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.

Conditions

Chronic Obstructive Pulmonary Disease

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: FACTORIAL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

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.

Group Type: ACTIVE_COMPARATOR

Stretching

Intervention Type: PROCEDURE

Patients submitted to respiratory muscle stretching related to the increase thoracic mobility. Stretching were performed in the upper trapezius, scalenes, sternocleidomastoids, major pectoral and intercostals. The muscle stretching were performed passively by a single therapist trained and experienced. The subjects were positioned supine or lateral, knees flexed in order to correct the lumbar curve. Stretching occurred during the expiratory phase, leading to muscle maximum length, with two series of ten consecutive incursions for each muscle, with an interval of one minute between series. The patients were properly informed to perform slow exhalations and pursed-lip during stretching.

Rest

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

Group Type: NO_INTERVENTION

No interventions assigned to this group
