Other Clinical Trial - Effects of Pulmonary Rehabilitation on Respiratory

Status Completed

Clinical Trial Summary

The effect of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD) has been based on systemic outcome measures, however, little is known about the effectiveness of this intervention on patients' lung function. The forced expiratory volume in one second (FEV1), despite of being the gold standard for assessing lung function in COPD, is poorly responsive to pulmonary rehabilitation. Thus, an objective and responsive outcome measure to assess the effect of pulmonary rehabilitation on lung function is needed.

Computerized respiratory sounds have been found to be a more sensitive indicator, detecting and characterizing the severity of respiratory diseases before any other measure, however its potential to detect changes after pulmonary rehabilitation has never been explored. Therefore, this study aims to assess the effects of pulmonary rehabilitation on the characteristics of computerized respiratory sounds in patients with COPD.

A randomized controlled study with one group undergoing pulmonary rehabilitation (n=25) and other group receiving standard care (n=25) will be conducted. The pulmonary rehabilitation program will included exercise training (3*week) and psychoeducation (1*week).

Computerized respiratory sounds, lung function, exercise capacity, quadriceps muscle strength, health-related quality of life and health services use will be assessed in both groups, at baseline, immediately post-intervention and at follow-ups (3 and 6 months after PR).

Descriptive and inferential statistics will be used.

It is expected that significant changes occur on the characteristics of computerized respiratory sounds in patients enrolled in the pulmonary rehabilitation group, in comparison with patients receiving standard care. Thus, computerized respiratory sounds could provide a simple, objective and non-invasive measure to assess lung function changes after pulmonary rehabilitation.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
