A study concluded that the partial home program of interval-based Inspiratory Muscle Training (IMT) associated with breathing retraining (BR) is feasible and effective in patients with generalized Myasthenia gravis. Improvements in respiratory muscle strength, chest wall mobility, respiratory pattern, and respiratory endurance were observed1.
Another study concluded that specific inspiratory threshold loading training alone, or combined with specific expiratory training, markedly improved respiratory muscle strength and endurance in patients with Myasthenia gravis. This improvement in respiratory muscle performance was associated with improved lung function and decreased dyspnea. Respiratory muscle training may prove useful as a complementary therapy with the aim of reducing dyspnea symptoms, delay the breathing crisis and the need for mechanical ventilation in patients with Myasthenia gravis2.
