Neurological examination in the healthy term newborn.

We carried out a cross-sectional study with a sample of 106 normal full-term newborns examined within 24 to 72 hours of birth. The following findings were evaluated: head and chest measurements, muscle strength, tone, tendon reflexes, superficial reflexes, primitive reflexes, and cranial nerves. All 106 newborns were considered neurologically normal. We found no differences in the neurological examination findings for newborns with different gestational ages. Primitive reflexes and appendicular tone in newborns examined at earlier postnatal ages tended to be less intense. We were able to determine the prevalence of certain neurological examination findings for the normal newborn and to discuss some differences between our results and those of other studies. Prevalence estimations for the different findings in our study may be valid for different populations as long as the same methodology is adopted.
