Summary

Background: Commonly, patients with chronic obstructive pulmonary disease (COPD) present dyspnea, dynamic hyperinflation (DH) and important peripheral muscle deoxygenation when performing their activities of daily living (ADLs). The slow chest compression (SCC) technique is a physiotherapy strategy that could maybe reduce DH, dyspnea and peripheral muscle deoxygenation in patients with COPD. The aim of the study is to analyse the effects of SCC in DH, dyspnea and peripheral muscle deoxygenation induced by exercise tests. The secondary objective was to identify responders and non-responders to the technique.

Design: Randomized cross-over study. Setting: The study will be conducted in an outpatient pulmonary rehabilitation program in Florianopolis, Brazil

Subjects: Patients with COPD (GOLD 2-4).

Interventions: Patients will randomly receive or not the SCC after six-minute step test (6MST-SCC and 6MST-NonSCC).

Main measures: At baseline and 1 minute after the tests, the inspiratory capacity (IC) will be assessed by the slow vital capacity (SVC) maneuver. At baseline, immediately after, and 1 minute after the tests, the dyspnea score will be assessed. The physiological responses and the peripheral muscle deoxygenation will be assessed during the tests and 1 minute after them.

Conditions

Interventions

OTHER

Slow chest compression

During the SCC, the patient will remain in the sitting position; a bimanual slow compression on his/her upper chest will be performed always by the same evaluator, who will stand behind the patient. This compression will be done only in the expiratory phase, during one minute, in all respiratory cycles, respecting the chest mobility of each patient. A standardized verbal command will be given: "Exhale all the air".

OTHER

No slow chest compression

The patient will remain seated at rest for one minute after the 6MST. A standardized verbal command will be given: "Exhale all the air".
