has the unique ability to give insight into areas of the brain that may be damaged either during or before birth. Interpretation of the behaviors during sucking shows promise in guiding therapies and how to potentially repair the damage early in life, when neuroplasticity is high. Sucking requires coordinated suck-swallow-breathe actions and is classified into two basic types, nutritive and non-nutritive. Each type of suck has particular characteristics that can be measured and used to learn about the infant's neuronal circuitry. Basic sucking and swallowing are present in embryos and further develop to incorporate breathing ex utero. Due to the rhythmic nature of the suck-swallow-breathe process, these motor functions are controlled by central pattern generators. The coordination of swallowing, breathing, and sucking is an enormously complex sensorimotor process. Because of this complexity, brain injury before birth can have an effect on these sucking patterns. Clinical assessments allow evaluators to score the oral-motor pattern, however, they remain ultimately subjective. Thus, clinicians are in need of objective measures to identify the specific area of deficit in the sucking pattern of each infant to tailor therapies to their specific needs. Therapeutic approaches involve pacifiers, cheek/chin support, tactile, oral kinesthetic, auditory, vestibular, and/or visual sensorimotor inputs. These therapies are performed to train the infant to suck appropriately using these subjective assessments along with the experience of the therapist (usually a speech therapist), but newer, more objective measures are coming along. Recent studies have correlated pathological sucking patterns with neuroimaging data to get a map of the affected brain regions to better inform therapies. The purpose of this review is to provide a broad scope synopsis of the research field of infant nutritive and non-nutritive feeding, their underlying neurophysiology, and relationship of abnormal activity with brain injury in preterm and term infants.
