COPD, Respiratory Muscles, Training
Conditions
Brief summary
Respiratory muscle weakness and fatigue are related to clinical deterioration in patients with Chronic Obstructive Pulmonary Disease (COPD). Respiratory muscle training (RMT) is a key therapeutic strategy in these patients. It is necessary therefore to increase its dissemination on a large scale, improve patient´s adherence and optimize the control of the implementation of training. The aim of this project was to design a RMT device including light and sound incentives, digital registration application and analysis of the training sessions, and studying the effectiveness of a new shortened RMT scheme of high intensity that could provide added value to enhance the implementation of training in patients with COPD. From an operational point of view, researches were organized into three packages of complementary work focused on the design of a new portable dual valve with electronic lighting and auditory incentives components. The conceptualization and design of a software to analyze the performance and individual continuous use of the valve, and the evaluation of the feasibility, safety and efficacy of a shortened schedule of respiratory muscle training in adult patients with COPD were realized.
Interventions
OTHERRespiratory muscle training
General high-intensity training consists in maximum effort intervals of 30 seconds duration against an equivalent resistance 0.075 kg / kg of body mass followed by a recovery period of 4 minutes cycle ergometer; the total duration was 3 weeks. They were made in this regard, five weekly sessions of 30 minutes per session, Additionally, randomly, the patients were divided into one of 3 possible groups of respiratory training, which consisted of 5 sets of 10 full breaths (inspiration and expiration) in the morning and afternoon during 3 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Respiratory muscle strength assessed by Maximun Respiratory Pressure | From baseline to 3 weeks | Defined as the ability to make a maximum respiratory effort, it was assessed using the MicroRPM® device. This test is to generate the maximum inspiratory pressure (from residual volume) and expiratory (from total lung capacity) against a road or occluded team, performing the maneuver by keeping the mouth and nose occluded. |
| Change in Exercise Capacity assessed by cardiopulmonary exercise testing | From baseline to 3 weeks | — |
| Change in Quality of life assessed by Quality of life Short Form 36 questionnaire | From baseline to 3 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Change in Exercise Capacity assessed by Six minutes walking Test | From baseline to 3 weeks |
| Change in Respiratory function assessed by spirometry | From baseline to 3 weeks |
