Objectives:: To analyze the motor development of late preterm newborn infants (LPI) from birth to term-corrected age using the Test of Infant Motor Performance (TIMP) and to compare the obtained results with those of term infants at birth.
Methods:: Prospective cohort study, 29 late preterm newborn infants were evaluated by the TIMP at birth and every two weeks until term-corrected age. The TIMP was administered to 88 term infants at birth.
Results:: The mean TIMP score of late preterm newborn infants was 51.9±5.8 at 34-35 weeks and 62.6±5.2 at 40 weeks. There was a significant increase at 38-39 weeks in the LPI group (p<0.05). There were no significant differences in the motor evaluations between term infants at birth and LPI at the equivalent age.
Conclusion:: The LPI presented a gradual progression of motor development until the term-corrected age, but differences with term infants at birth were not detected.
