OBJECTIVE: The primary aim of this study was to evaluate the safety and efficacy of early mobilization in patients with aneurysmal subarachnoid haemorrhage. DESIGN: Systematic review with meta-analysis of randomized controlled studies and observational studies. PATIENTS: Patients with aneurysmal subarachnoid haemorrhage. METHODS: PubMed, Embase, CINAHL, Web of Science, Pedro, and the Cochrane Library databases were searched. A systematic review and meta-analysis were performed. Screening and data extraction were performed by 2 independent reviewers. RESULTS: Sixteen studies involving 1,757 patients were included. Meta-analysis of the data estimated that early mobilization improved mRS score at discharge (mean difference -1.39, 95% CI -2.51 to -0.28, L2 86%) and at 3 months (mean difference -1.10, 95% CI -1.54 to -0.66, L2 7%). Early mobilization was associated with a reduction in cerebral vasospasm rate, both radiological (OR 0.66, 95% CI 0.45 to 0.96, L2 7%) and clinical (OR 0.44, 95% CI 0.27 to 0.72, L2 8%); 6% of mobilization sessions involved adverse events, mostly haemodynamic changes. CONCLUSION: This review found moderate-quality evidence supporting the safety and effectiveness of early mobilization in patients with SAH. Further randomized controlled trials are needed to identify the appropriate mobilization strategy and confirm these results.
