  ABSTRACT: No consensus exists concerning the influence of head position and head position change on body posture and motility. Especially the existence of an asymmetric tonic neck reflex (ATNR) in full-term newborns is an issue of discussion. Three-hour video recordings were made of 15 full-term appropriate for gestational age (AGA) and 15 full-term small for gestational age (SGA) infants between the third and eight postnatal day. During a playback of the video recording head position, head position change and several movement patterns of the four limbs were fed into a computer using an event-detecting program. Furthermore, spontaneous head turnings were selected and body posture just before, immediately at and 1 min after the head turning were sketched. The data were analyzed concerning: (1) influence of head position on symmetry of movement of the four limbs; (2) the existence of an ATNR and ATNR-related patterns. In both AGA and SGA infants all movement patterns except hand-face and hand-mouth contact showed a symmetrical distribution, independent of head position. Furthermore, the occurrence of an ATNR following a spontaneous head turning in both AGA and SGA infants was rare. From our results it may be concluded that the ATNR is rare in full-term AGA and SGA newborns. Furthermore, this study demonstrates that head position is not a major factor influencing quantitative aspects of spontaneous motor behaviour. The results are of clinical importance as they imply that in the examination of the neurological condition of the full-term newborn infant by means of observation of spontaneous posture and motility, head position is not of major importance.

  ABSTRACT: 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.

  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.
