RCT.

Age: mean (25 years); median (NR); SD (NR); range (17-33 years). Inclusion criteria: participants who were clinically stable; producing more than 20 g of sputum in 24 hours; and fit enough to carry out their own chest physiotherapy. 24 enrolled/ 24 evaluated/ 16 males (66.7% male).

The frequency of the treatment sessions varied between 2-4 per d. ACBT (gravity-assisted position): postural drainage and ACBT; including breathing control, thoracic expansion, and FET. ACBT (sitting): ACBT including breathing control; thoracic expansion; and FET. Coughing (sitting): coughing and breathing control.
Outcome measures
Outcome measures: lung function; sputum weight; oxygen saturation.
