Characterization of the motor performance of newborns in a neonatal unit of tertiary level

Caracterização do desempenho motor de recém-nascidos em unidade neonatal de nível terciário

Summary

Objective:

To characterize the motor performance of newborns in a neonatal unit of tertiary level and compare the results to the values recommended by the Test of Infant Motor Performance (TIMP).

Method:

Newborns between 34 and 416/7 weeks of corrected gestational age, breathing spontaneously and presenting state of consciousness 4 or 5, according to Brazelton, were included. TIMP was used to evaluate the motor performance.

Results:

The age groups of 34-35 and 36-37 weeks showed on average TIMP scores similar to the reference values (p>0.05), while in the age groups of 38-39 weeks and 40-41 weeks TIMP scores were statistically lower than the reference values (p<0.001 and p=0.018, respectively). The 34-35 and 36-37 week groups were rated as average, while the 38-39 and 40-41 week groups were defined as low average. Classifications below average and very below average were not observed.

Conclusion:

The newborns showed average scores compared to the TIMP reference values; however, there were two groups whose performances were within the low average. There was no significant difference in motor performance of newborns in the age groups of 38-39 and 40-41 weeks. This behavior suggests that the sample studied has special features that possibly negatively influenced their motor performance. The results showed that the TIMP is a very useful tool and can be used safely in tertiary neonatal units.
