“…Nevertheless, neurological maturation as determined by these tests appeared to be somewhat retarded in the FNR group. This is in good agreement with a recent comparison of human full-term light-for-dates and normal babies [21]. Within a week of birth, several reflexes and motor responses were tested and scored for strength and completeness on a threepoint scale.…”

Rats were subjected to growth retardation either from conception to 5 days of postnatal age (FNR group) or during the period 5–25 postnatal days (IR group). The rat at 5 days of age has reached a stage of brain development comparable with the human baby at term. Hence the FNR group may serve as a model for the small-for-dates baby. Compared with well-nourished controls both restricted groups showed deficits in neurological maturation. Both brain weight and body weight in adulthood were significantly reduced by earlier growth restriction; these changes were less marked in FNR than in IR animals. Cerebellar weight was consistently reduced more than that of the remainder of the brain. Brain stem acetylcholinesterase activity in adulthood was significantly higher than normal in IR, but not in FNR animals.

“…Intrauterine malnutrition has been demonstrated to modify several processes in brain development (4, 5, 26). Significant differences in neonatal neurological and neurobehavioural performance between full-term SGA and appropriate for gestational age (AGA) infants were described by several authors (1,8,15,19,21). In contrast, Ounsted et al (22) did not find any differences in neonatal behaviour between full-term SGA and AGA infants until two months postnatal age.…”

Quality of Spontaneous General Movements in Full-Term Small for Gestational Age and Appropriate for Gestational Age Newborn Infants

et al. 1994

Quality of spontaneous movements was studied in 15 healthy full-term appropriate for gestational age (AGA) and in 15 full-term small-for gestational age (SGA) newborn infants. All general movements with a minimal duration of 20 seconds were judged on different aspects of movement quality. From the general movements in each group (AGA: n = 106; SGA: n = 187), dominant patterns were isolated. In the AGA Group 3 dominant patterns of general movements were present. In the SGA Group 5 dominant patterns of general movements were found. Three of those were identical to the movement patterns in the AGA group, the remaining two patterns were unique for the SGA infants. Our results indicate that the three different types of general movements which constitute the major part of the normal repertoire of healthy full-term infants can be used as a reference for normal spontaneous motor behaviour. The two different types of general movements in the SGA infants might be used to discriminate between healthy and neurologically suspect newborn infants. The difference in movement pattern between AGA and SGA infants might be explained by the effect of intrauterine malnutrition on CNS development.

-Objective: To compare visual function and fine-motor control of full-term infants small-for-gestational age (SGA) and appropriate for gestational age (AGA), in the first three months. Method: We evaluated prospectively 31 infants in the 1 st month; 33 in the 2 nd and 34 infants in the 3 rd month, categorized as full-term; birth weight less than 10 th percentile for SGA and 25 th to 90 th percentile for the AGA group. Genetic syndromes, infections, multiple congenital malformations were excluded. The Bayley Scales of Infant Development-II were used, especially items related to visual function and to fine-motor control outcomes. Results: The Motor Index Score (IS) was significantly lower in the SGA group in the 2 nd month. The items "attempts to bring hands to mouth", in the 1 st month and "reaches for suspended ring", in the 3 rd month showed higher frequency in the SGA group. Conclusion: The Motor IS was lower in the 2 nd month and items of finemotor control in the 1 st month and in the 3 rd month showed higher frequency in the SGA group.
