Bibliography & scientific documentation
Neuroplastic therapy is not an "alternative" theory; it is an approach that has been tested in randomized controlled trials (RCTs) and published in leading journals. Below we summarize the key findings, with an emphasis on the prospective and randomized studies, as well as the neuroscience behind the approach.
The landmark studies
The Boulder study — Pain Reprocessing TherapyAshar, 2022
In the best-known randomized trial, 151 adults with chronic back pain were divided into three groups: PRT, a placebo (sham injection) and usual care. After 4 weeks, 66% of the PRT group were pain-free or nearly pain-free, versus 20% for placebo and 10% for usual care — and a later follow-up confirmed that the benefit persisted for five years.[1][4] Functional MRI (fMRI) showed reduced activation of pain-related brain regions.[1] Film about this study: Pain Brain
EAET for fibromyalgiaLumley & Schubiner, 2017
A randomized trial of 230 patients with fibromyalgia compared EAET with Cognitive Behavioral Therapy (CBT) and with education. EAET was superior to education and, on several measures, to CBT as well — with significantly more patients achieving a >50% reduction in pain.[5]
EAET for chronic pain in veteransYarns, 2024
A randomized trial in 126 older veterans (many with PTSD) in JAMA Network Open: 63% of the EAET group achieved a pain reduction of ≥30%, versus only 17% of the CBT group.[2]
PSRT for back pain & for Long COVIDDonnino
Michael Donnino's group at Harvard tested the PSRT method in a pilot randomized trial for chronic back pain, with a significant reduction in bother and disability.[3] The same group applied it to patients with Long COVID, with an encouraging reduction in symptom burden.[6]
The neuroscience: what brain scans show us
How does an emotion, a trauma or a viral infection get "written" into the subconscious of the brain? Imaging studies (fMRI) provide concrete answers:
Pain "migrates" to the emotional circuits. In the classic study by Hashmi & Apkarian (2013), when back pain becomes chronic, its brain "address" moves from the regions of acute, bodily pain (insula, thalamus) toward the emotional circuits — the medial prefrontal cortex, the amygdala and the nucleus accumbens.[25]
Trauma and stress change the "danger threshold". The strength of the connection between the prefrontal cortex and the nucleus accumbens predicts which acute pain will become chronic.[25] Trauma, especially in childhood, up-regulates the "threat" circuits (amygdala) — which is why therapies that target the emotions (EAET, ISTDP) have physical effects.[17]
The brain "predicts" pain (predictive coding). Pain is not a simple "reading" of the sensory signals, but a prediction by the brain of how dangerous a situation is. When the brain "predicts" threat, it produces real pain even when the tissue is healthy.[1]
Viral infections as a "trigger". Infections such as SARS-CoV-2 can activate prolonged neuroinflammation and sensitization of the central nervous system; in a nervous system already "trained" for danger, this perpetuates symptoms even after the virus is gone.[6]
