Neuroplastic pain, explained
The learned-pain mechanism PRT is designed to reverse — and how to recognize it.
Pain reprocessing therapy, explained.
Most chronic pain treatments try to mask pain or fix tissue. PRT does something different: it targets the learned brain process that keeps generating pain after the body has healed.
What is pain reprocessing therapy (PRT)?
Pain reprocessing therapy (PRT) is a psychological treatment that helps people reinterpret chronic pain as a false alarm rather than a sign of damage. By combining pain education, guided attention to sensations through a lens of safety, and graded return to feared movement, PRT aims to break the fear-pain cycle that sustains neuroplastic pain.
In the 2021 Boulder Back Pain study, 66% of participants with long-standing back pain were pain-free or nearly pain-free after four weeks of PRT — results largely maintained a year later.
At a glance
- What it is
- A structured psychological therapy for neuroplastic (nociplastic) pain
- Core idea
- Chronic pain is often a learned false alarm the brain can unlearn
- Key evidence
- Ashar et al., JAMA Psychiatry 2021 — 66% pain-free or nearly so vs 20% placebo, 10% usual care
- Typical course
- Weeks, not years — the trial protocol was 8 sessions over 4 weeks
- Best suited for
- Pain without ongoing tissue damage, after medical rule-out
- Related approaches
- VR embodiment training, graded exposure, CBT
Key takeaways
- PRT treats the pain system, not the tissue — which is why it can work when scans are normal and other treatments have failed.
- The central skill is somatic tracking: attending to pain sensations with curiosity and safety instead of fear.
- PRT requires a medical evaluation first — it's for pain that persists after serious causes are ruled out.
- Karuna's program applies the same reprocessing principles, adding VR embodiment and one-on-one coaching. See how it works.
What is pain reprocessing therapy?
PRT was developed by Alan Gordon and colleagues at the Pain Psychology Center, building on decades of pain-neuroscience research showing that chronic pain often persists because the brain has learned to produce it — a pattern called neuroplastic pain. If the brain learned to associate certain movements, positions, or situations with danger, it can also unlearn that association.
The therapy is short and structured. Rather than managing pain indefinitely, its explicit goal is to reduce or eliminate pain by changing how the brain interprets signals from the body.
PRT does not claim your pain is imaginary. It claims the opposite: pain is a real brain output, and because the brain constructs it, the brain can also stop constructing it once it's convinced the body is safe.
What are the core techniques of PRT?
- Evidence gathering — building a personal case that your pain is neuroplastic: normal tests, symptoms that move or vary with stress, pain that started in a stressful period, flares triggered by thoughts or weather rather than load.
- Somatic tracking — the signature technique. You attend to the pain sensation with light, curious attention while reminding yourself the sensation is safe. Watching pain through a lens of safety, rather than bracing against it, gradually retrains the alarm.
- Reappraisal of sensations — describing sensations neutrally (warm, tight, buzzing) instead of catastrophically (stabbing, damaging, crippling).
- Reducing fear and avoidance — gradually re-entering avoided movements and situations while feeling safe, so the brain collects proof that nothing bad happens.
- Cultivating positive affect — deliberately noticing ease, humor, and pleasant sensation; a threatened nervous system amplifies pain, a settled one turns it down.
Does PRT actually work? The Boulder study
The strongest evidence comes from a randomized controlled trial at the University of Colorado Boulder (Ashar et al., JAMA Psychiatry, 2021). 151 adults with chronic back pain — average duration about ten years — were randomized to PRT, an open-label placebo injection, or usual care.
| Group | Pain-free or nearly pain-free at 4 weeks |
|---|---|
| Pain reprocessing therapy | 66% |
| Placebo injection | 20% |
| Usual care | 10% |
Treatment effects were largely maintained at one-year follow-up, and functional MRI showed reduced activity in pain-related brain regions after treatment. For a psychological therapy in chronic pain — a field where 30% improvement is often considered success — these are unusually large effects.
