Somatic Experiencing (SE)
The trauma therapy developed by Peter A. Levine over ~45 years, given its theoretical statement in Payne, Levine & Crane-Godreau (2015). This is the wiki’s first named, trademarked, commercially-taught treatment (as opposed to a research paradigm or a broad approach like contemplative training).
What it is
A bottom-up, body-first psychotherapy for post-traumatic and chronic stress. Its defining commitment is that it directs attention to internal sensation — interoceptive (visceral) and proprioceptive/kinesthetic (musculoskeletal) — rather than to cognition, emotion-as-narrative, or the traumatic memory itself. It is explicitly not exposure therapy: it avoids intense evocation of the trauma and instead approaches it indirectly and in graded steps.
The therapy rests on the core-response-network theory of trauma (trauma as a reversible dysfunctional state of a subcortical dynamical system) and the biological-completion theory of change (completing a frozen defensive movement discharges the held activation). Its clinical grammar is a handful of named techniques:
- Resourcing — building embodied positive sensation and safety before touching trauma; grounded in attending to positive somatic markers rather than the negative cues traumatized clients fixate on, and in ventral-vagal social engagement (the therapist’s eye contact and voice).
- Titration — approaching charged material “drop by drop” to avoid flooding and re-traumatization.
- Pendulation — oscillating between activation (charge) and discharge (deactivation) so the system re-finds balance.
- Discharge — permitting the involuntary release (trembling, shaking, tears, the “voo” vocalization) that is claimed to trigger parasympathetic reset.
How it relates to the wiki’s other clinical interoception material
SE belongs on the same shelf as interoceptive-training-clinical, which already collects trauma, chronic pain, substance use and anorexia as cases of restoring tolerated access to interoceptive signals under skilled guidance — but SE is distinctive in two ways worth keeping separate:
- It takes a specific side in is-more-interoceptive-awareness-better. Not “more awareness,” but awareness steered toward safety signals first and titrated toward aversive ones only as tolerance builds. That is a more operational answer than most of the field-positions on that debate — it says which interoceptive contact, in what order — even if it is asserted clinically rather than tested.
- It defines itself against interoceptive-exposure. Where exposure sustains contact with the feared sensation to extinguish catastrophic appraisal, SE deliberately avoids sustained aversive contact and works instead through completion and discharge. SE claims this is faster, more robust to relapse, and less distressing — the sharpest live disagreement between two interoceptive trauma approaches the wiki holds.
The evidence problem, stated plainly
There is nothing in the evidence-base field because there is no evidence in the source. The originating paper is a theory paper by the therapy’s proprietors, illustrated by a composite case explicitly disclaimed as evidence, and it reports that no peer-reviewed SE studies existed at time of writing. This does not make SE wrong — biological-completion is a coherent and testable proposal — but it means the wiki files SE as a mechanism hypothesis with a clinical following and no outcome data, distinct in kind from the applications on interoceptive-training-clinical that at least cite feasibility studies. What would change the filing: an independent controlled outcome trial, and a direct test of the movement-specific completion claim. See payne-2015-somatic-experiencing.
