1. "My tests are normal — why does it hurt?"
About 25% of Koreans — 12.5 million people — have chronic pain (3+ months). Of these, 80% have normal MRI, CT, and blood tests. Even after analgesics, physical therapy, injections, and surgery, the pain persists. Common conclusions: "malingering", "psychological", "lifelong management". Neuroscience offers a different answer: real pain, but "brain, not body".
2. Neuroplastic pain
Pain is not a simple "sensor (body) → signal → brain" model. Pain experience is the result of the brain's "threat appraisal" of the signal. Lorimer Moseley's (University of South Australia) pain neuroscience:
- Acute injury (e.g., sprained ankle) → pain circuit activated
- The brain maintains "threat learning" even after healing
- In the same posture / movement / environment, "pain prediction" → real pain occurs
- This is the neuroplastic mechanism of chronic pain
Key: pain = brain's threat appraisal. Actual damage ≠ pain.
3. Boulder Back Pain Study — decisive evidence
Ashar et al. (2021) JAMA Psychiatry. Colorado Boulder + Harvard:
- Subjects: 151 chronic-low-back-pain patients (mean 11 years of pain)
- 3 arms: PRT (n=50), placebo injection (n=51), usual care (n=50)
- Intervention: PRT group, 4 weeks, 8 sessions
- Results (8-week follow-up):
- PRT: 66% pain-free or nearly pain-free
- Placebo: 20%
- Usual care: 10%
- fMRI: PRT group showed reduced activity in pain brain circuits (anterior cingulate, insula)
Effects maintained at 1-year follow-up.
4. PRT's 4 core principles
① Pain Reattribution
Consciously reattribute: "This pain is not body damage but brain threat learning". With each pain episode, self-state "this is safe pain". Only after medical clearance.
② Medical Reassurance
After thorough medical evaluation (MRI, CT, blood work, specialist) passes with "nothing wrong", use the result as "evidence". If the patient doubts the test results and seeks repeat tests, entering PRT is difficult.
③ Somatic Tracking
A variant of mindfulness. Observe pain with curiosity, neither avoiding nor fighting it. Describe location, intensity, texture; maintain a "not a threat" message. 5–15 minutes daily.
④ Emotion work
Much chronic pain is the somatization of anger, fear, sadness. Processing unresolved emotions (family conflict, workplace anger, trauma) directly reduces pain. Journaling, psychotherapy, expressive arts.
5. Common forms of neuroplastic pain
| Pain | Neuroplastic likelihood | Note |
|---|---|---|
| Nonspecific chronic low back pain | High (80%+) | MRI changes ≠ pain cause |
| Tension headache | Very high | 90% of daily headaches |
| Migraine | Medium | Partly neurological, partly neuroplastic |
| Fibromyalgia | Very high | Classic central sensitization |
| Irritable bowel (IBS) | High | Gut–brain axis learning |
| Chronic pelvic pain | High | Women, postpartum, post-trauma |
| TMJ / jaw joint | High | When dental exams are normal |
| Tinnitus | Medium | Partly auditory, partly neuroplastic |
6. When PRT should not apply
- Recent trauma / fracture
- Cancer (metastatic pain)
- Infection (bone, joint)
- Autoimmune (rheumatoid, ankylosing spondylitis)
- Cardiovascular (angina)
- Nerve damage (paralysis from disc compression)
These need medical treatment first. PRT applies to "medically unexplained pain".
7. Self-administered 8-week protocol
Week 1: Medical evaluation
- Comprehensive evaluation at orthopedics, neurology, pain medicine
- Rule out dangerous conditions with MRI / blood work
- Get a clear "nothing wrong" result
Week 2: Pain education
- Watch Lorimer Moseley "Pain Explained" videos
- Read Alan Gordon "The Way Out"
- Learn the pain = threat appraisal concept
Weeks 3–4: Pain reattribution
- State "this is safe pain" out loud to yourself with each episode
- Calm fear / anxiety with breathing
- Pain journal — "today's pain + situation + emotion"
Weeks 5–6: Somatic tracking
- Daily 10-min "pain observation" meditation
- Gradually reduce avoidance and immediate medication
- Gradually re-expose to previously avoided activities (walking, sitting)
Weeks 7–8: Emotion work
- Journaling and expression of unresolved emotions
- Conversations about family / relationship conflicts
- If needed, psychiatry / psychotherapy (emotion-focused)
8. Korean resources
- University-hospital pain clinics: comprehensive evaluation
- Korean Pain Society certified physicians
- PRT Korean materials: some psychiatry / psychologists are adopting
- Mindfulness meditation centers: somatic-tracking practice
- With severe depression or suicidal thoughts: 1577-0199
9. Relationship to medication and surgery
PRT does not replace drugs or surgery — they go together. As PRT works, drug use naturally falls and surgical needs decline. But never stop medication alone — always under a doctor's guidance.
