27 Pain Reprocessing Therapy Success Statistics

‍Clinical data on PRT trial outcomes, long-term durability, brain imaging findings, and how neuroplastic pain approaches compare to traditional chronic pain treatments

Chronic pain affects 24.3% of US adults, approximately 60 million people, yet the majority of treatments still target the body through medication, injections, or surgery. Pain Reprocessing Therapy (PRT) takes a fundamentally different approach. By retraining the brain's learned pain pathways rather than treating tissue damage, PRT has produced some of the strongest outcomes in chronic pain research. In the largest randomized controlled trial of PRT, 66% became pain-free or nearly pain-free after just 9 sessions. A 5-year follow-up confirmed those results held without additional treatment.

These 27 statistics capture the current evidence for PRT and the broader neuroplastic pain field, from clinical trial outcomes and brain imaging findings to the scale of chronic pain in America and the access barriers that still limit who can receive brain-based treatment.

Key Takeaways

• PRT produced high response rates in a rigorous trial - 66% of participants with chronic back pain became pain-free or nearly pain-free after 9 sessions
• Results hold long-term - 55% maintained relief at 5 years without any booster sessions
• PRT is expanding beyond back pain - early fibromyalgia pilots show growing effect sizes, reaching d=0.89 at 3 months
• Most chronic back pain may be neuroplastic - a primary care study found 88.3% were non-structural, pointing to the brain-based mechanisms PRT targets
• Access is severely limited - 169 million Americans live in mental health professional shortage areas, limiting access to PRT-trained providers

PRT Clinical Trial Outcomes: The Landmark Evidence

1. 66% of PRT participants with chronic back pain became pain-free or nearly pain-free

In the first randomized controlled trial of PRT, two-thirds became pain-free or nearly pain-free after treatment, compared to 20% in the placebo group and 10% receiving usual care. The trial enrolled 151 adults with chronic back pain averaging 10 years in duration. These response rates are among the highest reported in any chronic pain treatment trial for this population.

2. PRT effect sizes substantially exceeded typical chronic pain treatment benchmarks

The PRT trial produced effect sizes of Hedges' g = -1.14 compared to placebo and g = -1.74 compared to usual care for chronic back pain. Standard psychological therapies for chronic pain typically produce small-to-moderate effects (SMD -0.09 to -0.34 in Cochrane reviews). PRT's substantially larger effect sizes suggest it may work through different mechanisms than traditional coping-based approaches.

3. Nine treatment sessions over four weeks resolved pain that had lasted an average of 10 years

PRT delivered results in a compact treatment window: 9 sessions, 4 weeks. Participants had been living with chronic back pain for an average of 10 years, with a mean age of 41.1 and baseline pain intensity of 4.10 out of 10. The brevity of treatment relative to years of pain distinguishes PRT from ongoing management approaches that require indefinite continuation.

4. Shifting pain beliefs from body to brain mediated recovery

Before PRT, only 10% of participants attributed their pain to mind-brain processes. After treatment, 51% made brain attributions, and this cognitive shift was a key factor in pain reduction. The finding suggests that brain-driven chronic pain understanding is not just educational but therapeutic in itself.

5. Brain imaging confirmed reduced pain-related activation after PRT

Functional MRI scans showed that PRT reduced pain-related activation in the anterior midcingulate cortex, anterior prefrontal cortex, and anterior insula. The scans also revealed increased resting connectivity between prefrontal regions and the primary somatosensory cortex. These imaging findings provide evidence that PRT is associated with measurable changes in brain pain processing, not just changes in self-reported symptoms.

Long-Term Durability: Do PRT Results Last?

6. 55% of PRT patients remained pain-free or nearly pain-free at 5 years

A 5-year PRT follow-up found that 55% of PRT participants (21 of 38 followed) maintained pain-free or near-pain-free status. By comparison, 26% of placebo and 36% of usual care participants reached the same threshold at 5 years. These long-term results are notable because most chronic pain interventions show declining effects over time.

