Many critically ill patients undergo a period of immobilization with detrimental effects on skeletal muscle, effects which seem most pronounced in the first days of critical illness. Diagnosis of intensive care unit muscle weakness (ICUAW) is often made after discontinuation of sedation when significant nerve and/or muscle damage may already have occurred. Recently, there has been interest in early mobilization during the acute phase of critical illness, with the goal of preventing ICUAW. Neuromuscular electrical stimulation (NEMS) is an alternative form of exercise that has been successfully used in patients with advanced chronic obstructive pulmonary disease (COPD) and chronic heart failure. NEMS is a rehabilitation tool that can be used in critically ill, sedated patients, does not require patient cooperation, and is therefore a promising intervention to prevent muscle dysfunction in the critically ill. When applied early during the course of critical illness, NEMS can preserve muscle morphology and function. Available evidence suggests that NEMS may have a preventive role in the development of ICUAW and could even contribute to a shorter duration of weaning from mechanical ventilation. Studies are needed to evaluate the long-term effect of NEMS and to explore NEMS settings and delivery characteristics most appropriate for different subgroups of critically ill patients.
