ABSTRACT

PURPOSE: To analyze the oral and general motor behavior of newborns from women that used crack and/or cocaine when pregnant and verify if there is any relationship between the development of the oral and the general sensorimotor systems.
METHODS: Cross-sectional study assessing 25 premature and full-term newborns from women who were crack and/or cocaine users and comparing them to another group composed of 25 newborns without the studied factor. The oral and general sensorimotor systems were evaluated by using the Preterm Infant Oral Feeding Readiness Assessment Instrument and the Test of Infant Motor Performance (TIMP). The results compared scores found in both scales and their relationship to the use of crack and/or cocaine during pregnancy.
RESULTS: No deviation was found by the TIMP when comparing the newborns from crack and/or cocaine-using mothers to the ones from non-using mothers. The results from the Preterm Infant Oral Feeding Readiness Assessment Instrument showed deviations. A relationship between the results from babies who presented a delayed TIMP and a lower score in the Preterm Infant Oral Feeding Readiness Assessment Instrument was observed.
CONCLUSION: The low performance observed in the Preterm Infant Oral Feeding Readiness Assessment Instrument suggests that oral motor responses change with the use of drugs during pregnancy. The correlation between both instruments shows that the development of the oral sensorimotor system can be related to general motor development.