7. PRT required zero booster sessions for sustained 5-year relief

Participants in the PRT group received no additional sessions between the end of the original 4-week treatment and the 5-year follow-up. This durability without maintenance treatment contrasts with many chronic pain interventions that require ongoing sessions, medication refills, or repeat procedures. The finding aligns with PRT's theoretical model: once the brain stops generating unnecessary danger signals, the change can be self-sustaining.

PRT Beyond Back Pain: Expanding Applications

8. Brief PRT for fibromyalgia produced effect sizes that grew over time

A pilot study of 3 telehealth PRT sessions for fibromyalgia (N=35, 94.3% completion rate) found that pain intensity effect sizes increased from d=0.56 at 1 month to d=0.80 at 2 months to d=0.89 at 3 months. Pain interference showed a similar trajectory, reaching d=1.06 at 3 months. The growing effect sizes suggest PRT's benefits may compound after treatment ends as patients continue applying what they learned.

9. 42.3% of fibromyalgia patients reported clinically meaningful improvement after 3 PRT sessions

In the same pilot, 42.3% reported improvement on the Patient Global Impression of Change scale at 3 months, rating themselves as "much improved" or "very much improved." The study also found reductions in pain intensity, pain interference, and pain-related fear. While preliminary, these results support the hypothesis that PRT's mechanism may extend beyond chronic back pain.

10. PRT for chronic widespread pain achieved nearly 100% treatment adherence

A pilot randomized trial of PRT for widespread pain enrolled 32 patients (mean age 60, 90.6% female) in an 8-week protocol and reported near-perfect adherence. High adherence rates in chronic pain trials are uncommon, as many treatments carry side effects or require significant lifestyle changes. The result suggests that PRT's non-invasive, talk-based format may be more acceptable to patients than many alternatives.

Neuroplastic Pain: The Science Behind PRT

11. 88.3% of chronic back and neck pain in primary care was classified as neuroplastic

In a study of 222 patients at a community physiatry clinic, 88.3% was neuroplastic pain rather than pain caused by structural tissue damage. Only 5.0% had purely structural pain, with 6.8% showing mixed features. This finding challenges the widespread assumption that chronic pain always requires a structural fix and supports the rationale for neuroplastic pain approaches.

12. 97.7% of patients showed spinal imaging anomalies that did not explain their pain

From the same study, 97.7% had imaging anomalies, yet these findings did not correspond to the clinical diagnosis of structural pain in the vast majority of cases. This disconnect between imaging results and actual pain sources helps explain why many structural interventions fail to produce lasting relief. The data aligns with pain neuroscience research: imaging findings alone are poor predictors of who will have pain.

13. Between 5% and 15% of the general population has nociplastic pain

The International Association for the Study of Pain estimates that nociplastic pain affects 5-15% of the general population, with higher prevalence in females. Nociplastic pain occurs when the nervous system amplifies pain signals without clear tissue damage or nerve injury. This mechanism is central to PRT, which aims to retrain the brain's pain processing rather than treat a structural source, and it overlaps with what is commonly called central sensitization.

Chronic Pain in America: The Scale of the Problem

14. One in five people globally lives with chronic pain

A 2025 review in The Lancet confirmed that 1 in 5 globally lives with chronic pain, making it one of the most prevalent health conditions worldwide. The same review recognized psychological interventions with neurobiological frameworks as having scientific support for chronic pain self-management. The global scale of the problem underscores the need for treatments that can be delivered efficiently and without ongoing medication.

15. 24.3% of US adults had chronic pain in 2023, up from 20.4% in 2019

The most recent national data shows that 24.3% reported chronic pain, approximately 60 million adults, in the 2023 National Health Interview Survey. This represents a notable increase from 20.4% in 2019. The rising prevalence suggests that current treatment approaches are not adequately preventing acute pain from becoming chronic, which is the exact transition PRT is designed to address.

16. Chronic pain costs the US an estimated $560 to $635 billion annually

The total economic burden of chronic pain in the US exceeds heart disease individually, as well as cancer and diabetes individually, spanning direct healthcare spending, lost work productivity, and disability. Updated estimates from 2022 place the figure closer to $725 billion. These costs concentrate among patients cycling through medications, injections, imaging, and surgical consultations without lasting improvement.