Caveats worth knowing: participants had primary (neuroplastic) back pain, moderate average intensity, and were motivated volunteers. PRT hasn't been shown to treat pain from active tissue disease, and replication in other conditions is ongoing. That's why screening — confirming your pain fits the neuroplastic profile — matters so much.
Who is PRT right for — and who isn't it for?
PRT is designed for pain that is primarily neuroplastic: chronic pain that persists despite normal or reassuring medical workup. That describes a large share of chronic back pain, neck and shoulder pain, fibromyalgia, tension headaches, and pain that has outlived its original injury.
It is not a substitute for medical care when pain has an ongoing structural or systemic driver — active inflammation, infection, tumor, fracture, or true progressive nerve compression. And it can complement, not replace, treatment for neuropathic pain, where a centralized component often rides on top of real nerve injury.
If you're unsure which side you're on, take the neuroplastic pain quiz to see how many neuroplastic features your pain shows, then start with our chronic pain guide and get a physician's evaluation — that's also the first step of Karuna's program.
How is PRT different from CBT?
| CBT for chronic pain | Pain reprocessing therapy | |
|---|---|---|
| Goal | Cope better with pain; improve function | Reduce or eliminate the pain itself |
| View of pain | A condition to manage | A reversible false alarm |
| Core method | Challenge unhelpful thoughts, pace activity | Retrain interpretation of the sensation itself (somatic tracking) |
| Typical stance toward sensation | Distract from or accept it | Attend to it — through a lens of safety |
Both are evidence-based, and they're not enemies — many clinicians blend them. But the stance is different: CBT helps you live alongside pain; PRT tries to talk the alarm system out of producing it. For a wider view of the options, see chronic pain treatment.
How does Karuna use pain-reprocessing principles?
Karuna Virtual Embodiment Training (KVET)™ is built on the same science: pain is a protective output the brain can recalibrate. The program pairs the cognitive side of reprocessing — education, safety reappraisal, graded exposure — with something PRT alone doesn't have: embodied visual feedback in VR, which lets the brain re-experience the painful body region moving comfortably.
A dedicated pain coach guides the weekly work and a physician oversees care throughout. The program runs 12 weeks, entirely from home, and is drug-free. Read how it works or talk with the care team about whether your pain fits.
Frequently asked questions
Is pain reprocessing therapy legitimate?
Yes. PRT was tested in a randomized controlled trial published in JAMA Psychiatry (2021) with results among the strongest ever reported for chronic back pain, including brain-imaging changes and one-year durability. It's grounded in mainstream pain neuroscience — the same body of work behind the ICD-11's recognition of nociplastic pain.
Does PRT mean my pain is psychological?
No. PRT treats pain as a real, physical brain process — a protective alarm that has become oversensitive. Emotions and stress influence the alarm's sensitivity, but the pain itself is never imaginary, and needing PRT says nothing about your mental strength.
How long does PRT take to work?
The Boulder trial delivered eight sessions over four weeks, and most responders improved within that window. Real-world courses vary — some people shift quickly once the fear breaks, others need a few months of practice, especially with long-standing pain or high baseline fear.
Can I do PRT on my own?
The concepts are learnable from books and courses, and self-guided somatic tracking helps some people. But most benefit from structured guidance — fear is hard to unwind alone, and a trained guide catches the subtle bracing and checking behaviors that keep the alarm alive. Structured programs like Karuna's exist for exactly that reason.
Does PRT work for conditions other than back pain?
The landmark trial was in chronic back pain, but the mechanism it targets — neuroplastic pain — shows up across many conditions, including fibromyalgia, neck pain, and tension headaches. Clinical use in these conditions is promising and growing, though condition-specific trials are still catching up.
What if PRT doesn't work for me?
A partial or slow response doesn't mean you're broken — it usually means fear pathways need more repetition, or that your pain has a mixed mechanism needing combined care. Options include adding VR-based retraining, graded physical therapy, or reviewing the diagnosis with your physician. See the full treatment landscape.
