The Polyvagal Theory really took the world 'by storm' over the last few years. I first heard it mentioned at an ICPA seminar in 2010 or so, and published the first ever chiropractic and polyvagal paper a few years later (http://bit.ly/2yxfNxN). Now it is everywhere and most parents of kiddos with Autism have heard of it. Originally released in 2023, recorded live at The Wave at Life West.
