ICU-acquired weakness is diagnosed in approximately 1 million mechanically ventilated patients annually.1 This weakness is secondary to multiple mechanisms including myopathy, neuropathy, deconditioning and protein malnutrition. In addition, ICU-acquired weakness is associated with decreased quality of life and increased mortality.2 Physical rehabilitation and nutritional support have the potential to improve muscle strength and help maintain functional status.
