Research

There is a growing body of peer-reviewed research supporting the idea that chronic primary pain can be maintained by central nervous system processes and that treatments targeting these processes can reduce pain and disability. While Pain Reprocessing Therapy (PRT) is relatively new, the broader fields of pain neuroscience education, cognitive behavioral approaches, and neuroplasticity-based interventions have substantial scientific support. Here are some of the most influential papers:

1. Pain Reprocessing Therapy (PRT)

Ashar, Y. K., et al. (2022).
JAMA Psychiatry, 79(1), 13–23.

Key findings:

  • 151 adults with chronic low back pain.
  • 66% of participants receiving PRT were pain-free or nearly pain-free after treatment.
  • Improvements were maintained at one-year follow-up.
  • Functional MRI demonstrated changes in brain regions involved in pain processing and threat perception.

2. Pain Neuroscience Education

Louw, A., et al. (2016).
Physiotherapy Theory and Practice, 32(5), 332–355.

Key findings:

  • Reduced pain catastrophizing.
  • Reduced fear of movement.
  • Improved function.
  • Most effective when combined with movement or rehabilitation.

3. Cognitive Functional Therapy

O’Sullivan, P., et al. (2018).
Physical Therapy.

This paper explains how changing beliefs, emotions, movement patterns, and nervous system sensitivity can substantially improve chronic pain.

4. Central Sensitization

Woolf, C. J. (2011).
Pain, 152(3 Suppl), S2–S15.

A landmark review describing how the central nervous system can amplify pain long after tissue healing has occurred.
