The use of autogenic drainage (AD) in patients with cystic fibrosis (CF) has been officially approved; therefore, the purpose of this study was to compare the efficiency of the leading therapeutic techniques based on AD in patients with CF; Among patients with CF assessments were made of spirometric parameters, percent blood oxygen saturation, and the general feeling of the patients (Borg, VAS, and mMRC dyspnea scale) before and after therapy using AD, using AD in connection with a belt or a Simeox device and AD in combination with both a belt and Simeox device simultaneously. The best therapeutic effects were generated by the combination of AD with the belt and with the Simeox device. The greatest improvements were observed for FEV1, FVC, PEF, FET, saturation, and patient comfort. In patients <10.5 years of age, the increase in the level of FEV3 and FEV6 was significant in comparison to older patients. Due to their efficacy, therapies connected with AD should be applied not only in hospital departments but also during daily patient care. Given the particular benefits observed in patients <10.5 years of age, it is important to guarantee real accessibility to this form of physiotherapy, especially in this age group.
