Upper-limb rehabilitation interventions delivered by healthcare professionals for adult patients in the intensive care unit setting: protocol for a scoping review.

INTRODUCTION: Post-intensive care syndrome affects up to 70% of adult intensive care unit (ICU) survivors, with ICU-acquired weakness contributing substantially to long-term disability. Despite evidence supporting early and structured rehabilitation to enhance physical recovery, targeted upper-limb rehabilitation approaches in the ICU remain comparatively underexplored. This scoping review will map and summarise existing evidence on upper-limb weakness and rehabilitation strategies delivered by healthcare professionals for critically ill adults. METHODS AND ANALYSIS: This scoping review protocol has been developed in accordance with the Joanna Briggs Institute methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews, ensuring transparent and comprehensive reporting. Searches will be conducted in MEDLINE (Ovid), CINAHL (EBSCO), Embase, Scopus and the Cochrane Central Register of Controlled Trials (CENTRAL). The search will include studies published between March 2009 and August 2025, aligning with National Institute of Clinical Excellence (NICE) Guideline CG83 (2009), which marked a major policy shift in ICU rehabilitation practice. Quantitative data will be summarised descriptively (eg, frequencies and proportions), while qualitative data will undergo thematic synthesis to identify patterns in experiences, perceptions and implementation of upper-limb rehabilitation. Grey literature (eg, OpenGrey and relevant conference proceedings) will also be screened to reduce publication bias. Rayyan AI software will be used to manage citation screening and reviewer collaboration; no artificial intelligence-assisted decision tools will be used to determine study inclusion. ETHICS AND DISSEMINATION: As this review will synthesise previously published data, ethical approval is not required. Results will be disseminated through peer-reviewed publication, conference presentations and open-access platforms. Findings from this review will inform the development of evidence-based ICU rehabilitation guidelines and highlight priorities for future research to improve upper-limb recovery in critically ill adults. STUDY REGISTRATION: Open Science Framework (osf.io/j86nf).
