I recently attended Stephen Porgues workshop in Ottawa called Social Connectedness as a Biological Imperative: Understanding Trauma through the eyes of Polyvagal Theory. If anyone is interested in pursuing a specialization in trauma or expanding their trauma learning repertoire, I highly recommend attending a workshop with Stephen Porgues. He is a great speaker that can break down the science of Polyvagal Theory so that you can apply this knowledge to helping your trauma clients. It was a very informative and even inspiring workshop to attend. I cannot say all workshops in the past have given me more fuel for the passionate work that I feel I am doing. I thought I would share some insights and learning points that I took away from this workshop. By all means, it would be wise to look into Polyvagal Theory in its entirety to full understand its scope and application for treatment. I will not be going into it in full as that would take up a lot of blog space and it is not the purpose I intend on in my blog. I recommend either attending a workshop or purchasing Stephen Porgues book on Polyvagal Theory.
First of all, Polyvagal Theory specifies two functionally distinct brances of the vagus nerve, the tenth cranial nerve, that serve different evolutionary stress in mammals, including us humans. The less evolved vagus nerve branch serves as a more primitive branch that illicits immobilization behaviors (ie feigning death) whereas the more evolved vagus branch is linked to social communication and self soothing behaviors (wikipedia). You can check out YouTube for more explanations on Polyvagal Theory – here’s another brief definition in relation to trauma https://www.youtube.com/watch?v=8RKC3Ga6shs Polyvagal Theory claims that the nervous system employs a hierarchy of strategies to both regulate itself and to keep us safe in the face of danger. In fact, it’s all about staying safe. Our highest Strategy involves social engagement which is regulated by the myelinated vagus nerve. Our next strategy is fight or flight, regulated by the sympathetic nervous system when social engagement is not an option. Our last option is to freeze, to immobilize when fight/flight is not an option in the face of trauma(Garland, 2013). Continue reading
