Chest Wall Muscle Stretching and Acute Effects in Chronic Obstructive Pulmonary Disease

Not Applicable

Completed

• Conditions: Chronic Obstructive Pulmonary Disease
• Interventions: Procedure: Stretching

• Registration Number: NCT01826669
• Lead Sponsor: Universidade Federal de Pernambuco

Brief Summary

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.

Detailed 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.

Arm && Interventions

Group	Intervention	Description
Stretching	Stretching	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.
