BACKGROUND Extracorporeal membrane oxygenation (ECMO) is mainly applied to patients with significant cardiorespiratory failure who do not respond to existing conventional treatments. Patients that are supported with veno-arterial ECMO (VA-ECMO) are considered very-high risk patients to participate in any type of physical therapy (PT) or mobilization. However, cumulative evidence suggests that early mobilization of critically ill patients is feasible, safe, and efficient under certain circumstances. AIM To summarize the existing evidence on the impact of early mobilization and physiotherapy on VA-ECMO patients. METHODS This is a scoping review that used systematic electronic literature searches (from inception until January 2025) on MEDLINE (PubMed), PEDro, DynaMed, CINAHL, Scopus, Science direct and Hellenic Academic Libraries. Snowball searching method was also applied. Eligible studies included those reporting patients on VA-ECMO who participated in early mobilization or PT, published in English and utilized any primary evidence study design. Studies on children, animals and patients placed on any other ECMO, secondary evidence, and ‘grey’ literature were excluded. RESULTS A total of 316 articles were retrieved and 13 were included in the study. Of those, 1 study was a randomized control trial, 4 retrospective studies, 4 retrospective cohort studies, 1 case series and 3 case reports. The sample size of the included studies ranged from 1 to 104 VA-ECMO patients, who were ambulated or received PT interventions, and mobilization frequency ranged from 2 per day to 4 per week. Mobilization of VA-ECMO patients seems to be safe regardless the cannula’s position. PT and early mobilization were associated with better weaning from mechanical ventilation, gradual reduction of inotropes and functional capacity improvement after ECMO discharge. CONCLUSION Early mobilization in VA-ECMO seems to be safe and can potentially help reduce vasoconstrictors and speed up rehabilitation times. High quality research on early mobilization in VA-ECMO patients is warranted.
