@ illuminatidinesh- The reason there is a confusion here- is because of when you first learnt these approaches of therapy- u learnt the current model of ndt which has incorporated the concept of motor control and motor learning (and therefore has a functional approach). My first exposure to therapy intervention was not based on the concepts of motor learning, but that of Neural maturation theory. Though it quickly moved on to Dynamic systems theory from there and currently it stays on models of motor control and learning. And thus it has required/aided a shift in intervention strategies, with every new step towards better understanding of how the normal human brain learns motor control.

I await a better understanding of how an abnormal/ injured infant nervous system learns and develops motor control....
