Somatic Experiencing attempts to promote awareness and release of physical tension that proponents believe remains in the body in the aftermath of trauma. They believe this occurs when the survival responses (which can take the form of orienting, fight, flight or "freeze") of the ANS are aroused, but are not fully discharged after the traumatic situation has passed. The details of this sequence are described in all the literature cited here, for example (p.92-97, 155-157, 158). (p.43-50). (p.38-40). (p.29-34). (p.273-277).
Somatic Experiencing uses procedural elements that have been said to work anecdotally, but have yet to be subjected to a double-blind study. The process involves a guided exploration of the nature and extent of the physical dysregulation that is harbored in the body as a result of trauma.
Techniques include "titration" of the client's experience. That is, in the initial steps of the procedure, barely perceptible changes in the body (a slight loosening of tension in the chest, for example) are attended to at length. (p.255). (p.xx). (p.170).
Another idea is that the client's experience should be "pendulated". (p.197-199, 205-206). (p.255). (p.xix, 64). 'Pendulation' refers to the movement between regulation and dysregulation. The client is helped to move to a state where he or she is believed to be somewhat dysregulated (i.e is aroused or frozen) and then helped to return to a state of regulation (loosely defined as not aroused or frozen). This process is done iteratively, with progressively more levels of dysregulation believed to be resolved by the client in successive pendulations.
"Resources" are defined phenomenologically as anything that helps the client's autonomic nervous system return to a regulated state. (p.xx, 63-79). In the face of arousal, "discharge" is facilitated to allow the client's body to return to a regulated state. Through this process the client's inherent capacity to self-regulate is believed to be restored. Somatic Experiencing is considered by its practitioners to be useful for two broad categories of trauma: shock trauma and developmental trauma. Shock trauma is loosely defined as a single-episode traumatic event such as a car accident, earthquake, battlefield incident, etc. Developmental trauma refers to various kinds of psychological damage that occur during child development when a child has insufficient attention from the primary caregivers, or an insufficiently nurturing relationship with the parent. (49-55, 138-139, 167-169, 227-231). (p.99-125).
