Insights
Premature infants
Area of Science:
- Pediatrics
- Neonatology
- Developmental Neuroscience
Background:
- Infants born prematurely face increased risks of developmental challenges, including motor deficits.
- Early identification of motor dysfunction in preschool-aged children is vital for their exploration and development.
- Premature birth can lead to long-term cognitive and behavioral issues.
Purpose of the Study:
- To present initial data on gross motor development in children born prematurely.
- To identify the prevalence and characteristics of persistent motor delays in this population.
- To analyze motor outcomes in relation to gestational age and birth weight.
Main Methods:
- Retrospective chart review of infants in a neonatal follow-up program.
- Standardized gross motor assessments by a single physiotherapist from birth to age 2.
- Analysis of 97 children with a mean gestational age of 31.1 weeks and mean birth weight of 1.66 kg.
Main Results:
- Most children exhibited average gross motor skills.
- Children born very preterm (VPT) or moderately preterm (MPT) with low birth weight were more likely to have below-average scores.
- Late preterm (LPT) infants were most frequently referred for physiotherapy due to gross motor delays.
Conclusions:
- Periodic monitoring of premature children's motor development is essential.
- A significant proportion of initially delayed children normalized by follow-up.
- Further longitudinal research is needed for moderate and late preterm children's motor outcomes.
Abstract:
The developing brain of a premature infant is vulnerable to injury. As a result, the long-term consequences of a premature birth include motor deficits, cognitive and behavioural problems. It is crucial to identify motor dysfunction during the preschool period because it interferes with a child's ability to explore the world. The goals of this study were to (1) provide preliminary data on the gross motor outcomes of children born prematurely and (2) determine the proportion and characteristics of the children who had maintained delays over the course of follow-up. A retrospective chart review was conducted on all infants monitored by a neonatal follow-up programme. Each child was assessed by a single physiotherapist from birth until age 2 years. Of the 107 cases identified, 97 individuals were retained for analysis; they had a mean gestational age of 31.1 (SD 2.9) weeks and a mean birth weight of 1.66 (SD 0.53) kilograms. The majority of children assessed were found to have gross motor outcomes in the average range. Children with scores below the average range were most often born very preterm (VPT) or moderately preterm (MPT), with very low or low birth weight, respectively. A total of 17 participants were referred to physiotherapy to address the gross motor delays identified in the follow-up programme; 14 of these 17 had previously been identified as delayed and were being monitored. Late preterm (LPT) children (n=6) were most often referred, followed by those born extremely preterm (EPT) and VPT (n=4). In total, 56 children were identified as delayed at one assessment point but were found to be within normal limits by the end of the follow-up period. It is important to periodically monitor premature children. A longitudinal, population-based study is also needed to provide more data on the predictors and long-term motor outcomes of MPT and LPT children.
