Pain Reprocessing Therapy: The Science and How to Start

What Is Pain Reprocessing Therapy?

Pain Reprocessing Therapy is a psychological treatment that retrains the brain to stop producing chronic pain. That's it. That's the whole thing.

It works for a specific pattern. If your pain gets worse on stressful days and better on vacation. If your MRI came back normal and you still hurt. If your pain moves around. If it flares before big meetings or Monday mornings or difficult phone calls. If it started during a hard period in your life, or after an injury that healed a long time ago and the pain stayed.

You're describing the exact pattern PRT was designed for. Two-thirds of people with that pattern became pain-free in the Boulder study (Ashar et al., JAMA Psychiatry, 2022). Four weeks. No medication. No surgery. No devices.

Where PRT Came From

Alan Gordon didn't discover PRT in a research lab. He discovered it trying to fix his own body.

In his twenties, he had 22 chronic symptoms. Back pain. Neck pain. Jaw pain. Wrist pain. Stomach problems. He'd been through the full medical maze. MRIs, specialists, physical therapy, nothing worked. Some doctors hinted it was psychological, which landed as an insult on top of the pain.

A friend gave him Dr. John Sarno's book Healing Back Pain. Sarno was an NYU physiatrist who had spent thirty years arguing that most chronic pain was driven by the nervous system, not structural damage. Gordon didn't love the book. The framing felt dated. The evidence was clinical experience, not trials. But something clicked. His pain was worse on stressful days. Better on vacation. It moved in ways no anatomy textbook could explain.

He started experimenting on himself. Over months, all 22 symptoms faded. Then they were gone.

He opened the Pain Psychology Center in Los Angeles. He refined Sarno's original insight into a structured protocol you could teach in nine sessions. In 2022, researchers at the University of Colorado Boulder tested it in a randomized trial and published the results in JAMA Psychiatry.

Gordon had 22 symptoms and no answers. Sound familiar?

How Pain Reprocessing Therapy Works

Here's the core idea. Pain equals sensation plus fear. If you can reduce the fear, you reduce the pain. Not the sensation of it. The pain itself.

Think of a car alarm going off in a parking lot. Nobody runs. Nobody calls 911. Because everyone knows it's a false alarm. Your chronic pain works the same way. The pain is real. The sensation is real. Central sensitization is real. But for most people with chronic pain, the brain is running a threat program with no threat behind it. PRT teaches your brain to hear the alarm and recognize it as false. Once that happens, the alarm gets quieter. Sometimes it stops entirely.

The Boulder protocol has five components. Each one is also something you can practice on your own, or with tools that make it easier.

Education first. You learn what brain-generated pain actually is and why it persists past the point where tissue healing should have ended it. A 2016 meta-analysis by Adriaan Louw and colleagues found that pain neuroscience education by itself reduces pain, fear, and disability. Understanding is the first intervention. PainApp's condition-specific courses teach this the way Louw's research says it should be taught. Short lessons. Concrete examples. Daily.

Then the evidence sheet. In the Boulder study, patients wrote down every indicator their pain was probably neuroplastic. The days it vanished. The stressors that lit it up. The MRI finding that didn't match where the pain lived. The time they forgot about it during a good conversation. This list becomes the reference they return to when their brain tries to convince them the pain is about their body. PainApp's F.I.T. Pain Tracker builds this automatically. You check in daily. It watches for the Frequency, Intensity, and Triggers patterns. Over a few weeks, your evidence sheet assembles itself from your own data.

Then somatic tracking, the heart of the protocol. You attend to pain sensations with curiosity instead of fear, while reminding your nervous system you're safe. Alan Gordon describes it as watching the pain the way a snorkeler watches a fish. Curious. Unafraid. Studying it without trying to fix it. PainApp's guided somatic tracking sessions walk you through this daily. Beginner sessions to start. Harder ones as you build the skill. You press play, you follow the voice, you practice.

Then targeting fear responses. When the pain spikes and your stomach tightens, that tightness IS the fear half of the equation. You learn to recognize the reaction and gently interrupt it. PainApp's AI Pain Coach is trained on the same conversational moves PRT therapists use. You tell it what happened. It helps you reframe. Over time, those interruptions get shorter and the spike gets smaller.

Finally, positive affect induction. Humor, savoring, gratitude. Not as a feel-good add-on. Because positive emotional states are physically incompatible with the threat state your nervous system is stuck in. The Boulder researchers had patients actively cultivate moments of safety. PainApp builds this into the daily practice structure. Short enough you can do it on a bad day. Consistent enough to shift your baseline over weeks.

