Movement-Based Interventions in Patients Affected by Bone Metastases: Impact on Physical Function and Functional Autonomy—A Systematic Review

<b>Background:</b> Bone metastases are a common complication in patients with advanced cancer. These patients often experience a decline in physical function and autonomy, particularly in the ability to perform Activities of Daily Living, and structured movement-based interventions may represent an important supportive strategy. The aim of this study is to describe the available evidence regarding the impact of physical activity and exercise interventions on functional status and ADL performance in patients with bone metastases. <b>Methods:</b> A systematic literature review was conducted in PubMed, Scopus, Embase, Web of Science, and CINAHL database up to March 2025 and reported according to PRISMA guidelines. Eligible studies included adults (≥18 years) with confirmed bone metastases who underwent physical activity interventions designed to enhance functional status and ADLs. Studies' methodological quality was assessed using the Joanna Briggs Institute critical appraisal tools, selected according to study design. <b>Results:</b> Eleven studies were included: four randomized controlled trials, four quasi-experimental studies, one randomized feasibility trial, one cross-sectional observational study, and one case report. Despite heterogeneity in intervention type, duration, and outcome measures, most studies reported improvements in physical function, including mobility, muscle strength, walking capacity, and endurance, as well as enhanced performance in ADLs and reductions in fatigue. No serious adverse events were reported. <b>Conclusions:</b> Structured physical activity appears safe and may improve function and independence in patients with bone metastases. These findings support the integration of individualized exercise programs into multidisciplinary supportive care.