17. 8.5% of US adults live with high-impact chronic pain

Beyond the broader prevalence figure, 8.5% have high-impact pain, roughly 22 million people who experience chronic pain that frequently limits life or work activities. This subpopulation carries the heaviest treatment burden and faces the highest risk of long-term disability. For patients whose pain persists despite standard medical care, brain-based treatments like PRT may offer a different path.

How PRT Compares to Other Behavioral Approaches

18. Emotional Awareness and Expression Therapy achieved 63.5% clinically significant pain reduction versus 17.1% for CBT

In a randomized trial of 126 older veterans with chronic musculoskeletal pain, 63.5% achieved significant reduction with EAET (30% or greater) compared to 17.1% for CBT. EAET, like PRT, targets the emotional and psychological drivers of chronic pain rather than teaching general coping skills. This head-to-head result suggests that therapies addressing the root neuroplastic mechanisms may outperform those focused on symptom management.

19. 35.7% of EAET patients achieved 50% or greater pain reduction versus 7.4% for CBT

At the higher threshold of 50% pain reduction, 35.7% achieved 50% reduction with EAET compared to 7.4% for CBT. At 6-month follow-up, 40.3% of EAET participants maintained clinically significant improvement versus 14.2% for CBT. The durability of EAET's trial results parallels what PRT's 5-year follow-up data shows for chronic back pain.

20. Standard psychological therapies for chronic pain produce small-to-moderate effects

The most recent Cochrane systematic review of psychological pain therapies found standardized mean differences ranging from -0.09 to -0.34 for outcomes including pain, disability, and mood. These effect sizes are considered small to moderate. PRT's substantially larger effect sizes (Hedges' g = -1.14 to -1.74) suggest it may represent a meaningful advance over the earlier generation of CBT-based pain treatments.

21. Acceptance and Commitment Therapy shows medium effects for pain interference with improvement over time

A 2024 meta-analysis of 21 ACT pain trials found medium effect sizes for pain interference, functional impairment, and depression, with small effects for pain intensity. At 3-month follow-up, ACT showed large effect sizes for functional impairment, suggesting benefits accumulate after treatment ends. ACT is one of the modalities used alongside PRT in comprehensive pain recovery programs.

Mental Health and Chronic Pain: The Connection PRT Addresses

22. 36.7% of adults with chronic pain meet criteria for major depressive disorder

A global study spanning 50 countries, 347K participants found that 36.7% of adults with chronic pain meet criteria for major depressive disorder and 16.7% for generalized anxiety disorder. The bidirectional relationship between pain and mental health means that treatments addressing only the physical dimension leave a significant part of the problem untreated. PRT and related approaches that engage emotional processing may address both simultaneously.

23. Brain-based pain therapy reduced depression, anxiety, and PTSD symptoms alongside pain

In the EAET versus CBT trial, EAET participants showed greater mental health improvements compared to CBT (PROMIS depression change: -5.12 vs -2.06; anxiety: -3.13 vs -0.64). These improvements occurred alongside, not instead of, pain reduction. The pattern suggests that therapies targeting chronic pain's emotional roots can produce broader health benefits beyond the pain itself.

The Opioid Crisis: Why Behavioral Alternatives Matter

24. Opioid prescriptions have decreased 52% since 2012, but 35.4 per 100 persons are still dispensed

National data shows that opioid prescriptions fell 52% from 260.5 million in 2012 to approximately 125.7 million in 2024. Despite this decline, 35.4 opioid prescriptions per 100 persons are still dispensed annually. The gap between reducing opioid prescribing and providing effective opioid therapy alternatives remains wide.

25. Behavioral therapy reduced pain severity and opioid use at 12 months

A 2025 trial found that both CBT and mindfulness reduced pain severity and opioid use in adults with opioid-treated chronic low back pain over 12 months. This adds to growing evidence that behavioral approaches can help patients reduce opioid reliance while managing pain effectively. For patients concerned about long-term opioid use, brain-based pain treatments offer a path that addresses pain at its neurological source.

Access and Cost: Barriers to Scaling PRT

26. Only 141 certified PRT practitioners exist worldwide

Despite evidence supporting its effectiveness for chronic back pain, only 141 PRT practitioners are certified worldwide, while an estimated 50 million Americans have chronic pain that may be suitable for neuroplastic treatment. This supply-demand gap means most patients cannot access PRT through an individually certified practitioner. Digital health platforms and coach-led PRT programs may help bridge this gap.

