Insights
Prematurity negatively impacts sensory processing, particularly tactile and vestibular functions, in infants. Early sensory evaluation is crucial for better motor development and outcomes in preterm infants.
Area of Science:
- Developmental Pediatrics
- Neuroscience
- Infant Health
Background:
- Prematurity is a potential risk factor for sensory processing difficulties.
- Research on sensory processing in preterm infants during the first year is limited, as issues can be subtle.
- Early detection of sensory processing dysfunction is vital for intervention.
Purpose of the Study:
- To investigate the association between prematurity and sensory processing in infants at 12 months of age.
- To examine the relationship between sensory processing and motor and cognitive development in preterm infants.
Main Methods:
- A cross-sectional study involving 45 infants, divided into preterm (<34 weeks gestation) and control (37-41 weeks gestation) groups.
- Sensory processing was evaluated using the Test of Sensory Functions in Infants (TSFI).
- Motor and cognitive development were assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III).
Main Results:
- The preterm group showed significantly lower overall TSFI scores, as well as reduced reactivity in tactile and vestibular domains.
- A positive association was found between the ocular-motor control domain of the TSFI and the Bayley-III motor score.
- No significant association was observed between Bayley-III cognitive scores and TSFI scores.
Conclusions:
- Prematurity adversely affects sensory processing, particularly tactile and vestibular functions.
- Enhanced sensory processing in ocular-motor control is linked to better motor performance at 12 months.
- Integrating sensory processing assessments into early evaluations can improve developmental outcomes for preterm infants.
Background:
Prematurity may be a risk factor for sensory processing difficulties. Limited research has investigated sensory processing in preterm infants in their first year of life, when sensory processing dysfunctions are more subtle and difficult to detect.
Aims:
The aims of this study were to investigate the association between prematurity and sensory processing and the associations between sensory processing and motor and cognitive development in infants at 12 months of age.
Study Design:
Cross-sectional study.
Subjects:
45 infants allocated in two groups: control (37-41 weeks' gestation) and preterm (<34 weeks' gestation).
Outcome Measures:
Sensory processing was assessed with the Test of Sensory Functions in Infants (TSFI). Motor and cognitive development was assessed with the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III).
Results:
Preterm group was associated with significant decrease in TSFI's total (p < 0.01), reactivity to deep tactile pressure (p = 0.02) and vestibular stimulation reactivity (p = 0.03) scores. Bayley-III motor score was positive associated with TFSI score on ocular-motor control domain (p = 0.03). Bayley-III cognitive score and TSFI scores were not significantly associated.
Conclusions:
Prematurity negatively interferes with sensory processing, especially in tactile and vestibular domains, and better sensory processing in ocular-motor control contributes to better motor performance at 12 months of age. It is important to consider sensory processing in early developmental evaluation and interventions to promote better developmental outcomes in preterm infants.
