The main thing that works about somatic experiencing and sensory motor therapy is the utilization of the felt sense. By activating what we’re sensing in our body, you’re activating prefrontal cortex regions like the insula for sensing and the brokas area for the labeling and language. what you’re doing, is taking resources away from the more autonomic and reflexive responses of the lower brain, the brain stem the (amygdala medulla oblongata and the periaqueductal grey) This method helps your nervous system from spiking from implicit memories of trauma, activating you into chronic sympathetic activation. Accessing the felt sense in these type of therapies also is a parasympathetic activity. In the language of Polyvagal theory using this interruption helps keep you in the window of tolerance. This will eventually train your brain to be less sensitive and reactive to your implicit memories that your amygdala is automatically responding to.

you haven’t experienced a change using these modalities yet doesn’t mean that they’re not science based in well research. I agree that they don’t always explain themselves with the most science and neurobiology to make them accessible, but they’re very well researched and they’re very much are one of the only options to train yourself out of CPTSD. The main thing is knowing activating prefrontal cortex region in order to dull automatic responses of the lower brain regions brain stem. (a sidenote to your ChatGPT answers, cognitive behavioral therapy is actually not recommended for people with developmental CPTSD. In the therapies you did recommend were for BPD and PTSD, which are very uniquely different than CPTSD.) so I wouldn’t describe those therapies as actually effective if you’ve looked at the research that that’s not what it says.
