A base review found that IMPT participation leads to sustained improvements in wellbeing, but substantial heterogeneity in program dose and content limited conclusions about optimal design. This first update as a living systematic review (LSR) aimed to assess the long\u2010term effects (\u2265\u200912\u2009months post\u2010treatment) of IMPT for chronic primary musculoskeletal pain and explore patterns in treatment effectiveness to inform program optimization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Databases and Data Treatment<\/jats:title>\n                    <jats:p>This LSR updated the base review's systematic search (January 2025) in Medline, Embase, PsycInfo and Cinahl. Eligible studies included adults with chronic primary musculoskeletal pain who completed IMPT and were followed for at least 12\u2009months. Two reviewers independently screened studies, extracted data and assessed risk of bias. Standardised mean changes were calculated for nine outcome domains plus health\u2010related quality of life (HRQoL).

HRQoL improvement underscores the long\u2010term effectiveness of IMPT in improving overall well\u2010being. Highly tailored, individually delivered IMPT programs that integrate recent innovations and are under 30\u2009h in duration appear most effective in reducing pain\u2010related disability and improving health\u2010related quality of life.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ejp.70174","type":"journal-article","created":{"date-parts":[[2025,11,28]],"date-time":"2025-11-28T11:50:25Z","timestamp":1764330625000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Longitudinal Outcome Evaluations of Interdisciplinary Multimodal Pain Treatment Programs for Patients With Chronic Primary Musculoskeletal Pain: A Living Systematic Review"],"prefix":"10.1002","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7497-0304","authenticated-orcid":false,"given":"Elise","family":"Cnockaert","sequence":"first","affiliation":[{"name":"Spine, Head and Pain Research Unit Ghent, Department of Rehabilitation Sciences, Faculty of Medicine and Health Sciences Ghent University  Ghent Belgium"},{"name":"Pain in Motion International Research Group, www.paininmotion.be  Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirsty","family":"Musch","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Research School CAPHRI Maastricht University  Maastricht the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8928-4307","authenticated-orcid":false,"given":"Stefan","family":"Elbers","sequence":"additional","affiliation":[{"name":"Research Group Innovation of Movement Care, Research Centre Healthy and Sustainable Living University of Applied Sciences Utrecht  Utrecht the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4546-4576","authenticated-orcid":false,"given":"Alb\u00e8re","family":"K\u00f6ke","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Research School CAPHRI Maastricht University  Maastricht the Netherlands"},{"name":"Adelante Centre of Expertise in Rehabilitation and Audiology  Hoensbroek the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8946-4383","authenticated-orcid":false,"given":"Jessica","family":"Van Oosterwijck","sequence":"additional","affiliation":[{"name":"Spine, Head and Pain Research Unit Ghent, Department of Rehabilitation Sciences, Faculty of Medicine and Health Sciences Ghent University  Ghent Belgium"},{"name":"Pain in Motion International Research Group, www.paininmotion.be  Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5134-4087","authenticated-orcid":false,"given":"Ivan","family":"Huijnen","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Research School CAPHRI Maastricht University  Maastricht the Netherlands"},{"name":"Adelante Centre of Expertise in Rehabilitation and Audiology  Hoensbroek the Netherlands"},{"name":"Zuyd University of Applied Sciences  Heerlen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9503-366X","authenticated-orcid":false,"given":"Rob","family":"Smeets","sequence":"additional","affiliation":[{"name":"Pain in Motion International Research Group, www.paininmotion.be  Belgium"},{"name":"Department of Rehabilitation Medicine, Research School CAPHRI Maastricht University  Maastricht the Netherlands"},{"name":"CIR Expertise Centrum Chronische Pijn  Eindhoven the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,28]]},"reference":[{"key":"e_1_2_10_2_1","volume-title":"Empirical Assessment of Within\u2010Arm Correlation Imputation in Trials of Continuous Outcomes","author":"Balk E.
