I have two adopted children and in the adoption world we have been looking at how to help people with trauma stuck in the body for about the last 25 years.
I have seen both Bruce Perry and Bessel van der Kalk speak at conferences.
The general advice seems to be that talking therapy helps if you have a therapist who makes you feel safe and contained - it doesnt matter what kind of therapy or if you like the therapist or enjoy it - it's the feeling of being safe/seen/hrld that matters.
But really you need somatic work too, which is where the body based stuff comes in.
EMDR is strongly recommended.
Also horse riding, dancing, movement in general, and drumming. They were always very keen on drumming.
I started doing tai chi and it was really wierd, but in the early days, when I did a move, I would get a flash of memory come flying up. Now, these weren't horrible memories - more like photographs from holidays. But it was like the specific movement released a memory. So you do have to be careful.
