Three approaches used to alter posture and movement abilities in infants and young children are compared and contrasted. Included are neurodevelopmental treatment (NDT) and developmentally based programming, the two most commonly used approaches in the United States, and conductive education, a Hungarian approach that is being adopted in countries throughout the world. Each of these approaches differs in terms of critical features such as the population focus or intervention methods used. An understanding of these approaches can assist therapists in beginning to address issues of best fit between intervention approaches and specific child characteristics.
