Personally found EMDR to help in relation to traumatic or activating speaking situations really effectively. There’s a situation I would continuously struggle with, especially when it came to blocks, we worked on that with EMDR, and now it’s mostly easily. Many such examples, you can actually reduce that tension and activation in the body that happens in anticipation of the speaking event. I think stuttering and CPTSD is likely more linked than we even realise now. Not saying one causes the other but rather I think stuttering causes repeated sustained trauma leading to many symptoms within CPTSD.
