“…The scarf sign as assessed at 36 to 40 weeks PCA was positively correlated with higher levels on the motor performance assessment at 1, 2, 3, and 4 months of age adjusted for prematurity. This sign assessed at term age was found to have good validity indices for diagnostic testing as well as a significant relationship to active movement of the arm at four months adjusted age (Lekskulchai & Cole, 2000a). Ohgi, Gima, and Ariyama (2006) found that spontaneous upper extremity movements of premature infants have nonlinear, chaotic, and dynamic characteristics.…”

The aim of the present study was to assess the very early neurobehavioral development of preterm infants and to examine differences regarding sex. Two-hundred and two preterm infants were assessed by the Neurobehavioral Assessment of the Preterm Infant (NAPI), which was carried out at 32-37 weeks postconceptional age in the hospital setting. The infants' performance was compared to a norm-referenced sample and a comparison between groups regarding sex was also done. In comparison to the NAPI normreference, the preterm infants showed less muscular tonicity on the scarf sign, less vigor and spontaneous movement, higher alertness and orientation, weaker cry, and more sleep state. There was no statistical difference between males and females preterm infants at NAPI performances. Keywords: Preterm, neurobehavioral, sex. ResumoO objetivo do estudo foi avaliar o desenvolvimento neurocomportamental inicial de bebês prematuros e examinar as diferenças quanto ao sexo. Foram avaliados 202 bebês nascidos pré-termo pela Avaliação Neurocomportamental para Prematuros (NAPI), que foi realizada na fase de 32-37 semanas de idade pós-concepcional no contexto hospitalar. O desempenho dos bebês no NAPI foi comparado com a amostra de padronização do instrumento e também foi feita a comparação entre grupos diferenciados pelo sexo. Em relação à amostra de padronização, os bebês deste estudo apresentaram menor tonicidade muscular no sinal de cachecol, menor vigor e movimento espontâneo, mais alerta e orientação, choro mais fraco e mais estado de sono. Houve um padrão semelhante de desempenho neurocomportamental dos meninos e meninas nascidos prematuros. Palavras-chave: Prematuro, neurocomportamental, sexo.

Introduction: Preterm infants are vulnerable to developmental delays. Detecting problems at an early age is one of the challenges of professionals and researchers in the area. Objective: To analyse the motor development and to identify the risk factors associated with predictors of overall and motor delay in preterm newborns. Methods: Eighty preterm infants (50% female; mean gestational age = 33 ± 2.2 weeks) with low birth weight (average of 1,715 ± 437 g) were evaluated using the Neurobehavioral Assessment of the Preterm Infant (NAPI) during the neonatal phase (prior to term age), the Denver Developmental Screening Test II (DDST-II) between 2 and 8 months, the Test of Infant Motor Performance between 2 and 4 months regarding motor development and the Alberta Infant Motor Scale between 4 and 8 months. Results: Neurobehavioural delay was noted in 24% of the infants in the neonatal phase. Between 2 and 8 months, the delay in overall development was ≥ 31% and the delay in motor development was 35-36 %. Decreased levels of alertness, orientation, motor development and vigour according to the NAPI were shown to be predictive of a delay in development between 4 and 6 months of age. The delay in overall development between 2 and 6 months was predictive of a delay in motor development between 6 and 8 months. Conclusion: Neurobehavioural variables, hospital stay and overall delay are good predictors of motor development during the first year of age.
