POSTURAL BEHAVIOUR OF TERM SGA AND AGA NEWBORN INFANTS

Abstract

The authors studied the body posture at rest of 15 healthy term infants with birthweights appropriate for gestational age (AGA) and 15 infants who were small for gestational age (SGA). In both groups, there was wide inter-individual variability in postural behaviour. Apart from a preference for a position with all limbs in abduction between 1 and 90 degrees, independent of the degree of flexion or extension and internal/external rotation, no dominant preference posture could be seen for either group. The SGA infants showed a more flexed position of the arms, compared with the AGA group. One of the factors contributing to this difference might be the influence of intra-uterine malnutrition on the development of the central nervous system.
