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

This systematic review looked at whether pain neuroscience education, an approach that teaches people how pain actually works in the body and brain, might help adults with osteoarthritis manage pain and related psychological factors like fear of movement or catastrophic thinking about pain. The researchers searched a wide range of databases and ended up with just four studies that fit their criteria, with interventions ranging from one to six sessions covering goal setting and ways of understanding pain differently. Across these studies, groups that received pain neuroscience education tended to show some improvement compared to other groups, but the effect sizes for things like pain catastrophizing and kinesiophobia (fear of movement) were small. The authors were cautious about crediting the education itself for these changes, noting that other factors, such as medications affecting acute pain after surgery, may have influenced the results in some studies. Overall the review points toward a modest, favorable trend for pain neuroscience education in osteoarthritis, but with only four studies and small effects, the authors themselves say more research is needed before drawing firmer conclusions.

If you live with osteoarthritis, you may have heard of approaches that focus on teaching people about how pain works, sometimes called pain neuroscience education. This review pulled together four studies that tested this kind of teaching, usually delivered over one to six sessions, alongside strategies for setting goals and understanding pain differently. The people who received this education did show some improvement compared to those who did not, but the size of that improvement was small when it came to things like feeling fearful of movement or feeling overwhelmed by pain thoughts.

The researchers also pointed out that other things happening in these studies, like pain medication used after surgery, could have played a role in the results, making it hard to say the education alone was responsible. Because only four studies were available and the effects were small, the evidence is still early stage. This does not mean the approach is ineffective, but it does mean there is not yet a large or well established body of evidence behind it for osteoarthritis specifically.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This review identified only four eligible studies examining pain neuroscience education for osteoarthritis, with intervention lengths ranging from one to six sessions and content focused on goal orientation and reframing understanding of pain. The pooled picture suggests a favorable trend for groups receiving this education, but the authors report small effect sizes for key psychosocial outcomes including pain catastrophizing and kinesiophobia. A notable limitation flagged by the authors is that some included studies involved acute postsurgical pain modulation, which may have been influenced by concurrent medication use, complicating attribution of any benefit to the educational component itself.

This makes it difficult to separate the specific contribution of pain neuroscience education from other co-occurring factors in the studied populations. Given the small number of included studies and the modest effect sizes, the current evidence base for pain neuroscience education in osteoarthritis appears limited in both quantity and certainty. The authors explicitly call for more studies to clarify the topic, indicating that conclusions at this stage should be treated as preliminary.
