Effect of Pursed Lips Breathing on Chest Wall, Mobility Diaphragmatic and Exercise Tolerance in Patients With Chronic Obstructive Pulmonary Disease

Brazil14 participantsStarted 2014-03

Plain-language summary

This study aimed to evaluate the acute effect of PLB technique on diaphragmatic mobility, the kinematics of the thoracoabdominal complex analysis of lung volumes and exercise tolerance in patients with Chronic Obstructive Pulmonary Disease (COPD). This is a study randomized cross-over clinical trial and blind, in subjects with Chronic Obstructive Pulmonary Disease (COPD) according to criteria of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) (FEV1 / FVC \<0.7 and FEV1 \<80% predicted) selected at the Clinical Hospital of the Federal University of Pernambuco (UFPE) and Otavio de Freitas General Hospital (HGOF). The investigators recruited 13 patients COPD (according to previous sample calculation) aged between 40 and 80 years, of both sexes. The first day was held evaluation of lung function, respiratory muscle strength, body composition, dyspnea index and functional capacity. On the second day was held evaluation of thoracoabdominal complex kinematics by plethysmography Optoelectronics (OEP) with Quiet Breathing (QB) or pursed-lips breathing (PLB). Lung volumes with 2 minutes with QB and 6 minutes PLB or only 6 minutes by QB as randomization were observed. Before and after performing the requested breathing pattern diaphragmatic mobility was observed by Ultrasonography (US) and requested the patient an Inspiratory Capacity maneuver (IC). The evaluator who performed the ultrasound was blinded as to the beginning of the breathing pattern of order performed by the patient.

Inclusion Criteria: * COPD diagnosis with stage II-IV (GOLD), * Stable clinical condition (no exacerbation or hospital admission in the last four weeks preceding the study) * Absence of other disease that may potentially contribute to dyspnea (heart disease, congestive heart failure, neuromuscular diseases, severe postural changes) Exclusion Criteria: * BMI\> 30 kg / m2 * Musculoskeletal limitations * Use of oxygen therapy * Extreme discomfort during the procedure application

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Chest wall (Analysis of lung volumes)

Timeframe: One day during eight minutes

Mobility diaphragmatic (mobility diaphragmatic (mm) by Ultrassonography)

Timeframe: One day, before and after eight minutes of pursed lips breathing

Exercise tolerance (Glittre AVD-Test)

Timeframe: One day, for six minutes approximately. The test will be repeated after 20 minutes of rest.
