Somatic Experiencing: The Complete Guide to Peter Levine’s Trauma Therapy, the Evidence and the Costs

Somatic Experiencing (SE) is a body-focused trauma therapy developed by Peter Levine over some 50 years. A practitioner helps you notice physical sensations in small, paced steps, rather than retelling the event in detail, so that stress responses can settle. The research is promising but preliminary, and major PTSD guidelines do not recommend it first-line.

How we wrote this guide
We read the Somatic Experiencing International (SEI) website, including its training, tuition, trademark, research and international-organiser pages, and Peter Levine’s own biography and book pages. We read the clinical guidelines from the VA and Department of Defense, ISTSS, the World Health Organization and the American Psychological Association, and searched PubMed and Crossref for every SE trial and review we could find. We read each abstract, and the full text of the main randomised trial. We read the polyvagal-theory dispute in the original papers. Prices come from SEI and from practitioners’ own websites, checked in October 2026 and converted at 23 October 2026 exchange rates. Where evidence or a fact is missing, we say so. This guide is information, not medical or psychological advice.

Quick answer: does Somatic Experiencing work?

• Promising, not proven. The only randomised trial we found of SE for PTSD itself compared 33 people having SE with 30 on a waiting list and found large improvements (Brom et al., 2017). A later, larger Danish trial in people with back pain and PTSD symptoms found no added benefit (Andersen et al., 2020). No trial we found compares SE head-to-head with trauma-focused CBT or EMDR.
• Guidelines do not recommend it first-line. The American Psychological Association and the VA/DoD back trauma-focused CBT and EMDR. The VA/DoD says the evidence for SE is insufficient to recommend for or against.
• Costs vary widely. Single sessions in the listings we found run from about $90 to $200 (£65 to £150). Practitioner training in the US costs about $10,400 in tuition alone. The gentle self-practice in this guide is free.
• It is not an emergency service. For PTSD, dissociation, abuse or any crisis, see a licensed clinician. An “SEP” certificate is a training credential, not a licence.

What Is Somatic Experiencing?

Somatic Experiencing is a talking-and-noticing therapy that works through the body. “Somatic” means “of the body”. In a session, you and a practitioner pay attention to what you feel physically (tension, warmth, trembling, breath, an urge to move) while you talk. The practitioner paces the work so that you touch difficult material only briefly, then return to something steadier.

SE International (SEI), the non-profit that trains practitioners, says SE can “support the resolution of PTSD and developmental attachment trauma” (SEI, SE 101). Its central idea is that trauma is not only the event but an interrupted survival response. A threatened body prepares to fight or flee. If that is impossible, it can freeze, and the unfinished response, SE says, stays “stuck”. SE tries to let it complete, gently and in small doses.

Three features set it apart from most other trauma therapies:

• It does not require a detailed retelling. Levine’s team writes that SE “avoids asking clients to relive their traumatic experiences”. It approaches difficult sensations only after establishing sensations of safety and comfort (Payne et al., 2015).
• It is slow by design. Pacing, called titration, is the main safety tool.
• It is a trademarked, centrally trained method. SEI states that “Somatic Experiencing® and SE™ are trademarks owned by Peter A. Levine, PhD, or SE™ International”, and that SE may be taught only by SEP-certified people with written SEI approval (SEI, trademarks). That keeps teaching consistent. It also makes SE a commercial brand, which is worth remembering when reading SEI’s own claims.

SEI says it provides training directly or through affiliates in 40 countries (SEI, about us). The method is used in clinics, private practices, humanitarian settings and by physiotherapists, bodyworkers and coaches who have completed the training.

Peter Levine: Background and Origins

Peter Levine developed SE, and almost everything public about his life comes from him or his organisation. We separate what is documented from what rests on his account.

What His Own Biography Says

Levine’s website says he holds a doctorate in biophysics from the University of California, Berkeley, and one in psychology from International University, and that he has developed SE “over the past 50 years” (Levine, About Peter). He writes that in 1978 he met Stephen Porges, originator of polyvagal theory.

