Purpose: To verify the number of patients with COPD responders to two different home-based rehabilitation programs.
Methods: This was a blinded, randomized, and controlled clinical trial. The six-minute step test (6MST), one-minute sit-stand test (1-MSTST), six-minute walk test (6MWT), COPD Assessment Test (CAT), modified Medical Research Council (mMRC), monitoring of physical activity in daily life, and isometric quadriceps muscle strength were assessed pre- and post-intervention.
Background: The primary objective of this study was to investigate whether noninvasive ventilation (NIV) can positively affect exercise capacity, maximum oxygen uptake (V̇ ), and symptoms after a 6-week physical training program for subjects with moderate to very severe COPD.
Methods: 47 subjects with COPD who were enrolled in a physical training program were randomized to either physical training alone or NIV + physical training (NIV-Physical training). Physical training consisted of dynamic aerobic exercises on a treadmill 3 times/week for 6 weeks, for a total of 18 sessions.
Objective: To evaluate the responsiveness of the six-minute step test (6MST) to an aerobic physical training program (PTP) and to determine the efficacy of the PTP regarding spirometric variables during the 6MST, as well as physical performance, sensation of dyspnea, and SpO2 during the 6MST and the six-minute walk test (6MWT), in patients with COPD.
Methods: This was a controlled, prospective randomized study involving patients clinically diagnosed with COPD, with an FEV₁/FVC ratio < 70%, and having been clinically stable in the last two months. The patients were randomized to undergo a PTP on a treadmill, three times a week, for six weeks (PTP group) or not (control group).
Background And Purpose: Individuals with chronic obstructive pulmonary disease (COPD) present reduced peripheral muscle strength, which leads to impaired mobility and increased mortality risk. However, it is not clear whether there is any relationship between muscle strength, muscle mass and the body mass index, airflow obstruction, dyspnea, exercise performance (BODE) index scale, which is considered to be the best predictor of survival for individuals with COPD. The BODE Index is a multidimensional system that measures body composition (B), airway obstruction (O), dyspnea perception (D) and the ability to exercise (E), and rates the severity of the major changes found in individuals with COPD.

Methods: A total of 243 volunteers (123 females and 120 males; 20-70 years of age) participated in the study. The PEF measurements were performed with the volunteer standing, using a nose clip, by means of a portable peak flow meter.
Aim: To verify the outcome of different physical therapy interventions in activities of daily living of individuals with chronic obstructive pulmonary disease (COPD).
Methods: Twenty-two COPD individuals were randomly divided into three groups: the Lower Limb Training Group (LLTG, n=8) performed treadmill exercise, Upper Limb Training Group (ULTG, n=8) performed upper limb (UL) training, and Control Group (CG, n=6) underwent bronchial hygiene therapy for 6 weeks, three times per week. The following were simulated in the activities of the daily living test: blackboard erasing, weight lifting exercise, stair climbing and treadmill walking.
