Dynamic Systems Theory: A Primer for Pediatric Feeding Clinicians

Purpose: Dynamic systems theory (DST) is a theoretical framework that has been applied to motor learning with key clinical implications. DST is increasingly used as a framework for pediatric feeding research but is lesser known to clinicians reading and implementing the research. Clinical translation of DST is therefore critical and has not yet been undertaken for children with pediatric feeding disorder at the stage of solid foods. The purpose of this tutorial is to provide clinicians with an overview of DST so that they can understand and use DST principles in their clinical practice for children with pediatric feeding disorders. Conclusions: This tutorial focuses on introducing clinicians working with pediatric feeding clients to DST. To establish a foundational understanding, a clear definition of DST is offered, and its key tenets are described. Pediatric feeding specific examples are offered for each tenet to increase comprehensibility. DST is then used to describe the general process of development as well as the development of feeding behaviors and skills. Finally, clinical applications of DST for assessment and treatment of pediatric feeding disorders are discussed. DST is growing in its use in pediatric feeding research and is extendable to clinical practice. This tutorial emphasizes the dynamic nature of feeding development; the importance of holistic, family-centered care; and the potential for changes in clinical practices to better support families from this theoretical lens.