He is open about the personal side: “much of my research was ‘me-search.'” His autobiography, published by Inner Traditions, says he helped thousands of others “before resolving his own trauma years later with the support of his method” (Inner Traditions). That candour is valuable. It also means SE grew out of one man’s attempt to heal himself.

The Tiger Story

SEI tells the founding story this way. A client it calls “Nancy” froze in a session and relived a childhood surgery in which she was restrained and given ether. Levine, SEI says, had a sudden vision of a charging tiger and told her: “Nancy, you’re being chased by a tiger. Run! Run for the nearest tree!” As she began kicking her legs, her body appeared to complete a response that had been frozen (SEI, SE 101). The story gave his best-known book, Waking the Tiger, its title.

This is a single case, told by its protagonist. It illustrates the idea and is no evidence for it.

From Observation to Organisation

Levine’s theory also rests on an observation about animals: that wild animals face constant threat without developing trauma because they shake, tremble and breathe deeply after an escape, “discharging” the arousal. His own paper is frank about the source. It says the phenomena “have been observed repeatedly by one of the authors (PAL) over 45 years of clinical experience, and confirmed through numerous anecdotal accounts by those who work professionally with wild animals”, and that the authors “have not been able to find any significant treatment of these phenomena in the peer-reviewed literature” (Payne et al., 2015).

Levine’s site says his work “has been taught to over 30,000 healers in over 42 countries”, while SEI says 40 countries. Both are organisational claims, not audited counts (SEI, global impact).

The Core Ideas

SE has a small vocabulary, and each term is a practical instruction as well as a theory. Below, we say what each means in a session and how well it is supported.

Trauma as an Incomplete Defensive Response

SE’s founding claim is that traumatic stress persists because a defensive response was blocked. SEI says it rests on Levine’s observation that animals do not show trauma symptoms, and that the frozen state needs to be “discharged, through shakes and trembling” (SEI, SE 101). In humans, Levine and colleagues write, things such as fear of the discharge process and “cortical interference” can stop that “resetting” (Payne et al., 2015).

This is a model, and a useful way for some people to understand their reactions. It is not an established mechanism. Mainstream research explains PTSD mainly through learning, memory, threat appraisal and avoidance, and has not directly tested SE’s “unfinished response” idea.

Sensation, Image, Behaviour, Affect, Meaning (SIBAM)

SE trainings teach a five-channel map of experience: Sensation, Image, Behaviour, Affect and Meaning (SEI, professional training). The practitioner tracks which channels are active, and much of the early work is helping you register body sensation, which SE treats as the doorway to the rest.

Titration

Titration, borrowed from chemistry, means approaching distress in very small amounts. The Israeli trial describes it as “how to keep arousal at a low level during the processing of traumatic triggers” (Brom et al., 2017). A practitioner may ask you to notice a faint trace of a sensation for a few seconds, then stop. We found no study testing whether SE’s pacing beats other approaches.

Pendulation

Pendulation is the movement back and forth between a difficult sensation and a steadier one. You might notice tightness in your chest, shift attention to your feet on the floor, then return. The idea is that this teaches your system that discomfort rises and falls instead of staying put.

Resourcing

A resource is anything that evokes a felt sense of safety or strength: a person, a place, a pet, the support of a chair. Payne and colleagues describe resources as “embodied experiences of positive feeling”, not “abstract mental states of well-being”. SE usually builds resources before touching painful material, and returns to them when you become overwhelmed.

Discharge

Discharge is the visible release of aroused energy: trembling, heat, deep breaths, yawning, tears, tingling, or an urge to push or run. SE treats these as signs of the nervous system settling and lets them happen at their own pace. This is the most contested idea in SE. There is no direct evidence that discharge is the active ingredient of therapy, or that it means trauma is resolving rather than ordinary arousal changing.

The Window of Tolerance

The “window of tolerance” is the range of arousal in which you can think, feel and function. Above it, you may feel panicky or flooded (hyperarousal). Below it, you may feel numb or shut down (hypoarousal). The term is usually credited to the psychiatrist Daniel Siegel, and trauma therapists, including SE practitioners, aim to work inside the window (Corrigan et al., 2011). It is a metaphor, not a measured quantity.

