Pain neuroscience education (PNE) aims to explain to patients the biological and physiological processes involved in a pain experience and, more importantly, defocus the issues associated with the anatomical structures. It has been demonstrated for musculoskeletal pain, PNE provides compelling evidence in reducing pain, disability, pain catastrophization, and limited physical movement. Rotator cuff tears (RCT) often lead to pain aggrevation, deterioration of patients' functioning and considerable economic burden for health care resources requiring consultations, physiotherapy, radiological examinations and surgery. Despite costly arthroscopic surgeries and long-term physiotherapy treatments, satisfactory results are scarce. The lack of satisfactory results at the end of all this effort suggests that some practices should be revised. Although PNE is likely to have beneficial effects on shoulder pathomechanics, to our knowledge, there is no randomized controlled research in the relevant literature investigating the effects of PNE in patients with an RCT. The present study aims to examine the effectiveness of PNE on clinical outcomes in a sample of patients with RCT.

Therapeutic interventions based on pain neuroscience education (PNE) have emerged as promising. It consists of educational sessions describing the neurobiology and neurophysiology of chronic pain and pain processing, with a particular focus on the role of the central nervous system on chronic pain and deemphasizing anatomical issues. PNE promotes the patients' understanding of chronic pain and changes maladaptive thoughts and cognitions (e.g. pain catastrophizing), which are important barriers to active therapy and exercise. Despite the apparent complexity of neuroscience education, patients are able to understand and remember it. Furthermore, there is evidence that an educational strategy addressing neurophysiology and neurobiology of pain can have a positive effect on pain, disability, catastrophizing, and physical performance, especially if combined with exercise.
