Clinical Trial Summary

This is a randomized controlled trial to study an oromotor stimulation in combination with a reading curriculum in the NICU among preterm infants using oral muscle exercises, Language Environment Analysis (LENA) recordings, linguistic feedback, and a language curriculum to improve the neonatal inpatient oral feeding and language outcomes for preterm infants.

Description:

This project aims to examine how an intervention involving a 10-day oromotor stimulation in combination with a reading curriculum in the NICU can impact preterm infant oral feeding development and examine the additional impact on language development. Investigators plan to determine the effects of an oromotor stimulation beginning at 33 weeks corrected on preterm infants, born between 22-30 weeks in the Women & Infants NICU, as measured by the days to initiate oral feeding, days to complete oral feeding, hospital duration, and NTrainer Pacifier System measures. Infants randomized to standard care without oromotor stimulation will receive the reading curriculum as well. Secondary outcomes will include LENA (Language Environment Analysis) recordings measuring adult word count, infant vocalizations, conversational turns through audio recording obtained biweekly until 36 weeks corrected. Additionally, investigators aim to determine the effect of an intervention of oromotor stimulation with reading on maternal stress and perceived well-being in the NICU through a validated questionnaire completed prior to infant discharge and at the 1, 3, 7, and 12 month follow up visits. Final outcomes include examination of the long-term effect of inpatient oromotor stimulation and shared reading education on infant receptive and expressive language development at 12 and 24 months. Investigators hope this research will contribute to the growing research supporting the connection between oral feeding and language development in preterm infants and its impact on maternal-infant well-being.

Intervention

Behavioral:
• Oromotor stimulation
This will begin around 33 weeks corrected, the day following the first NTrainer measurements. The oral stimulation program will be modeled after the protocol designed and studied for preterm infants and will be implemented for a goal of 10 consecutive days within a 14 day period. This includes 10 minutes of stroking the cheeks, lips, gums, and tongue, and the final 5 minutes consisting of mid tongue stroking, eliciting a suck with gloved finger, and sucking on a pacifier provided in the NICU. This will occur 15-30 minutes before a scheduled tube feeding when the infant is tolerating bolus enteral feeds of 120 ml/kg/day for at least 48 hours. This will occur behind a curtain to ensure blinding of staff and parents. Modifications will be made for infants that remain intubated and only 10 minutes of the stroking of the cheeks, lips, gums, and tongue will occur. Stimulation will cease if episodes of oxygen desaturation and/or apnea/bradycardia occur during the stimulation.
• Reading curriculum
Written packets with biweekly lessons. The first two lessons include how to begin to read and talk to their baby. The second two lessons include reading or talking about the day using infant directed speech. The final two lessons include continuing to engage with the baby through interactive reading.
• LENA recording
The LENA device provides 24 hours of language recordings placed inside an infant vest. The recordings are uploaded to a computer which analyzes total adult word counts, infant vocalizations, conversational turns, background noise, and silence.
• LENA linguistic feedback
LENA recordings of adult word counts, infant vocalizations, and conversational turns will be provided in printed form after each recording with review of each recording and progress over time.
• No oromotor stimulation
This will begin around 33 weeks corrected, the day following the first NTrainer measurements. The standard care group will not receive any stimulation but will have a study personnel present behind a curtain to ensure blinding of family, staff, and investigators. The study personnel will remain behind a curtain for 10-15 minutes prior to a feed for 10 days over a 14-day period beginning when the infant is tolerated 120 mL/kg/day for at least 48 hours.

Outcome