What a Session Looks Like

A session is mostly conversation with pauses, not a procedure. There is no fixed script, but the published trials and practitioner pages describe a recognisable shape.

Before you start. A good practitioner will ask what brings you, what support you have, and whether you are in treatment elsewhere. In the Israeli trial, the first sessions were “dedicated to learning about SE and building therapist–client rapport” before any trauma work (Brom et al., 2017). SE does not require a detailed account of what happened, so you can decide how much to share.

During a session. You will usually be seated. The practitioner asks you to notice what is happening in your body as you speak (“Where do you feel that?”). They may invite you to look around the room slowly (orienting), to feel your feet or seat (grounding), or to recall something that feels good (resourcing). When something stronger arises, they slow down, and you may move between the difficult and the steadier sensation.

Touch. Some practitioners offer touch, such as a hand on the shoulder or back. SEI’s training covers “the appropriate use of touch” (SEI, professional training). Touch is optional. You can decline it or ask them to describe it first. If you have a history of abuse, say so.

Length and number. Individual sessions in the listings we found last 50 to 90 minutes. The main trial used 15 weekly sessions; the Danish back-pain trials used six to twelve (Andersen et al., 2017).

Online. Many practitioners offer online sessions, so you can work with someone in another country, subject to the licensing rules below.

Becoming a Somatic Experiencing Practitioner (SEP)

SEP training takes about three years, and costs roughly $10,000 to $14,500 in tuition alone, depending on the country. Knowing how it works helps when choosing a practitioner.

Structure. SEI’s US programme has eight modules over about two and a half to three years, taken in sequence: three four-day Beginning modules, three four-day Intermediate modules and two six-day Advanced modules (SEI, professional training). SEI’s graduation requirements list 216 contact hours in total (SEI, graduation requirements). Other countries differ: an Australian organiser runs six six-day modules (Restoring Resilience).

Certification. To earn the SEP certificate, you must also complete 12 hours of personal SE sessions and 18 credit hours of case consultation (SEI, graduation requirements).

Cost. US tuition is $1,180 per Beginning or Intermediate module and $1,650 per Advanced module. Eight modules come to 10, 380(9,980 if paid early) (SEI, tuition and support). In Australia, one organiser charges AU19, 200toAU20,700 plus GST for the three years, per its 2024 rates (Restoring Resilience). Travel, lodging, personal sessions and consultation are extra. We could not read current UK or India fee tables, so ask the local organiser.

Who can train. Training is open to people with “an active professional practice”: clinicians, bodyworkers, and others including “first responders, crisis center staff, educators, mediators, clergy, chaplains, coaches” (SEI, prospective students).

What SEP does and does not mean. SEI calls itself “not a regulatory or licensing entity”, and tells students they “are responsible for operating within their professional scope of practice” (SEI, prospective students). The certificate shows someone completed SEI’s training. It does not by itself license anyone to diagnose or treat PTSD, and a directory listing is not an assessment of quality. SEI’s code of ethics and grievance process cover its US-based trainings (SEI, ethics).

A Safe Exercise: Orienting, Grounding and Resourcing

The only parts of SE we think are reasonable to try alone are the gentlest: looking around, feeling the ground, and recalling something calming. We have left out discharge or shaking work, revisiting memories, and touch. Those are what the training is for.

An honest caveat first. We found no study of SE-style orienting and resourcing as a self-guided exercise, so we cannot say how well it works or how safe it is. Attention to the body can unsettle some people. A systematic review of meditation studies found adverse events in 8.3% of participants overall, including in people with no history of mental health problems (Farias et al., 2020). That is a different practice, but the lesson transfers. A paper co-written by Levine says a disturbing experience can arise “too intensely or too quickly”, and “temporarily diverting awareness to a positive, safe experience, such as the support of the ground or positive imagery” can restore balance (Payne et al., 2015). This exercise is built on that idea.

