OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory disorder characterized by progressive airflow limitation. This meta-analysis aims to evaluate the effectiveness of respiratory muscle training (RMT) on key pulmonary function parameters, inspiratory muscle strength and quality of life in patients with stable COPD. METHODS: A comprehensive search was conducted in the databases including PubMed, Cochrane, Web of Science, Embase, and ClinicalTrials...

Background Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition, yielding various respiratory symptoms and categorized under several descriptors: early, mild, young, pre-COPD, and preserved ratio impaired spirometry. COPD is synonymous with symptoms such as dyspnea and cough, in addition to others like exercise intolerance, which result from respiratory muscle weakness. Therefore, the emergence of respiratory strength assessment tools for such patients is not surprising. However, evidence is limited regarding the impact of respiratory muscle strength on the physical performance of COPD patients...

Worldwide, healthcare systems had to respond to an exponential increase in COVID-19 patients with a noteworthy increment in intensive care units (ICU) admissions and invasive mechanical ventilation (IMV). The aim was to determine low intensity respiratory muscle training (RMT) effects in COVID-19 patients upon medical discharge and after an ICU stay with IMV. A retrospective case-series study was performed. Forty COVID-19 patients were enrolled and divided into twenty participants who received IMV during ICU stay (IMV group) and 20 participants who did not receive IMV nor an ICU stay (non-IMV group)...

BACKGROUND: Previous studies have reported that maximum voluntary ventilation (MVV) may be better associated with commonly used outcomes in COPD than FEV1 and may provide information on respiratory mechanics. In this study, we aimed to investigate the relationship between MVV and clinical outcomes in COPD and to verify whether MVV predicts these outcomes better than FEV1 . METHODS: We conducted a cross-sectional study involving individuals with COPD. Lung function was assessed with spirometry; maximum inspiratory and expiratory pressures (PImax and PEmax , respectively) were assessed with manuvacuometry; and functional exercise capacity was assessed with the 6-min-walk test (6MWT)...

Pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) includes a multidisciplinary approach of exercise and pursed-lip diaphragmatic breathing. Pursed-lip diaphragmatic breathing reduces alveolar collapse during exhalation, and diaphragmatic breathing improves inspiratory pressures. Harmonica playing has maneuvers similar to those taught in pursed-lip diaphragmatic breathing, with diaphragmatic breathing to create musical tones. Hence, we designed a trial to determine whether patients with COPD would benefit from harmonica playing...

BACKGROUND: Difference between combined inspiratory and expiratory muscle training in same respiratory cycle or different cycles remained unclarified. We explored the difference between both patterns of combined trainings in patients with COPD. METHODS: In this randomized, open-label, controlled trial, stable COPD subjects trained for 48 minutes daily, for 8 weeks, using a monitoring device for quality control. Ninety-two subjects were randomly and equally assigned for sham training, inspiratory muscle training(IMT), combined inspiratory and expiratory muscle training in same cycle(CTSC) or combined inspiratory and expiratory muscle training in different cycles(CTDC)...

BACKGROUND: The primary objective of this study was to investigate whether noninvasive ventilation (NIV) can positively affect exercise capacity, maximum oxygen uptake (V̇O2 ), 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...

BACKGROUND: COPD is characterized by expiratory flow limitation, which results in symptomatic dyspnea and reduced exercise capacity. Changes in breathing mechanics mean the respiratory muscles are unable to respond to the ventilatory demands, increasing the sensation of dyspnea. A high-frequency oscillating device has been developed to improve dyspnea in patients with COPD. We conducted a feasibility trial to gain insight into the potential for recruitment, retention, and study design for a future randomized controlled trial...

Patients with chronic obstructive pulmonary disease (COPD) may have poor inspiratory muscle function, which reduces minute and alveolar ventilation, leading to increased hypoxemia and slow pulmonary oxygen uptake kinetics. However, little is known about the effect of inspiratory muscle weakness (IMW) on oxygen uptake kinetics in patients with COPD. Thus, we tested the hypothesis that COPD patients with IMW have slowed oxygen uptake kinetics. An observational study was conducted that included COPD patients with moderate to severe airflow limitation and a history of intolerance to exercise...

BACKGROUND: The aim of this study was to evaluate the efficiency of a simple prototype device for training respiratory muscles in lung function, respiratory muscle strength, walking capacity, quality of life (QOL), dyspnea, and oxidative stress in patients with COPD. METHODS: Thirty COPD patients with moderate severity of the disease were randomized into three groups: control (n=10, 6 males and 4 females), standard training (n=10, 4 males and 6 females), and prototype device (n=10, 5 males and 5 females)...

