Physiological Effects of Expiration With the Glottis Open in Lateral Posture (ELTGOL) and Flutter Valve in Patients With Bronchiectasis

Study Overview
=================
Brief Summary
-----------------
This study aimed to evaluate the acute physiological effects of expiration with the glottis open in lateral posture (ELTGOL) and Flutter valve in dynamic and static lung volumes in patients with bronchiectasis and, secondarily, to study the effect of these techniques in sputum production.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: FLUTTER<br>Since this was a crossover study, all patients performed all interventions in a randomized order. | Other: Flutter valve<br>* Flutter valve is a physiotherapy device commonly used for the treatment of pulmonary hypersecretive conditions. The patients is taught to exhale through the device, producing positive expiratory pressure and flow oscillations. In this study the intervention took 15 minutes. During this period the patients were free to cough.<br>|
| Experimental: ELTGOL<br>Since this was a crossover study, all patients performed all interventions in a randomized order. | Other: expiration with the glottis open in lateral posture (ELTGOL)<br>* This technique is a maneuver of slow expiration with the glottis open, with the subject in lateral posture. The patients performed three sets of 10 repetitions in left and right lateral decubitus.<br>|
| Active Comparator: CONTROL<br>Since this was a crossover study, all patients performed all interventions in a randomized order. | Other: Control<br>* Patients were instructed to stay comfortably seated during 15 minutes. After this period they were stimulated to cough during a five minutes period.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dynamic and static lung volumes | Dynamic and static lung volumes were assessed by forced spirometry and plethysmography. | In the week 1, 2 and 3. Before (baseline) and after each intervention. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sputum production | The expectorated secretions were collected using a sputum trap and quantificated by its dry weight. | Sputum was colected during the interventions |