Before You Start

• Talk to a clinician first if you have PTSD or complex PTSD, flashbacks, dissociation (feeling unreal, detached or “gone”), thoughts of self-harm, or are in an unsafe situation. In those cases, do this only if your therapist suggests it.
• Choose a safe place. Sit or stand, eyes open, for five to ten minutes. Plain orienting is enough.
• You can stop at any point. Stopping early is not failing.

How to Practise Orienting, Grounding and Resourcing

1. Settle. Sit comfortably, with your feet on the floor if you can. Breathe out slowly, without forcing it, then let your breathing find its own rhythm.
2. Orient. Let your eyes move slowly around the room, turning your head too. Notice colours, shapes, light and anything neutral or pleasant. Name a few quietly (“grey chair, green plant, window”).
3. Ground. Notice where your body touches the chair, floor or wall. Feel the weight of your legs and feet. If you like, press your feet gently into the floor, then let go.
4. Find a resource. Bring to mind something calm that is not tied to anything painful: a place you like, a pet, a friend. Notice, without hurrying, whether anywhere in your body responds (a softening, warmth, easier breath). It is fine if nothing happens.
5. Stay a little. If you notice an easy sensation, rest your attention there for about a minute. If you notice tension or unease, move your attention back to the room or your feet instead.
6. Come back and stop. Look around once more, move your hands or feet, and take a sip of water. Notice how you feel compared with when you started, then finish.

Stop Rules

Stop, orient to the room, and consider talking to a professional if:

• You feel panicky, numb, unreal or “far away”.
• A memory or image comes up that you cannot easily set down.
• Your body feels worse (tight chest, unwelcome shaking, nausea) rather than steadier.
• The exercise leaves you worse for more than a day.

If you are in distress, stop and speak to a doctor or licensed therapist. Never push through these signs.

How It Relates to Polyvagal Theory, EMDR and Trauma-Focused CBT

SE sits alongside other trauma approaches rather than replacing them. Polyvagal theory supplies some of SE’s language. EMDR and trauma-focused CBT are the therapies that guidelines recommend.

Polyvagal Theory: A Close Relative With a Contested Foundation

Stephen Porges introduced polyvagal theory in 1995 (Porges, 1995). It proposes that the two main pathways of the vagus nerve serve different roles in safety, defence and social connection (Porges, 2009). Beginning-level SE training aims to “begin to integrate Porges’ Polyvagal Theory of ANS function” (SEI, professional training).

The theory is now sharply disputed. The physiologist Paul Grossman argued in 2007 that it “does not accurately depict evolution of vagal control of heart-rate variability” (Grossman & Taylor, 2007), and in 2023 that each of its five basic premises is “untenable or highly implausible” (Grossman, 2023). In 2026, Grossman and 38 co-authors from physiology, neuroscience and evolutionary biology published “Why the polyvagal theory is untenable” (Grossman et al., 2026). They single out “dorsal vagal shutdown”, saying freezing and dissociation do not typically cause “massive” or “lethal” slowing of heart rate. Porges replied in the same journal that the critique “repeatedly evaluates a reconstructed proxy of the theory”, and defended it as a “systems-level” framework (Porges, 2026).

What does this mean for SE? SE’s practical tools (pacing, orienting, resourcing) do not depend on whether the vagus nerve works as polyvagal theory says. They could help, or not, for other reasons. But SE’s explanations, with talk of “ventral vagal” safety and “dorsal” shutdown, lean on a theory many physiologists reject, so treat anatomical-sounding explanations of your own body with caution. We cannot settle this dispute: each side is confident the other is wrong.

EMDR

Francine Shapiro introduced eye movement desensitisation and reprocessing in 1989 (Shapiro, 1989). The client holds a target memory in mind while following bilateral stimulation, usually eye movements. The WHO notes that EMDR, unlike trauma-focused CBT, “does not involve detailed descriptions of the event” (WHO, 2013).

SE and EMDR both avoid a detailed account and attend to body sensation. EMDR, though, works on specific target memories with a manualised protocol and has many randomised trials. SE is less structured and has far fewer.

