RMT has proven beneficial in some studies in patients with CF. Especially in combination with exercise, RMT may increase your respiratory muscle strength, exercise tolerance, and oxygen uptake. In addition, RMT may reduce the frequency of exacerbations (Santana-Sosa et al. 2014; McIlwaine et al. 2013). As RMT strengthens cough effectiveness and sputum expectoration, it may be specifically powerful in combination with an oscillatory device, which loosens mucus, to optimize the discharge of secretions.
