In ICU, patients are frequently exposed to prolonged immobilization
ICU acquired neuromuscular complication are common, debilitating and long lasting.
Contribution of bed rest to the development of ICU acquired weakness is associated with – prolonged mechanical ventilation, – longer ICU stay and – longer recovery time – Marked decline in functional status