BACKGROUND: Respiratory muscle strength has been used as a tool for evaluating respiratory rehabilitation in chronic obstructive pulmonary disease. However, mouth pressure measurement evaluated by maximum expiratory mouth pressure (PEmax) or inspiratory mouth pressure (PImax) offers an indirect method for measuring respiratory muscle strength. We demonstrated the evaluation of diaphragm contractility using a mechanomyogram (MMG), which is the mechanical signal generated by the motion of the diaphragm induced by the electric stimulation of the phrenic nerve...

INTRODUCTION: Advanced air-flow limitation in patients with COPD leads to a reduction in vital capacity, respiratory muscle strength, and exercise capacity. However, its impact on chest and abdominal wall mobility is unknown. This study aimed to ascertain the prevalence of patients with COPD with reduced chest and abdominal wall mobility and to investigate the effect of reduced chest and abdominal wall mobility on pulmonary function, respiratory muscle strength, and exercise capacity...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is recognized as a multisystemic inflammatory disease associated with extrapulmonary comorbidities, including respiratory muscle weakness and cardiovascular and cardiac autonomic regulation disorders. We investigated whether alterations in respiratory muscle strength (RMS) would affect cardiac autonomic modulation in COPD patients. METHODS: This study was a cross-sectional study done in ten COPD patients affected by moderate to very severe disease...

BACKGROUND: Sniff nasal inspiratory pressure (SNIP) is a non-invasive measure of inspiratory muscle function often used as an outcome measure in clinical studies. An initial period of familiarisation with the test is recommended to minimise the learning effect. The repeatability of SNIP in patients with chronic obstructive pulmonary disease (COPD) is currently unknown. OBJECTIVES: The aim of this study was to assess the between-session repeatability of SNIP over a 3-week period in moderate-to-severe COPD patients and compare it with that of maximal inspiratory (PI max) and expiratory pressure (PE max)...

PURPOSE: We evaluated the effectiveness of intrapulmonary percussive ventilation (IPV) compared to traditional standard chest physical therapy (CPT) in patients with chronic obstructive pulmonary disease (COPD) and productive cough. METHODS: We conducted a quasi-experimental clinical trial. Twenty patients, 40% female (mean ± SD age: 70 ± 8 years), with COPD and productive cough received a multimodal respiratory treatment including IPV and CPT or a control intervention CPT for 10 days...

BACKGROUND: Inspiratory muscle training (IMT) produces beneficial effects in COPD subjects, but the effects of expiratory muscle training (EMT) and EMT plus IMT in ventilatory training are still unclear. The aim of this study was to systematically review the effects of EMT and EMT plus IMT compared to control groups of COPD subjects. METHODS: This study is a systematic review and meta-analysis. The search strategy included MEDLINE, Embase, LILACS, PEDro, and Cochrane CENTRAL and also manual search of references in published studies on the subject...

BACKGROUND: One of the major pathophysiologies in advanced chronic obstructive pulmonary disease (COPD) has been attributed to systemic inflammation. Meta-analysis of the 2005 Cochrane Database concluded the effect of nutritional supplementation alone on stable COPD was insufficient to promote body weight gain or exercise capacity. The aim of this study was to investigate the effectiveness of nutritional supplementation therapy using a nutritional supplement containing whey peptide with low-intensity exercise therapy in stable elderly patients with COPD...

BACKGROUND: Comprehensive exercise training (CET) is an efficient strategy to decrease dyspnea perception in chronic obstructive pulmonary disease (COPD) and may result in significant improvement in ventilatory muscles function. Our aim was to evaluate the effects of general exercise training on dyspnea perception and on respiratory muscles strength in COPD patients. METHODS: Consecutive COPD patients were enrolled to complete a CET programme. The patients underwent a routine that included a global warm up, upper and lower limbs endurance exercise as well as stretching and relaxation...

The present study was undertaken to evaluate the long-term effect of procaterol hydrochloride (CAS 62929-91-3, Meptin), a third generation beta2-receptor agonist on lung function, exercise capacity, health-related quality of life (HRQOL) and activities of daily living (ALDs) in patients with stable chronic obstructive pulmonary disease (COPD). Twenty patients were randomly assigned to the procaterol group or to the control group, who received oxitropium bromide (CAS 30286-75-0), an anticholinergic agent. Procaterol was inhaled three times a day at a dose of 20 pg, while oxitropium was inhaled three times a day at a dose of 200 microg...

UNLABELLED: Many authors reported respiratory muscle function impairment in patients with chronic obstructive pulmonary disease (COPD). Impaired respiratory muscle function may contribute exercise intolerance which is frequently observed in this disease. AIM OF THE STUDY: was to determine the influence of respiratory muscle function on exercise capacity in patients with COPD. METHODS: 23 patients with stable COPD aged 62.7 +/- 9.3 years (6F, 17M; mean post-bronchodilator FEV1 = 47...
