Somatic Experiencing vs. Pain Reprocessing Therapy (PRT) for Chronic Pain: How They Differ and What the Evidence Shows

‍Two body-focused therapies get compared constantly, but they were built for different problems. Here's what each one does, what the research supports, and how to think about which fits your situation.

If you've been researching non-drug approaches to chronic pain, you've likely come across both Somatic Experiencing (SE) and Pain Reprocessing Therapy (PRT). Both work with body sensations. Both talk about the nervous system. And both are frequently recommended in chronic pain communities, often interchangeably.

They are not interchangeable. Somatic Experiencing is a trauma therapy that has been studied mainly for post-traumatic stress. PRT is a pain treatment, developed specifically to help the brain unlearn chronic pain, and it has direct randomized-trial evidence in chronic back pain, with results that held up over five years. Understanding that difference matters when you're deciding where to put your time, money, and hope.

At a Glance

• Somatic Experiencing is a body-based trauma therapy; PRT is a pain-specific treatment that retrains how the brain interprets pain signals.
• In a randomized trial of adults with chronic back pain, 66% who received PRT were pain-free or nearly so after four weeks, with benefits lasting five years.
• In two trials of adults with back pain and post-traumatic stress symptoms, SE improved trauma symptoms and fear of movement, but did not reduce pain more than standard care.
• Somatic tracking, a core PRT technique, is often confused with Somatic Experiencing. The names are similar; the methods and goals are different.
• Lin Health's coach-led program is based on findings from PRT and related neuroplastic pain research, and is covered by most insurance plans in CO, TX, FL, CA, and NY.

Why These Two Therapies Get Compared

Chronic pain, generally defined as pain lasting more than three months, affects 24.3% of US adults according to the CDC's National Center for Health Statistics. For a large subset of these people, pain persists after tissues have healed, or exists without a clear structural cause. Researchers call this nociplastic pain: pain generated by altered processing in the nervous system rather than by ongoing tissue damage.

Both SE and PRT emerged from this same insight, that the brain and nervous system play a central role in persistent symptoms. Both ask you to pay attention to body sensations instead of avoiding them. That surface similarity is why they get compared. The difference is in what each therapy targets and what the evidence actually supports.

What Is Somatic Experiencing?

Somatic Experiencing was developed by Peter Levine, PhD, as a treatment for trauma. The core idea is that traumatic experiences can leave survival responses (fight, flight, freeze) incomplete and stuck in the body, and that guided attention to internal body sensations can help the nervous system discharge that stuck activation and return to regulation.

How SE Sessions Work

An SE practitioner guides you to notice physical sensations connected to a stressful or traumatic memory, in small, manageable doses. Two techniques define the approach:

• Titration: approaching difficult sensations gradually, a little at a time, keeping the nervous system within a manageable range
• Pendulation: moving attention back and forth between distressing sensations and sensations of safety or comfort

SE is typically delivered one-on-one, and courses in research settings have run 6 to 12 sessions.

What SE Targets

SE targets trauma responses, not pain directly. When SE is offered to people with chronic pain, the reasoning is that unresolved trauma may be keeping the nervous system in a threat state that amplifies symptoms. That reasoning has some grounding: research suggests that roughly 1 in 10 people seeking care for chronic pain also meets criteria for PTSD, with higher rates in chronic widespread pain.

What Is Pain Reprocessing Therapy?

PRT was developed by therapist Alan Gordon and colleagues as a direct treatment for chronic primary pain, pain that persists because of learned brain pathways rather than tissue damage. The goal is for you to genuinely re-interpret the pain itself: to experience it as a false alarm from the brain rather than a sign of bodily harm.

How PRT Sessions Work

In the published trial protocol, PRT began with a medical evaluation to rule out structural causes, followed by eight sessions over four weeks. Sessions combine:

• Pain neuroscience education: building the case, from your own history and imaging, that the pain is brain-generated and reversible
• Somatic tracking: attending to pain sensations with curiosity and a sense of safety, rather than fear
• Exposure and positive-affect work: gradually returning to feared movements and situations

You can preview the approach in Lin Health's PRT crash course.

Somatic Tracking Is Not Somatic Experiencing

This is the single biggest source of confusion between the two therapies. Somatic tracking is one technique inside PRT: you observe the pain sensation itself through a lens of safety, to teach the brain that the signal is not dangerous. Somatic Experiencing is an entire trauma therapy: you attend to body sensations connected to traumatic memories, to complete stuck survival responses. Similar names, different targets, different bodies of evidence.

What the Research Shows

The Evidence for PRT

PRT's back-pain results stand out in a field where treatment effects are usually modest. In a randomized trial of 151 adults with chronic back pain, 66% of participants who received PRT reported being pain-free or nearly pain-free after four weeks of treatment, compared with 20% who received an open-label placebo injection and 10% who continued usual care. Gains were largely maintained at one year, and Lin Health's research library includes a summary of the trial.

The durability finding is unusual for any chronic pain treatment. At five-year follow-up, 55% of PRT participants remained nearly or completely pain-free, with average pain intensity about 1.9 out of 10, and lasting advantages in pain interference, depression, and fear of movement.

The newest evidence is a head-to-head comparison reported in a 2026 conference abstract: 150 adults with chronic back pain were randomized to PRT, cognitive behavioral therapy (CBT), or usual care. Average pain intensity fell 59% with PRT, versus 22% with CBT and 8% with usual care, this time in a more racially diverse sample treated by clinicians who were not PRT's developers. The full peer-reviewed paper has not yet been published, so these results are promising rather than final. Interviews with earlier trial participants describe what recovery felt like in the patients' own words.