Trauma-Focused CBT

Trauma-focused CBT is the family that includes cognitive processing therapy, prolonged exposure and narrative exposure therapy. It has the most evidence: a 2020 review of 114 randomised trials with 8,171 participants concluded that trauma-focused CBT and EMDR have “robust” evidence and should be first-line (Lewis et al., 2020).

Trauma-focused CBT also teaches arousal-management skills, so regulation is not unique to SE. The big difference is that it asks you to process memories directly, which many people find hard and SE avoids. A qualitative study of 30 veterans in a trial comparing prolonged exposure with SE found that SE participants described “learning a language” they could apply elsewhere (Harwood-Gross et al., 2025). That paper reports experiences, not outcomes.

How They Compare

The practical question is what the guidelines recommend for your condition, and what you tolerate. Tell any practitioner what else you are doing.

Does Somatic Experiencing Work? The Evidence, Honestly

SE has a small, promising body of research and no head-to-head evidence against first-line treatments. One trial found a clear effect on PTSD symptoms, one found a modest effect, and a larger one found nothing extra. The rest is uncontrolled, qualitative or about trainees. SEI itself says: “In the near future, it may be possible for SE to achieve evidence-based status” (SEI, research).

Evidence at a Glance

The Strongest Study: Brom et al., 2017

The Israeli trial was, in its authors’ words, “the first known randomized controlled study” of SE for PTSD. Sixty-three adults meeting full DSM-IV-TR criteria were randomised to 15 weekly SE sessions or a waiting list; the waitlist group then received SE too. PTSD severity and depression improved significantly more in the SE group (Brom et al., 2017).

These are strong results, but a waitlist control shows only that SE beats doing nothing for 15 weeks, not that it beats another therapy or equal supportive attention. The authors acknowledge “no measure of the behavioral adherence to the protocol”, and that the study “does not give us information about the comparison with other treatment modalities”. They also note that “the clinical results should be considered moderate”: 44.1% of the sample lost the PTSD diagnosis. About 10% of participants were missing at the controlled comparison and 21.7% at the final assessment. The clinical assessors were blind to group. One trial is not a replication, and we found no second controlled trial of SE for diagnosed PTSD.

The Back-Pain Trials: One Positive, One Null

A Danish team ran two trials in people with chronic low back pain and PTSD symptoms. In the 2017 trial (91 people), adding six to twelve SE sessions to usual care reduced PTSD symptoms and fear of movement more than usual care alone, but its authors concluded that “the overall effect of SE was less than expected and the clinical importance of the effects can be questioned” (Andersen et al., 2017). The larger 2020 trial (114 people) compared SE plus physiotherapy with physiotherapy alone and found “no significant group differences … on any of the outcomes at any timepoints” (Andersen et al., 2020).

Field Studies and Training Studies

After the 2004 tsunami, two uncontrolled studies gave survivors one or two SE sessions. In southern India, 90% of the 150 people who completed follow-up reported significant improvement or no symptoms (Parker et al., 2008). In Thailand, 67% of 53 people reported complete or partial improvement straight after a session (Leitch, 2007).

A 2018 study of 18 SE trainees found self-reported falls in anxiety and somatic symptoms over training (Winblad et al., 2018). It studied clinicians, not clients, without a control group.

Reviews and Ongoing Trials

A 2021 scoping review found 83 articles and analysed 16. It called the results “promising” but in need of “more support from unbiased RCT-research”, with study quality “mixed” (Kuhfuß et al., 2021). A randomised trial comparing SE with prolonged exposure in veterans has published only a qualitative paper on participants’ experiences (Harwood-Gross et al., 2025). We found no outcome results from it.

What the Guidelines Say

No major PTSD guideline lists SE as a first-line treatment.

