The Effects of Early Mobilization on Acquired Weakness in Intensive Care Units: A Literature Review

Background Intensive care unit (ICU)-acquired weakness (ICUAW) is defined as a clinical syndrome of neuromuscular weakness, and a consequence of critical illness, unrelated to any other etiology. It is associated with difficult weaning from the ventilator, prolonged ICU stay, increased mortality, and other important long-term outcomes. Early mobilization is defined as any active exercise in which patients use their muscle strength actively or passively within the first 2 to 5 days of critical illness. Early mobilization can be safely initiated from the first day of admission to the ICU during mechanical ventilation. Objectives The purpose of this review is to describe the effects of early mobilization on complications from ICUAW. Method This was a literature review. Inclusion criteria were as follows: observational studies and randomized controlled trials conducted with adult patients (aged ≥18 years) admitted to the ICU were included. Studies selected were published in the last 11 years (2010-2021). Results Ten articles were included. Early mobilization reduces muscle atrophy, ventilation, length of hospital stay, and ventilator-associated pneumonia and improves patients' responses to inflammation and hyperglycemia. Discussion Early mobilization appears to have a significant impact on the prevention of ICUAW and appears to be safe and feasible. The results of this review could be useful for improving the provision of efficient and effective tailored care for ICU patients.
