Study design: a randomized, crossover trial. Each patient performed three different airway clearance techniques (Autogenic drainage, slow expiratory with glottis opened in lateral posture [ELTGOL], temporary- positive expiratory pressure [T-PEP] with not similar autonomy degree in a randomized order. Each technique were applied in 3 sessions during one week at alternate days (Monday /Wednesday/Friday or Tuesday/Thursday/Saturday). The time spent in each bronchial session was 40 minutes. Seven days were the wash-out time period between the different techniques.

| Autogenic drainage | Other | It was performed following J. Chevallier recommendations.In this trial it was considered a self-administrated technique because physiotherapist only gave oral advice in order to ensure a correct performance of the technique. |
| Measure | Description | Time Frame |
|---|---|---|
| Weight of sputum expectorated during each airway clearance therapy session | Wet weight sputum production were recollected in one pre-weighted containers. It was measured in grams. | 40 minutes |
| Weight of sputum expectorated 24 hours post each bronchial session | Wet weight sputum production were recollected in one pre-weighted containers. It was measured in grams. | 24 hours |

| Slow expiration with glottis opened in lateral posture | Other | It was performed following Postiaux´s recommendations. In this trial the technique was considered active-assisted because the physiotherapy played a role important in their execution. |
|
|
| Temporary-positive expiratory pressure | Other | The diaphragmatic breathing was required for this technique whereas patients remain seated in front of the device with a nose clip. The inspiratory /expiratory ratio was 1:2.It was taken into account as a device-administrated technique for this trial. |