27. 169 million Americans live in mental health professional shortage areas

According to HRSA, 169 million face shortages in designated Mental Health Professional Shortage Areas, limiting access to the specialized providers who deliver therapies like PRT. This workforce gap is particularly acute for pain-focused psychological treatment, which requires training beyond general mental health practice. Insurance-covered programs that use trained recovery coaches may help expand access beyond the shortage.

How Lin Health Helps With Chronic Pain

Lin Health's approach is based on the same neuroscience that underlies PRT and related brain-based therapies. The program works by retraining brain pain pathways, addressing the fear, emotional patterns, and cognitive loops that keep chronic pain active after tissues have healed.

Each patient is paired with a trained recovery coach for weekly live sessions, supplemented by between-session chat support and an app with structured learning and practice materials. Modalities include CBT, ACT, Emotional Awareness and Expression Therapy, somatic tracking, and Pain Reprocessing Therapy principles, tailored to each patient's condition.

Lin Health is covered by most major insurance plans in Colorado, Texas, Florida, California, and New York, with coverage expanding to additional states. Most patients are fully covered with no out-of-pocket cost. Wait times are short, with same-day callbacks after signup to check eligibility.

For the clinical research behind this approach, see Lin Health's summaries of the PRT back pain trial, mind-brain reattribution research, and nociplastic pain research. Patient recovery stories are available at lin.health/stories.

If you have been living with chronic pain and have not found lasting relief through medication, physical therapy, or procedures, a brain-based approach may be worth exploring. Lin Health is covered by most major insurance plans, with most patients fully covered and a same-day callback to check eligibility. Check your eligibility.

Frequently Asked Questions

What is Pain Reprocessing Therapy?

Pain Reprocessing Therapy is a psychological treatment that helps people reinterpret chronic pain signals as non-dangerous. It works by retraining the brain's pain processing through somatic tracking, fear reduction, and cognitive reappraisal. PRT typically involves a limited number of sessions and does not use medication, surgery, or physical manipulation.

What is the success rate of Pain Reprocessing Therapy?

In the largest randomized trial, 66% of PRT participants with chronic back pain became pain-free or nearly pain-free after 9 sessions, compared to 20% with placebo. At 5-year follow-up, 55% maintained that result. Newer pilot studies in fibromyalgia show 42.3% reporting meaningful improvement after just 3 sessions.

Does PRT work for conditions other than back pain?

The strongest evidence is currently for chronic back pain from a published randomized trial. Preliminary pilot studies show promising results for fibromyalgia and chronic widespread pain, with effect sizes increasing over time. Research is ongoing, and the underlying theory suggests PRT may apply to conditions involving neuroplastic pain mechanisms.

How long does Pain Reprocessing Therapy take?

In the published clinical trial, PRT consisted of 9 sessions over 4 weeks. A fibromyalgia pilot used 3 telehealth sessions. Treatment length may vary by provider and condition, but the published protocols are significantly shorter than most ongoing pain management approaches.

Is PRT covered by insurance?

PRT sessions with individual practitioners may or may not be covered depending on provider credentialing and plan type. Programs that incorporate PRT principles alongside other evidence-based modalities, such as Lin Health, are covered by major insurance plans in several US states. Check with your insurance provider for specific coverage details.

What is the difference between PRT and CBT for pain?

PRT targets the brain's learned pain pathways and aims to reduce pain by reprocessing danger signals as safe. CBT for pain focuses on coping strategies, thought patterns, and behavioral changes to manage pain. Clinical data suggests PRT may produce larger effect sizes for chronic back pain, though CBT has a broader evidence base across more conditions.

Can PRT help reduce opioid use?

PRT has not been studied specifically for opioid reduction. However, related behavioral therapies (CBT and mindfulness) have been shown to reduce both pain severity and opioid use at 12 months. Because PRT targets the neurological source of chronic pain, it may reduce the perceived need for pain medication in patients whose pain is primarily neuroplastic.
