Pain Reprocessing Therapy (PRT) is a psychological treatment designed to help the brain “unlearn” chronic pain that persists without an underlying injury or structural cause. Rather than managing or coping with pain, PRT aims to eliminate it by teaching the brain that the pain signals it’s producing are a false alarm. In a landmark 2021 study, 66% of chronic back pain patients who completed a four-week PRT program were pain-free or nearly pain-free afterward, compared to just 10% of those who received no treatment.
How Chronic Pain Becomes a Brain Problem
Traditional pain works like a direct alarm system: you stub your toe, nerves send a signal to the brain, and you feel pain proportional to the injury. Once the tissue heals, the signal stops. But in many cases of chronic pain, the original injury has long since healed, or no injury existed in the first place. The brain continues generating pain on its own.
This type of pain, sometimes called neuroplastic or nociplastic pain, arises from changes in how the brain processes sensory information. Brain imaging studies show that people with chronic pain develop increased activity in pain-processing areas, recruit brain regions that don’t normally respond to pain signals, and experience disruptions in the neural pathways that are supposed to dial pain down. Over time, the brain essentially gets stuck in a pain loop, interpreting normal body sensations as dangerous.
The result is real pain with no ongoing tissue damage. It’s not imagined or exaggerated. The nervous system is genuinely producing pain signals, but those signals no longer reflect what’s happening in the body. PRT targets this specific type of pain.
The Core Idea Behind PRT
PRT is built on a straightforward premise: if the brain learned to produce pain in the absence of injury, it can also learn to stop. The treatment works by helping people reinterpret their pain signals as non-threatening, which over time reduces and can eliminate the pain itself. This is fundamentally different from most chronic pain treatments, which focus on managing symptoms, building tolerance, or accepting pain as a long-term reality.
Cognitive Behavioral Therapy (CBT) for pain, for instance, typically helps people change their thoughts and behaviors around pain to function better despite it. Acceptance and Commitment Therapy (ACT) encourages people to accept pain while pursuing meaningful activities. PRT goes a step further: it treats the pain itself as the target, aiming to convince the brain that the danger signal is inaccurate so the pain resolves.
What Happens in a PRT Session
PRT uses several techniques, but the central one is called somatic tracking. It combines three elements: mindful attention to pain sensations, safety reappraisal (reminding yourself the pain isn’t dangerous), and cultivating a sense of calm or positive emotion while observing the sensation.
In practice, somatic tracking looks like this:
- Observe the sensation without reacting. You bring your attention to the pain and notice it with curiosity rather than fear. Is it sharp or dull? Pinpointed or widespread? Moving or staying in one place? The goal isn’t to fix anything. You’re simply watching, the way you might observe a passing cloud.
- Add a message of safety. You remind yourself that the pain is a protective response, not evidence of damage. This might sound like “this is uncomfortable, but not harmful” or “my body is safe.” The key is finding a statement that feels genuinely believable to you, not just a mantra you repeat mechanically.
- Shift toward a positive emotional state. You do whatever helps you feel lighter, whether that’s recalling a good memory, softening your breathing, or simply easing the intensity of your focus. The point is to observe the sensation with ease rather than tension.
Therapists also help patients build what’s called an “evidence list,” a running collection of observations about how their pain behaves in ways that structural pain wouldn’t. For example, if your back pain disappears on vacation but returns at work, or if it moves from one side to the other, or if it flares when you’re stressed but not during physical activity, those are clues that the brain is driving the pain rather than a damaged structure. Recognizing these patterns helps weaken the brain’s conviction that the body is in danger.
PRT also includes work on managing emotions that amplify pain. Fear, anger, and stress all activate the same threat-detection systems in the brain that produce pain signals. Learning to process these emotions can reduce the fuel that keeps the pain cycle running.
The Research Behind PRT
The strongest evidence for PRT comes from a randomized controlled trial conducted at the University of Colorado Boulder, published in JAMA Psychiatry in 2021. Researchers recruited 151 people with chronic back pain lasting at least six months and randomly assigned them to one of three groups: PRT treatment, a placebo injection, or no treatment at all.
The PRT group received eight one-hour sessions over four weeks. After treatment, 66% of those patients were pain-free or nearly pain-free. In the placebo group, 20% improved to that level, and in the no-treatment group, just 10% did. Brain imaging before and after the study showed that PRT reduced activity in pain-processing regions, suggesting the treatment was changing how the brain responded to signals from the body.
These results are striking for a condition that often resists treatment for years. However, this remains a single study with a relatively small sample, and participants were screened to confirm their pain was likely neuroplastic rather than structural. How well PRT works for broader chronic pain populations is still being explored.
Who PRT Is Designed For
PRT is specifically intended for people whose chronic pain doesn’t have an active structural cause. That distinction matters. In the Boulder study, participants underwent brain imaging and clinical evaluation to rule out specific medical conditions before starting treatment. People with sciatica (nerve-related leg pain indicating a clear structural problem) were excluded entirely.
Several patterns suggest pain may be neuroplastic rather than structural:
- Pain that spreads to multiple body regions over time
- Pain triggered by stress or emotional situations rather than physical activity
- Pain that fluctuates based on attention, meaning it gets worse when you focus on it or when someone asks about it
- Pain that persists long after an injury should have healed, with imaging showing no ongoing damage
- Pain that moves around or behaves inconsistently, appearing in different locations or changing in character
If your pain has a clear structural origin, like a fracture, active inflammation, infection, or progressive disease, PRT is not a substitute for medical treatment. The therapy works by convincing the brain that pain signals are inaccurate, which is only appropriate when they actually are. A thorough medical evaluation to rule out structural causes is an important first step before pursuing PRT.
How PRT Differs From “It’s All in Your Head”
One of the biggest barriers to neuroplastic pain treatment is the fear of being dismissed. Many people with chronic pain have been told their symptoms aren’t real, or that the problem is purely psychological. PRT takes a different position: the pain is completely real. It’s generated by the brain, but all pain is generated by the brain. The difference is that neuroplastic pain reflects a malfunction in the brain’s threat-detection system rather than ongoing tissue damage.
This reframing is central to how PRT works. Knowing that pain can exist without injury, and that the brain can learn to stop producing it, gives people a concrete mechanism to work with. It’s not about willpower or positive thinking. It’s about retraining a neural process that has gone wrong, using specific techniques that target how the brain evaluates danger signals from the body.
What to Expect From Treatment
A typical course of PRT involves around eight sessions with a trained therapist, usually spread over four to eight weeks. Sessions focus on education about how neuroplastic pain works, guided somatic tracking exercises, emotional processing, and gradually reintroducing movements or activities that have become associated with pain. Therapists help patients practice painful movements while reappraising the sensations they experience, building evidence that the movement is safe.
Progress isn’t always linear. Some people notice shifts within the first few sessions, while others take longer to see changes. The somatic tracking technique is also something you practice on your own between sessions, building the skill of observing pain without fear until the brain’s threat response naturally quiets down. Over time, sensations that once triggered a full pain response start to feel less intense, less threatening, and eventually may stop registering as pain at all.
