What indicates that a preterm neonate's motor activity is typical?

In evaluating motor activity in preterm neonates, typical patterns can indicate the developing neurological and physiological processes associated with their gestational maturity. Tremors during quiet states can reflect the immature neurological control present in preterm infants. While tremors may seem concerning, they can actually be part of the typical neurological development process in neonates who are not yet fully matured and starting to regulate their motor functions.

In contrast, increased sleep duration is often seen in preterm infants but may not necessarily indicate typical or atypical motor activity. High muscle tone is more commonly associated with conditions such as hypertonia, which is not typical for preterm infants. Lastly, coordinated limb movements are typically seen in more mature infants and would not be expected in a preterm neonate, particularly one of very low gestational age. Thus, tremors during quiet states provide a clearer indication of immaturity while still aligning with typical patterns of motor activity development in preterm infants.
