Person-centred management of upper limb complex regional pain syndrome: an integrative review of non-pharmacological treatment.

Introduction: Complex Regional Pain Syndrome (CRPS) is most common in the upper limb and associated with high disability. The purpose of this review was to critically appraise and synthesise literature exploring non-pharmacological treatment for upper limb CRPS, to guide upper-limb-specific management.

Methods: Using an integrative review methodology, 13 databases were searched to identify all published studies on non-pharmacological management of upper limb CRPS. The Crowe Critical Appraisal Tool was used to provide quality ratings for included studies, and analysis employed a qualitative descriptive approach.

Results: From 236 abstracts reviewed, 113 full texts were read, and 38 articles selected for data extraction. Designs included single case ( = 14), randomised controlled trial ( = 8), prospective cohort ( = 8), case series ( = 4), retrospective ( = 3), and mixed methods ( = 1). Interventions were categorised as sensory retraining ( = 13), kinesiotherapy ( = 7), manual therapies ( = 7), physical modalities ( = 6), and interdisciplinary treatment programmes ( = 5). All studies measured pain intensity, and most ( = 24) measured physical parameters such as strength, movement, or perceptual abilities. Few measured patient-rated function ( = 13) or psychological factors ( = 4). Quality ratings ranged from 30% to 93%, with a median of 60%.

Conclusion: Methodological quality of non-pharmacological treatment approaches for upper limb CRPS is overall poor. Movement, desensitisation, and graded functional activity remain the mainstays of intervention. However, despite the impact of CRPS on wellbeing and function, psychological factors and functional outcomes are infrequently addressed. Further robust research is required to determine which aspects of treatment have the greatest influence on which symptoms, and when and how these should be introduced and progressed.
