The hypothesis of this study is that early physical therapy intervention, initiated during the NICU stay and up to 2 months corrected age, based on the family-centered model, could promote preterm infants motor development in short-term (2 months corrected age) and long-term (8 months corrected age).

There is a high evidence level of different systematic reviews, which support the effectivity of early intervention with preterm infants.

The principal aim of this randomized controlled trial is to evaluate the effectiveness of early physiotherapy intervention to promote motor development in preterm infants at 2 and 8 months corrected age.

The secondary purpose is to study the motor development of those preterm infants who received early physical therapy intervention.
