Assessment of behaviour on the Brazelton scale in healthy preterm infants from 32 conceptional weeks until full-term age

20 healthy preterm infants were assessed weekly by the Brazelton Neonatal Behavioural Assessment Scale from 1–2 weeks after birth until they reached their expected date of birth. The gestational age of the infants ranged from 28 to 34 weeks. Although the full scale could not be used before 36 conceptional weeks. obvious progress in development was found for most items of the scale. In particular there was improvement in orienting responses and in motor performance during the observation period. At full-term age comparisons were made with a group of normal-term infants (n = 80). All premature infants underwent standard neonatal neurological examination at full term, and tests of neurological function and psychomotor development up to the age of 18 months.
