I do somatic experiencing therapy, which was developed by Peter Levine. (I'm not very big into names though.) It's said that this therapy comes out of the same work he did, and is supposed to be a gentler version of it - which is hard to imagine with this video compared to videos of Somatic Experiencing. They seem quite similar in videos, except SE does not require certain exercise, and sometimes works on "defensive movements" that are stuck in the nervous system. Some triathletes I know use TRE after long workouts to work through tremors they get. From talking to my therapist, it's a little different with TRE for PTSD. She says it basically does the same thing as Somatic Experiencing, just a little more dramatic and in a little different way.
Here is an article that explains things very close to how my therapist describes what could happen with Somatic Experiencing and TRE.

"Is there an emotional response during the exercises?"
"While some people experience significant emotional release during the Trauma Release process, others may experience no emotional response whatsoever. Some may experience intense memories of a trauma, while others may have no memory or recollection at all while still achieving a significant physiological and psychological release."
"An enhancing attribute of the Trauma Release Exercise process is the physiological states associated with a trauma are often able to be released without having to actually relive, remember, or talk about the actual traumatic event itself."
"Some people who have experienced severe trauma may at times feel frightened during the exercises, not due to experiencing the tremors themselves, (which most people experience as mildly pleasurable) but occasionally due to the nature and intensity of the emotions surfacing that they are no longer able to control or suppress during the process."
"In such situations these people should be guided through the process with direct professional assistance being clearly informed that at any stage if they feel unsafe or uncomfortable the tremors can be immediately stopped by simply straightening the legs or rolling onto their side."
It's interesting stuff. If you try TRE, I hope it works for you and that you post more about your experiences with it. I'm quite curious myself about various kinds of somatic based therapies.
