Neural Exam - 3 month - prone position

From Embryology
This infant is almost 3 months old.
  • In the prone position, the baby is now able to bring his head up and look forward with the head being 45 to 90 degrees off the mat.
  • Weight is borne on the forearms.
  • When the head and chest are well off the mat, the baby is ready to start to roll from the prone to the supine position.
  • Rolling front to back usually occurs at 3 to 5 months of age.
  • Rolling over too early can be due to excessive extensor tone.
