Insights
Premature infants demonstrated self-regulation by preferring a rhythmic breathing teddy bear. This sensory experience promoted neurobehavioral development and increased quiet sleep in preterm infants.
Area of Science:
- Neonatal care
- Developmental neuroscience
- Infant behavioral studies
Background:
- Preterm infants often experience altered sensory environments.
- Rhythmic stimulation may influence infant self-regulation and development.
- Understanding sensory preferences in premature infants is crucial for optimizing care.
Purpose of the Study:
- To investigate if preterm infants can self-regulate their interaction with rhythmic sensory input.
- To determine the effect of a breathing teddy bear on infant sleep and neurobehavioral development.
- To assess infant preference and engagement with rhythmic stimulation.
Main Methods:
- Clinical trial involving 45 preterm infants (29-33 weeks conceptional age).
- Intervention group received a 'breathing' teddy bear; control group received a nonbreathing bear.
- Time-lapse videorecording and home sleep monitoring post-discharge were used.
Main Results:
- Infants with the breathing bear increased their contact time with the bear over two weeks.
- These infants showed more quiet sleep and a greater increase in quiet sleep postterm.
- Preterm infants demonstrated a preference for rhythmic stimulation.
Conclusions:
- Preterm infants can organize motor activity to express preferences for rhythmic stimulation.
- Exposure to rhythmic sensory input facilitates neurobehavioral development in premature infants.
- The breathing teddy bear intervention positively impacted infant sleep patterns.
Abstract:
This was a clinical trials study of self-regulation of rhythmic stimulation in preterm infants. Infants were enrolled in three regional hospitals and followed in four outlying hospitals. Forty-five premature infants, 22 males and 23 females, enrolled at 29-33 weeks conceptional age (CA) received in the isolette either a "breathing" teddy bear (set to breathe at one-half the infant's quiet sleep respiration rate) or a nonbreathing bear. Using time-lapse videorecording at a 60:1 ratio, subjects were recorded for 3 days at the beginning of the Intervention period and again for 3 days, 2 weeks later. After discharge from the hospital, the sleep of the subjects was monitored in the home for a 24-hour period on weeks 1, 2, 3, 4, and 5 after expected date of birth (postterm). Infants with a breathing bear spent more time in contact with the bear, and increased their contact over the two weeks. Postterm, the "breathing bear babies" showed more quiet sleep and a greater increase in quiet sleep over weeks. The results indicate that premature infants ("prematures") are capable of organizing their motility to express a preference for rhythmic stimulation, and that the experience facilitates neurobehavioral development.
