In a 2017 NIH-funded randomized controlled trial, EAET was found to be more than x2 as effective at providing a 50% or more pain reduction than CBT (Cognitive Behavioral Therapy) among fibromyalgia patients.
In a 2020 clinical trial, EAET was more effective at achieving pain reduction than CBT (Cognitive Behavioral Therapy) among military veterans with chronic musculoskeletal pain.

In 2019, EAET was recommended by the US Department of Health and Human Services to combat the opioid epidemic; it was considered a Pain Management Best Practice.
The brains of chronic pain sufferers differ from those of healthy people (specifically in the default mode network), and neuroimaging allows researchers to "see" pain.
In a randomized controlled study from the University of Colorado-Boulder, Pain Reprocessing Therapy (PRT) is explored as a treatment for chronic back pain among 100 subjects. 66% of subjects in the PRT group reported being pain-free or nearly pain-free by the end of the 4-week trial. Objective data in the form of functional MRI imaging pre- and post-treatment revealed that PRT changed the subjects' brains default mode network.
