Neurological dysfunction is a common condition necessitating prolonged mechanical ventilation (PMV). Among patients with acute neurological diseases, 17% to 33% are intubated and mechanically ventilated for respiratory failure. Patients with acute neurological diseases requiring MV generally have adverse outcomes with a hospital mortality rate among patients with such diseases has been reported to be in the range of 16-33%. Inspiratory muscle weakness is common in patients receiving mechanical ventilation, especially patients with prolonged duration of mechanical ventilation. Inspiratory muscle training could limit or reverse these unhelpful squeal and facilitate more rapid and successful weaning.Hence, the importance of physical therapy emerged in helping patients to be weaned from ventilators by using various methods to strengthen the respiratory muscles in different ways.
