Perceived factors influencing the success of pain neuroscience education in chronic musculoskeletal pain: a meta-synthesis of qualitative studies.

Purpose: We aimed to identify the factors influencing the success of Pain Neuroscience Education (PNE) in chronic musculoskeletal (MSK) pain from the perspective of those experiencing PNE first-hand.

Materials And Methods: We conducted a meta-synthesis of qualitative studies. Articles were found on MEDLINE Pubmed, EMBASE, Cochrane Library, CINHAL, and PsycINFO up to April 2023. Eligible qualitative studies focussed on adults (>16 years old) with a diagnosis of chronic primary or secondary MSK pain who performed PNE. Thematic synthesis by Thomas and Harden was followed. The Critical Appraisal Skills Programme (CASP) tool ensured the quality of the studies, while the Confidence in Evidence from the Reviews of Qualitative Research (CERQual) approach facilitated data confidence assessment.

Results: Nine studies were included (188 participants). Three analytical themes were developed: (i) "Efficient Communication of Information", emphasising the importance of accurate content transmission; (ii) "Emotional Support and Well-being", recognising emotional aspects as integral to treatment; and (iii) "Empowerment Promotion", focusing on information retention and personal transformation. The studies showed good quality, with moderate confidence in the evidence.

Conclusions: The perceived factors influencing the success of PNE are intricately related to the domain of communication, the emotional dimension of personal experience, and the capacity to be empowered.
