Ambulation after Deep Vein Thrombosis: A Systematic Review
2009
ABSTRACT Purpose: To systematically review the effects of early ambulation on development of pulmonary embolism (PE) and progression or development of a new thrombus in patients with acute deep vein thrombosis (DVT). Methods: Medline, PubMed, CINAHL, EMBASE, PEDro, and Cochrane Library databases were searched from inception to June 2008. Study quality was appraised using the Jadad and PEDro scales. Meta-analyses were reported as relative risks (RR) and 95% confidence intervals (CI). Results: Four randomized trials were accepted. For development of a PE, the pooled relative risks for ambulation and compression versus bed rest and compression (RR = 0.63, 95% CI: 0.34–1.19) and for ambulation and compression versus bed rest alone (RR = 1.36, 95% CI: 0.57–3.29) were not significant. For progression of an existing thrombus or development of a new thrombus, the independent relative risks for ambulation and compression versus bed rest and compression (RR = 0.39, 95% CI: 0.13–1.14) and for ambulation and compress...
