Sensory oral motor and global motor development of preterm infants

摘要

BACKGROUND: development assessment of preterm infants. AIM: to evaluate the association between the gestational ages (GA) of premature infants with the global motor development as well as with early signs of sensory oral motor development delay, and to verify a possible association between them. METHOD: an exploratory study that assessed the development of 55 infants with corrected chronological ages between four to five months, born preterm at the Instituto Materno Infantil Professor Fernando Figueira (IMIP) and who were followed at the Kangaroo Mother Program Clinic between March and August of 2004. The assessment of the sensory oral motor development was performed through pre-selected indicators and of the global motor development through the Alberta Infant Motor Scale (AIMS). RESULTS: infants with lower GA (29 to 34 weeks) presented a higher median of risk signs in the sensory oral motor development assessment when compared to those with higher GA (35 to 36 weeks). Regarding the global motor development, infants born with lower GA presented a higher number of scores in the AIMS below percentile 10 (26%) when compared to those with a higher GA (4%) (p=0.009). The median index of the risk signs for the sensory oral motor development were significantly higher among infants with total AIMS scores below percentile 25 when compared to those with scores equal to or above percentile 25. CONCLUSION: the gestational age of infants at birth influenced the sensory oral motor and global motor development - infants with lower gestational ages presented worse performances. These findings suggest a possible association between both aspects of infant development.
