Brief 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.

Outcome Measures

Primary Outcomes (3)

  • Patients with COPD will perform the inspiratory capacity (IC) by the slow vital capacity (SVC) maneuver in order to measure dynamic hyperinflation (DH).

    Dynamic hyperinflation will be considered an increase of 150 ml or 10% on EELV after 6MST and 6MWT. End-expiratory lung volume (EELV) will be measured by the difference between total lung capacity and IC.

    Change from baseline and exactly 1 minute after the 6MST and 6MWT

  • Patients with COPD will answer dyspnea score by modified Borg scale

    Change from baseline, after the completion of each 6MST and 6MWT and exactly 1 minute after the SCC or non-SCC.

  • Patients with COPD will be monitored regarding peripheral muscle oxygenation by the near-infrared spectroscopy

    Change from baseline, after the completion of each 6MST and 6MWT and exactly 1 minute after the SCC or non-SCC.

Study Arms (2)

Slow chest compression

EXPERIMENTAL

Patients will receive the slow chest compression for one minute, immediately after 6MST.

Other: Slow chest compression

No slow chest compression

PLACEBO COMPARATOR

Immediately after 6MST, the patient will not receive the SCC and will remain seated at rest for one minute, without any intervention.

Other: No slow chest compression

Interventions

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".

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".

No slow chest compression
