Intensive care unit-acquired weakness (ICUAW) is one of the leading causes of morbidity in critically ill patients and a significant risk factor for the development of chronic critical illness. In 2008, 727,000 patients were hospitalized for sepsis, with mortality rate of 17% at an estimated cost of $14.6 billion [1]. The risk of critical illness neuromuscular abnormalities in patients with sepsis, multiorgan failure, or prolonged mechanical ventilation is reported to be as high as 46% [2].
