Preterm infants are observed to have reduced trunk extension in the prone position, rigid postural patterns while reaching a toy, fewer movement reactions, trunk rotation, head control, and muscle tone than term infants. To distinguish between the infant with typical motor development and the one with atypical / abnormal motor development and to follow up the level of their trunk controls is important to identify of the motor development delay in the early stage of life.~This cross-sectional study included 42 LBW infants and 43 NBW infants at between 3 and 9 months of age. We investigated the association between the gross motor function and the segmental trunk controls of the LBW infants at the 3-9 months of age compared to NBW infants.
This study aimed to examine the relation between trunk control and gross motor performance in LBW and NBW infants.