• American Psychological Association (US, 2017): strongly recommends CBT, cognitive processing therapy, cognitive therapy and prolonged exposure, and suggests brief eclectic psychotherapy, EMDR and narrative exposure therapy. SE is not mentioned (APA, 2017). We could not load the live APA page, so we read a text copy.
• VA and Department of Defense (US, 2023): recommends cognitive processing therapy, prolonged exposure or EMDR. It lists SE among mind-body interventions (recommendation 27) for which there is “insufficient evidence to recommend for or against”, and rates the Work Group’s confidence in that evidence as “very low” (VA/DoD, 2023).
• ISTSS (international, 2018): classes SE as an “intervention with emerging evidence” for adults, based on one study of 60 people (SMD −0.75, 95% CI −1.28 to −0.22) with evidence rated “very uncertain” (ISTSS evidence summary). The main recommendations are in the ISTSS guidelines.
• World Health Organization (2013): says trauma-focused CBT, EMDR or stress management “should be considered” for adults with PTSD (WHO, 2013). A 2013 Cochrane review of 70 trials found trauma-focused treatments more effective than non-trauma-focused ones for chronic PTSD (Bisson et al., 2013). SE was not among the therapies it covered.

How to Read This Evidence

• “Promising” means “worth testing more”, not “works”. The early trials used waitlist or usual-care comparisons, the weakest tests.
• Absence from guidelines is not a verdict. SE is left out for lack of evidence, not proven lack of benefit.
• Active comparison is the missing piece. No trial pits SE against trauma-focused CBT or EMDR.
• Some researchers are connected to the method. All the therapists in Brom’s trial were SE-certified, and Levine co-wrote the main paper on SE’s mechanisms (Payne et al., 2015). Independent replication matters.

Criticisms and Risks

The main criticisms concern thin evidence, borrowed science and a commercial structure. We found no study that systematically measured SE’s harms, so we cannot say how common they are. In the main trial, five people in the SE group dropped out, four after one or two sessions, though the authors believe the reasons were personal (Brom et al., 2017).

• The evidence is thin, and promoted ahead of itself. SEI’s research page calls SE “a leading best practice for healing trauma” in the same paragraph that admits it “may be possible” in future to reach evidence-based status (SEI, research). A 2026 commentary on body-based trauma claims says such studies “often face methodological limitations, including small sample sizes, lack of active control conditions and inconsistent follow-up data”, and that none has shown superiority to CBT (Scheeringa, 2026). It targets The Body Keeps the Score, not SE.
• The founding animal story is anecdotal, as Levine’s own paper says, and the explanatory science is contested (see the polyvagal dispute above).
• “SEP” is a training certificate, not a licence. Training is open to coaches and bodyworkers as well as clinicians, and SEI is “not a regulatory or licensing entity”.
• It is a commercial brand. The name is trademarked and training is controlled centrally. SEI’s own claims come from a body with a stake in them.

Practical risks follow from these:

• Delay. If SE replaces a guideline-recommended therapy for PTSD, you may wait longer for the treatment with the strongest evidence.
• Activation. Attention to body sensation can raise distress, particularly after severe or repeated trauma. Pacing is meant to prevent this, but depends on the practitioner’s skill.
• Touch. Touch is a recognised part of SE (Kuhfuß et al., 2021). You can always decline it, and a good practitioner asks first.

How Much Does Somatic Experiencing Cost?

Sessions in the listings we found cost about $90 to $200 (£65 to £150) each; the self-practice in this guide is free. Prices come from practitioners’ own websites, checked in October 2026 and converted at 23 October 2026 European Central Bank rates (Frankfurter). They are examples, not an average.

What the Prices Mean

• Who sets the price matters. Some rows are coaches or bodyworkers, and the London row is a registered psychotherapist. The SEP certificate does not tell you which.
• Insurance rarely helps. Two German practitioners say statutory insurers do not usually cover SE, a Brisbane practitioner says Medicare mental health plan rebates do not apply to her sessions, and one page says SE is “not currently covered by insurance” (example). Ask before booking.
• India. We could not verify an Indian session price or a current Indian training fee, so we do not quote one.

How to Find a Practitioner, Wherever You Live

Start with SEI’s directory, then check the person’s licence, not just their SEP certificate. SEI lists practitioners in its Find a Practitioner directory. We could not test its filters because the page loads dynamically, so check each listing’s country and whether online sessions are offered.

