About

The study hypothesis is chest wall muscle stretching increase distribution of volume variation of thoracoabdominal wall and reduce electromyographic activity of respiratory muscles in patients with Chronic Obstructive Pulmonary Disease.

Full description

Randomized controlled trial involving patients with Chronic Obstructive Pulmonary Disease evaluated before and immediately after a program of stretching muscles of the rib cage or after resting with time similar to the intervention, as volume variation of thoracoabdominal wall by optoelectronic plethysmography and on the electromyographic activity of accessory muscles of respiration.

Stretching

Active Comparator group

Description:

The respiratory muscle stretching were developed bilaterally as follows: * Upper trapezius: head lateral flexion with a hand therapist supports the the occipital region and his shoulder, promotes the stretching; * Sternocleidomastoid: was stretched with flexion lateral and rotation of the head to the side which hands on the occipital region and in the sternal region; * Scalene: with one hand on the occipital region and the other in the sternum, the two points was stretched; * Pectoralis major: the arm was abducted, flexed the forearm and hand was in the occipital region the therapist hands in the arm and in the side of the upper chest, which was stretched craniocaudal direction; * Intercostal: therapist performs with both hands to mobilize and stretch the ribs in cranial-caudal directions.

Treatment:

Procedure: Stretching

Rest

No Intervention group

Description:

COPD patients were not submitted to any intervention, remaining at rest in the same place, position and time period to the treatment group.
