Effectiveness of Interventions Based on Pain Neuroscience Education on Pain and Psychosocial Variables for Osteoarthritis: A Systematic Review.

UNLABELLED: Osteoarthritis (OA) is the most common joint condition. It affects more than 300 million people worldwide, who suffer from pain and physical disability.

OBJECTIVE

To determine the results of cognitive educational interventions for pain management and psychosocial variables in adults with OA.

METHOD: A systematic review was conducted based on searches in MEDLINE, OVID, LILACS, Scopus, PEDro, OTseeker, The Cochrane Library, EBSCO, and Google Scholar. The search strategy included the main terms neuroscience education and osteoarthritis, without any re-strictions with regard to dates or study type (PROSPERO register CRD42021222763).

RESULTS

We included four articles that implemented the intervention in 1-6 sessions, addressing concepts related to goal orientation and providing strategies for understanding pain. The results suggest that there is an improvement between the groups (PNE) when compared, but this cannot necessarily be attributed to pain neuroscience education (PNE), as small effect sizes for variables such as pain catastrophizing and kinesiophobia were observed. The response in the modulation of acute pain following the surgical procedure may produce a variation in the responses and this may be mediated by medications.

CONCLUSION

The study revealed an improvement in favor of the groups managed with PNE, although more studies documenting the topic are warranted.
