Insights

Low birth weight (LBW) infants with atypical motor development exhibit poorer trunk control. Segmental trunk control is strongly linked to gross motor skills in both LBW and normal birth weight infants.

Area of Science:

  • Developmental Pediatrics
  • Motor Development Research

Background:

  • Trunk control is a critical component of overall gross motor development in infants.
  • Understanding factors influencing trunk control is essential for early identification of developmental delays.

Purpose of the Study:

  • To investigate the relationship between segmental trunk control and gross motor performance in low birth weight (LBW) infants.
  • To compare trunk control in LBW infants with typical versus atypical motor development.

Main Methods:

  • A cross-sectional study involving 42 LBW and 43 normal birth weight (NBW) infants aged 3-9 months.
  • Utilized the Segmental Assessment Trunk Control (SATCo) and Alberta Infant Motor Scale (AIMS) for evaluations.

Main Results:

  • A significant positive correlation (r=0.835, p=0.001) was observed between gross motor performance and segmental trunk control across all infants.
  • LBW infants with atypical motor development demonstrated significantly poorer trunk control compared to those with typical development (f=5.480, p=0.001).
  • Segmental trunk control was found to be 0.398 times lower in LBW infants compared to NBW infants.

Conclusions:

  • Segmental trunk control is a key predictor of gross motor performance in infants.
  • Poorer trunk control in LBW infants, particularly those with atypical development, highlights a potential area for targeted early intervention.
