Chronic Obstructive Pulmonary Disease
Conditions
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.
Interventions
PROCEDUREStretching
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.
