Objective: The present study aimed to compare motor development of infants preterm samples from two regional Brazilian, using a reliable scale evaluation, to determine the influence that environmental context can have on infants exposed to perinatal conditions and similar risk factors. Methods: Two samples were used transverse infants with low birth weight: study group (SG = 70) and comparison group (CG = 43). The evaluation instrument used was the Alberta Infant Motor Scale (AIMS). Results: There were no statistically significant differences in total score on the AIMS, although they were no differences in the variables gestational age (at 2, 3 and 4 months) and birth weight (weight slightly larger than the GC) among infants. There was also a difference in the classification of motor development at 2 and 3 months of corrected age, according to the standard scale, in which GE was ranked as the latest GC. Conclusion: The results suggest that different regions of preterm infants exhibit the same trend in its motor, even if subjected to different environmental influences. It is suggested the extension of this study considering the more detailed control of the environment in which the infant is inserted, including maternal practices.

Estudo transversal, com 38 gemelares entre0 a 6 meses, de ambos os sexos, nascidos pré-termo, de baixo peso, sem morbidades graves no período neonatale sem sequelas neurossensoriais na alta hospitalar, oriundos do Hospital Materno-Infantil de Goiânia, GO, Brasil. Acoleta foi realizada por avaliadores treinados e composta por entrevista de anamnese, questionário socioeconômicoe avaliação do desenvolvimento motor com a AIMS. A análise dos dados foi cega, realizada por intermédio devideogravações e cada par de gemelares foi avaliado no mesmo dia. O primeiro e segundo gemelar (GI e GII)apresentaram variáveis neonatais semelhantes. Não houve diferença signifi cativa ao comparar o desenvolvimentomotor entre os pares. A maioria dos bebês foi classifi cada com desenvolvimento normal, sem diferença entre ospares. Conclui-se que os bebês gemelares pré-termo apresentaram variáveis neonatais e desenvolvimento motorsemelhantes, quando comparados entre GI e GII. Ressalta-se a importância de acompanhar o desenvolvimento dosbebês gemelares, sobretudo quando há associação com a prematuridade.Palavras-chave: Recém-Nascido Prematuro; Gêmeos; Desenvolvimento Infantil. ABsTRAcTThe aim of this study was to analyze the motor development of preterm twins from 0 to 6 months of chronologicalage corrected by the Alberta Infant Motor Scale (AIMS), and to compare the differences between the twins,considering birth order and neonatal variables. A cross-sectional study with 38 twins between 0 and 6 monthsold, of both genders, preterm, low birth weight, with no severe morbidity in the neonatal period, and withoutsensorineural sequelae at hospital discharge from the Maternal-Infant Hospital of Goiânia, GO, Brazil. The collectionwas performed by trained evaluators and was composed of anamnesis interview, socioeconomic questionnaireand motor development evaluation with AIMS. The data analysis was blindly performed, through video recordingsand each pair of twins was evaluated on the same day. The fi rst and second twins (TI and TII) presented similarneonatal variables. There was no signifi cant difference when comparing the motor development among the pairs.Most were classifi ed with normal development, with no difference between pairs. It concludes that preterm twinspresented similar neonatal variables and motor development, when compared to TI and TII. It is important tomonitor the development of twin infants, especially when there is an association with prematurity.Keywords: Premature; Twins; Child Development.