These aren't five different apps. They're the same app, built to deliver the five parts of the Boulder protocol from your phone.

The Boulder Study and What It Proved

Now the data. The reason any of this is worth trying.

In 2022, a team at the University of Colorado Boulder published a randomized controlled trial in JAMA Psychiatry (Ashar et al., 2022) that tested Pain Reprocessing Therapy against placebo and usual care in 151 adults with chronic back pain. Participants had averaged ten years of pain. A decade. Not mild back pain. Not recent back pain. Lives that had been reshaped by it. After nine sessions of PRT over four weeks, 66% were pain-free or nearly pain-free, compared to 20% with placebo and 10% with usual care. Lead researcher Yoni Ashar called the effect sizes 'very rarely observed in chronic pain treatment trials.' Most pain treatments produce effects in the 0.2 to 0.4 range. PRT produced effects five to eight times larger. A five-year follow-up (Ashar et al., JAMA Psychiatry, 2025) found most PRT patients remained pain-free or nearly pain-free with no booster sessions.

Read that again if you need to. Ten years of pain. Four weeks of treatment. Pain-free at five years.

The researchers scanned participants' brains before and after. This is the part that kills the 'it's all in your head' objection. fMRI data showed PRT reduced pain-related activation in the anterior midcingulate cortex, anterior prefrontal cortex, and anterior insula. It also strengthened connectivity between the brain's thinking regions and its pain-processing regions. The brain physically reorganized. You could see it on a scan.

Then the mediation analysis published in JAMA Network Open (Ashar et al., 2023). This one answered the most important question: what actually caused the pain to drop? The answer: shifting from 'my pain is tissue damage' to 'my pain is brain-generated.' Before PRT, only 10% of patients attributed their pain to mind-brain processes. After PRT, 51% did. And the patients who shifted the most got the biggest pain reductions. Understanding was the mechanism. Which means the education piece isn't just background. It's the treatment.

Panzel, Buchel, and Ashar (Annals of Neurology, 2025) then showed that chronic pain patients are cranked up in sensitivity across every sense, not just pain. Sound. Light. Touch. The brain's volume knob is stuck high across the whole system. PRT turned it down across the whole system.

The Honest Limitations

This is one study, for one condition, by the team that developed PRT. More trials are underway. Independent replications are coming. The results were strong enough for JAMA Psychiatry. The five-year follow-up held. The brain imaging confirmed distinct mechanisms beyond placebo. A separate study of the same placebo injection produced effects comparable to over-the-counter ibuprofen, and PRT did something substantially beyond that. The evidence will get stronger as other labs replicate. Right now, it's the strongest clinical evidence in the field of chronic pain.

The Access Crisis: Why You Probably Can't Get PRT

Here's the problem.

There are 141 certified PRT practitioners in the world. Worldwide. For more than 50 million Americans with chronic pain that probably has a neuroplastic component. Sessions at the Pain Psychology Center run $150 to $350 each. The nine-session protocol runs $1,500 to $2,800 out of pocket. Insurance rarely covers it because the diagnostic codes for nociplastic pain are new and unfamiliar to most claims systems. On top of that, 169 million Americans live in federally designated Mental Health Professional Shortage Areas, where even regular therapists are hard to find.

So if you read the Boulder study and want to try PRT, you probably can't. Not in person. Not with a trained therapist. Not at any price most people can afford. This is one of the reasons the stress-pain connection keeps getting missed by the medical system. The people who understand it aren't the ones most patients can reach.

That's why PainApp exists. Not as a replacement for in-person PRT with a skilled clinician. As the only way most people will ever access brain-based pain recovery. Guided somatic tracking. An AI coach trained on PRT principles. A pain tracker that builds your evidence sheet automatically. $29.99 a quarter, or less than the cost of one in-person PRT session for an entire year.

Your Brain Learned This Pain

Your brain learned this pain. It can unlearn it. The strongest evidence in chronic pain research says so. The brain scans confirm it. The five-year data backs it up. The mechanism travels beyond chronic back pain to fibromyalgia, chronic migraine, and most neuroplastic pain conditions where central sensitization is the driver.

The question isn't whether PRT works. It's whether it works for YOUR specific pain. The free assessment looks at your patterns and tells you what the research says about them. Three minutes. No account needed. Built on the same screening criteria the Boulder trial used to identify candidates for treatment.
