Rehabilitation Interventions for Adults With Complex Regional Pain Syndrome: A Scoping Review Protocol.

Objectives: This scoping review will explore the literature related to rehabilitation interventions for the treatment of adults living with complex regional pain syndrome (CRPS), describe the domains and outcome measures used to assess their effectiveness, and examine the neurophysiological bases of these interventions.

Introduction: The unremitting symptoms of CRPS, a chronic pain condition, are associated with long-term disability, poor psychological health, decreased emotional and social well-being, and reduced quality of life. Effective treatment for persistent symptoms is notoriously difficult. Therapeutic approaches such as graded motor imagery or pain exposure therapy are recommended for CRPS but show mixed results, insufficient effectiveness, variability in outcome measures, and unclear neurophysiological bases.

Inclusion criteria: This review will consider studies that include any form of non-invasive rehabilitation intervention delivered by a healthcare professional in any setting for adults with a CRPS diagnosis. Quantitative, qualitative and observational studies, text and opinion papers will be considered.

Methods: The Joanna Briggs Institute (JBI) methodology will be used to conduct this scoping review. MEDLINE, Embase, Scopus, APA PsycINFO, CINAHL, Cochrane, OpenGrey Google and ProQuest Dissertations and Theses Global (ProQuest) will be searched for studies in English published between 2007 and 2024. Two independent reviewers will screen the titles, abstracts, and full texts of the selected studies. Data collection will be performed using a tool developed by the researchers based on the standardised JBI tool. Data will be presented in a comprehensive narrative summary.
