Acute Effects of a Stretching Program of the Rib Cage Muscles on Patients With COPD During Exercise

Acute Effects of a Stretching Program of the Rib Cage Muscles on the Regional Distribution of Ventilation and the Diaphragmatic Mobility of Patients With COPD During Exercise: a Randomized Crossover Clinical Trial

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

Study Overview

• Status: Unknown
• Conditions: Pulmonary Disease, Chronic Obstructive
• Intervention / Treatment: Other: Stretching; Other: Exercise; Other: Control

Detailed 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.

• Study Type: Interventional
• Enrollment (Anticipated): 20
• Phase: Not Applicable

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 50 years to 80 years (Adult, Older Adult)

Description

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Stretching and Exercise; This group undergo a session of stretching aiming flexibility of the rib cage and later at an exercise test with constant load up to the limit of tolerance for exercise bike	Other: Stretching; Stretching of the rib cage muscles; Other: Exercise; Constant load exercise on a bike
Sham Comparator: Control and Exercise; This group will carry out the exercise test with constant load up to the limit of tolerance for exercise bike after a period of rest under the same environmental conditions and the experimental group time. During this time the therapist will place their hands but not performing the stretch.	Other: Exercise; Constant load exercise on a bike; Other: Control; Rest without stretching (sham)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Endurance tolerance as measured by the duration of the exercise	Participants will be followed for the duration of the exercise, an expected average of 10 minutes
Dyspnea as measured by Borg Escale	Participants will be followed for the duration of the exercise, an expected average of 10 minutes

Secondary Outcome Measures

Outcome Measure	Time Frame
Diaphragm mobility measured by ultrasound	Participants will be followed for the duration of the stretching and the exercise, an expected average of 60 minutes
Volumes of the chest wall measured by pletismography optoelectronic	Participants will be followed for the duration of the stretching and the exercise, an expected average of 60 minutes
Muscle electrical activity measured by surface electromyography	Participants will be followed for the duration of the stretching and the exercise, an expected average of 60 minutes