Where to Look

• Worldwide: the SEI directory above, and SEI’s list of international organisers by region (the Americas, Europe, the Middle East and Africa, and Asia-Pacific) (SEI, international organisers).
• Europe: the European Association of Somatic Experiencing links national associations.
• UK: SEA UK has a directory. It states that it “neither endorses nor recommends the practitioners or participants listed”.

Questions to Ask Before You Book

1. What is your licence or registration, and which regulator or professional body holds it? Ask for a number you can check.
2. Have you worked with my situation, and will you refer me for a first-line therapy if needed?
3. Do you use touch, and how do you ask consent?
4. What happens if I feel overwhelmed in a session?
5. What does it cost in total, including cancellations?

Rules Differ by Country

Whether a practitioner needs a licence depends on the title and the country. Examples:

• United Kingdom. The Health and Care Professions Council protects specific practitioner-psychologist titles, but “counsellor”, “psychotherapist” and “therapist” are not (HCPC). Voluntary registers such as the BACP exist.
• United States. Counsellors and therapists are licensed state by state (American Counseling Association). The APA has advice on finding a therapist.
• Canada. In Ontario, “psychotherapist” is a protected title and “counsellor” is not (CRPO). Rules vary by province.
• Australia. “Psychologist” is a protected title (AHPRA), whereas counsellors are mostly self-regulated through bodies such as PACFA.
• India. Clinical psychologists are registered with the Rehabilitation Council of India.

An SEP with no other licence is often working outside regulated psychotherapy, so a regulator may not handle a complaint. This is not legal advice.

Frequently Asked Questions About Somatic Experiencing

What is Somatic Experiencing?

Somatic Experiencing (SE) is a body-focused trauma therapy developed by Peter Levine. A practitioner helps you notice physical sensations in small, paced steps, rather than retelling events. Its central idea is that trauma is an interrupted survival response. The research is promising but preliminary, and guidelines do not recommend it first-line.

Does Somatic Experiencing work for PTSD?

The evidence is promising but limited. One randomised trial of 63 adults with PTSD found large improvements against a waiting list, but none we found compares SE with trauma-focused CBT or EMDR, and a larger back-pain trial found no added benefit. It is worth testing further, not proven.

Is Somatic Experiencing recommended by clinical guidelines?

No major PTSD guideline recommends it first-line. The APA does not mention it, and the VA and Department of Defense say there is insufficient evidence for or against. ISTSS classes it as having “emerging evidence”. Ask a clinician which therapies are recommended for you.

How much does a session cost?

In the listings we found, a session cost roughly $90 to $200 (£65 to £150), depending on country, session length and the practitioner’s background. Insurance rarely pays. The exercise in this guide is free.

Is a Somatic Experiencing practitioner a licensed therapist?

Not necessarily. “SEP” is a certificate from SE International, which says it is “not a regulatory or licensing entity”. An SEP may be a psychotherapist, physiotherapist, bodyworker or coach. Ask what licence they hold and with which regulator, because licensing rules differ by country and state.

How is Somatic Experiencing different from EMDR and trauma-focused CBT?

SE starts with body sensation and does not require detailed retelling. EMDR targets specific memories with bilateral stimulation, and trauma-focused CBT processes memories and meanings. Both are structured, usually 8 to 12 sessions, and have far more trial evidence. Some people use SE alongside them.

Can I practise Somatic Experiencing on my own safely?

Only the gentlest parts. Looking around the room, feeling the ground and recalling something calming are low-risk for most people, though untested as a solo exercise. Skip discharge, memory and touch work, stop if you feel worse, and see a clinician first if you have PTSD.

Key Takeaways

• The evidence is promising, not proven. One positive waitlist trial, mixed back-pain trials, no head-to-head comparison.
• Guidelines do not recommend it first-line. The APA, the VA/DoD and the WHO favour trauma-focused CBT and EMDR.
• “SEP” is a certificate, not a licence. Check their regulated qualification.
• Costs vary. Sessions run about $90 to $200, and training about $10,000 to $14,500.
• For PTSD, dissociation, abuse or crisis, see a licensed clinician, wherever you live.