Two honest caveats. The strongest PRT evidence is in chronic back pain specifically, in adults whose pain was primary (not caused by identifiable tissue damage). For other conditions, such as fibromyalgia, PRT research is still preliminary: an early uncontrolled pilot showed encouraging symptom reductions, but no randomized fibromyalgia trial has been completed.

The Evidence for SE

SE's research base looks very different. A review of SE research found preliminary evidence that SE reduces PTSD symptoms and improves well-being, while noting that few rigorous randomized trials exist.

For chronic pain specifically, the evidence comes mainly from two Danish randomized trials in people with low back pain and co-occurring post-traumatic stress symptoms. In the first, adding brief SE to usual spine care reduced PTSD symptoms and fear of movement, but pain and disability improved about the same in both groups. In the second, larger trial, adding up to 12 SE sessions to physiotherapy produced no additional benefit on pain-related disability, pain intensity, or trauma symptoms compared with physiotherapy alone.

In plain terms: in the populations studied so far, SE has helped some trauma-related outcomes but has not been shown to reduce chronic pain beyond standard care. That does not mean SE is worthless for people in pain. It means that if pain reduction is your primary goal, SE's evidence is indirect, while PRT's is direct.

Side-by-Side Comparison

Which Approach Fits Your Situation?

There's no head-to-head trial of SE versus PRT, so no one can tell you with certainty which would work better for you. The existing evidence suggests a practical way to think about it:

• If chronic pain is your main problem, especially back pain that has outlasted healing or lacks a clear structural explanation, PRT has the most direct evidence for pain reduction of the two.
• If unresolved trauma is prominent, and PTSD symptoms like hypervigilance, nightmares, or flashbacks sit alongside your pain, a trauma-focused therapy may be a valuable part of care. Evidence-based PTSD treatments should be discussed with a licensed clinician; SE is one body-oriented option with preliminary support.
• The two are not mutually exclusive. Trauma and chronic pain frequently co-occur and can reinforce each other. Some people work on both, either in sequence or in parallel, and PRT itself includes gentle somatic practices that many trauma-aware patients find accessible.

Whichever direction you lean, a medical evaluation comes first. Reattribution-based approaches like PRT are designed for pain that is primary, meaning a clinician has ruled out fractures, tumors, infections, inflammatory disease, and other structural causes that need different treatment.

How Lin Health Helps with Chronic Pain

Lin Health's program is built on the same body of research that produced PRT. The core idea, supported by research on how pain becomes chronic, is that after tissues heal, the pain alarm can get stuck in the nervous system, firing without danger. Retraining that alarm is a skill, and it's easier with a guide.

Here's what the program looks like:

• A dedicated recovery coach, trained in pain-specific behavioral methods, who meets with you weekly by video and stays available by chat between sessions
• Multiple modalities in one place: CBT, ACT, emotional awareness and expression work, and somatic tracking, drawn from the same research tradition as PRT and tailored to your condition
• An app with structured modules covering pain neuroscience education and daily practice
• Insurance coverage and short wait times: most patients in Colorado, Texas, Florida, California, and New York pay nothing out of pocket, and callbacks are often same-day

Lin Health applies the principles from PRT and neuroplastic pain research; it is not the clinic from the trials described above. For a sense of what recovery can look like, read Gina's story.

If your pain has persisted for months or years and treatments aimed at your body haven't brought lasting relief, a brain-first approach may be worth exploring.

FAQ

Is Somatic Experiencing the same as somatic tracking?

No. Somatic tracking is a technique within Pain Reprocessing Therapy: observing pain sensations through a lens of safety to teach the brain the signal isn't dangerous. Somatic Experiencing is a standalone trauma therapy that works with body sensations tied to traumatic memories. The names are similar, but the goals, methods, and evidence bases differ.

Does Somatic Experiencing work for chronic pain?

Direct evidence is limited. In two randomized trials of adults with low back pain and post-traumatic stress symptoms, SE improved trauma symptoms and fear of movement in one trial, but neither trial found greater pain or disability reduction than standard care. SE's stronger (though still preliminary) evidence is for PTSD-related symptoms.

What results has Pain Reprocessing Therapy shown?

In a randomized trial of 151 adults with chronic back pain, 66% of those receiving PRT were pain-free or nearly so after four weeks, versus 20% with placebo and 10% with usual care. At five years, 55% of the PRT group remained nearly or completely pain-free. Evidence outside back pain is still preliminary.

Can I do both Somatic Experiencing and PRT?

Yes, some people do. Trauma and chronic pain often co-occur, and the approaches target different problems, so they can complement each other. If you have significant PTSD symptoms, discuss sequencing with a licensed clinician, since untreated trauma can make pain-focused work harder.

Is PRT covered by insurance?

Individual PRT-trained therapists often bill out of pocket. Lin Health's coach-led program, which is based on PRT and related behavioral research, is covered by most major insurance plans in CO, TX, FL, CA, and NY, and most patients pay nothing out of pocket.

How do I know if my pain is the kind PRT was designed for?

PRT targets primary (neuroplastic) pain: pain that persists after healing or without a structural cause. Common signs include pain that doesn't match imaging, spreads or moves, and worsens with stress. A medical evaluation to rule out structural causes comes first.
