Clinical Trial Summary

Investigate the effects of stretching the muscles of the rib cage in individuals with COPD during exercise.

Description:

To investigate the effects of a stretching program for the muscles of the rib cage or control in patients with COPD during exercise and / or the immediate post-exercise, using the following parameters:

• Tidal volume (VT), respiratory rate (RR), minute volume (MV), inspiratory time (Tins) and expiratory (T exp).

• Change in volumes of total and regional chest magazines (pulmonary rib cage, abdominal rib cage and abdomen).

• Diaphragmatic mobility.

• electrical muscle activity

• endurance time.

• Dyspnea sensation.

Recruitment information / eligibility

• Enrollment: 20
• Est. completion date: November 2015
• Est. primary completion date: October 2015
• Accepts healthy volunteers: No
• Gender: Both
• Age group: 50 Years to 80 Years

Eligibility

Inclusion Criteria:

• Smoking history, occupational or environmental exposure to pollutants and / or symptoms of cough, dyspnea or hypersecretion;

• FEV1 <80% predicted and post-bronchodilator FEV1 / FVC <70% to confirm the diagnosis of airway obstruction not fully reversible bronchodilator therapy;

• Absence of co-morbidities that does not allow the realization of stress (hypertension, severe pulmonary hypertension, myocardial infarction, congestive heart failure, severe dyspnoea);

• Preserved cognitive functioning;

• Sedentary

• Clinically stable during the study period.

Exclusion Criteria:

• Patients with cognitive, hearing or visual deficit;

• Changes in the neuro-musculo-skeletal system which endangers or impairs the assessment;

• Obese

• Not be able to achieve at least three stages of the incremental test.
