ObjectiveThis systematic review and meta-analysis aimed to determine the association between changes in patients' pain knowledge after pain science education (PSE) with treatment outcomes in people with chronic pain.MethodsSix electronic databases and 2 clinical trial registries were searched from inception to September 15, 2021 for studies where participants received PSE and had their pain knowledge and clinical outcomes assessed before and after PSE. Meta-analyses were performed for pain intensity, kinesiophobia, and pain catastrophizing. Physical function and quality of life outcomes were synthesized narratively. Risk of bias was assessed using the Cochrane tool for nonrandomized studies and the quality of evidence was assessed using GRADE.ResultsFourteen studies (n=1500 participants) were included. Meta-analyses revealed no significant associations between short-term (<12 wk) changes in pain neurophysiology knowledge with changes in pain intensity (n=1075, r=-0.01, 95% CI =-0.14 to 0.13, very low certainty), kinesiophobia (n=152, r=0.02, 95% CI =-0.27 to 0.24, very low certainty) and pain catastrophizing (n=976, r=-0.03, 95% CI=-0.18 to 0.11, low certainty). No significant associations were found between short-term changes in pain neurophysiology knowledge and physical function or quality of life either.DiscussionThese findings do not support a short-term association between improvements in pain neurophysiology knowledge and better treatment outcomes in people with chronic pain. Increased understanding of how PSE works, as well as better ways to measure it, may help clinicians deliver more targeted education to help patients reconceptualize pain and promote engagement in active treatment strategies (eg, exercise).Copyright © 2022 Wolters Kluwer Health, Inc.
