"Daily physical activity" and "copd"

Most pulmonary rehabilitation (PR) programs have had to adapt due to the COVID-19 pandemic and associated restrictions. Current alternative home-based programs have limitations and require modification. In this paper, we outline a novel method to monitor home-based PR programs, which has the potential to improve PR safety and efficacy. This new method is based on a remote patient monitoring (RPM) system with connected smart devices that enables the Respiratory Therapist (RT) to have real-time access to patient data including heart rate and peripheral oxygen saturation during exercise...

Knowledge about modifiable determinants of daily physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) is crucial to design effective PA interventions. The present study aimed to determine the contribution of quadriceps strength, power and endurance to daily PA in COPD. Additionally, for quadriceps endurance, we also aimed to determine to what extent the association varies according to the mode of movement (isotonic, isometric, or isokinetic). Using a multicentre cross-sectional trial design we determined the contribution of quadriceps function to daily PA (steps, sedentary time and time spent doing moderate-to-very-vigorous physical activity [MVPA]) using bivariate and partial Pearson correlation analysis (r) and multiple linear regression models (ΔR2 )...

BACKGROUND: The prevalence of physical frailty and its clinical characteristics in advanced chronic obstructive pulmonary disease (COPD) is unknown, as well as the usefulness of functional capacity tests to screen for physical frailty. The aim of the study was to evaluate the proportion and clinical portrait of COPD patients with chronic respiratory failure exhibiting physical frailty at the time of referral to home-based pulmonary rehabilitation. We also evaluate the usefulness of the short physical performance battery (SPPB) and timed-up and go (TUG) as potential screening tools for physical frailty...

INTRODUCTION: Patients with COPD are vulnerable to workforce detachment. Better knowledge of features associated with paid work loss might be of help to design and select appropriate interventions. METHOD: This cross-sectional study aimed to explore the presence of treatable traits in COPD patients without paid work. Patients with COPD below 65 years at first referral to a hospital-based patient clinic were included. Using binary logistic regression analysis, the relationship between paid work and the following characteristics was explored: low daily physical activity, exercise, active smoking, Medical Research Council dyspnea scale (MRC), poor nutritional status, exacerbations, and fatigue (checklist individual strength (CIS))...

BACKGROUND: Measuring daily physical activity and exercise capacity is recommended in the routine care of patients with chronic obstructive pulmonary disease (COPD). The 4-m gait speed (4mGS) is simple and effective in stratifying patients according to exercise performance, dyspnea, health status, and prognosis. We assessed the reliability of the 4mGS as a clinical marker by examining its association with established clinical indicators among hospitalized patients with COPD. METHODS: This retrospective study included 78 patients hospitalized with COPD (mean age: 76...

BACKGROUND: Daily physical activity is reduced in patients with chronic obstructive pulmonary disease (COPD) and a reduced level of physical activity has been shown to be an important predictor for the prognosis, such as increased risk of exacerbation and mortality. However, there has not yet been a useful biomarker of the physical activity. In our previous cross-sectional study, we showed that the level of one of the possible myokines, which is an anti-aging factor, growth differentiation factor 11 (GDF11), was decreased in the plasma from patients with COPD and correlated with the physical activity...

Background: Pulmonary Rehabilitation (PR) is an important therapy for patients with COPD, yet uptake remains low. Intervention strategies which recapitulate the benefits of PR are therefore needed, and digital, home-based therapies present opportunity in this space. Digital therapies also potentially offer an opportunity to standardize PR in clinical trials for new COPD therapies. Aims and Methods: We aimed to create a digital application (App), Respercise®, consisting of up to 4 strengthening exercises in conjunction with Therbands and a daily physical activity program with individualized step goals, and to test its feasibility in a clinical trial...

BACKGROUND: Clinical control in chronic obstructive pulmonary disease (COPD) has not been completely characterized. A proposal of clinical control criteria (CCC) has been recently defined and validated as a tool for determining control, but there is scarce information on patients with severe COPD. OBJECTIVE: To evaluate clinical control in severe COPD using the CCC. PATIENTS AND METHODS: The study design was observational, multicenter, cross-sectional study involving 4801 patients with severe COPD in Spain...

The appropriate titration for the personalized oxygen needs of patients with chronic obstructive pulmonary disease (COPD) and severe hypoxemia is a determining factor in the success of long-term oxygen therapy. There are no standardized procedures to assist in determining the patient's needs during the physical activities of daily life. Despite that effort tests are a wide broad approach, further research concerning the development of protocols to titrate O2 therapy is needed. The main objective of this study was to assess whether the level of oxygen titrated through the 6-minute walking test (6MWT) for patients with COPD and exertional hypoxemia is adequate to meet the patients' demand during their activities of daily living...

BACKGROUND: The ageing population in most low-and middle-income countries is accompanied by an increased risk of non-communicable diseases culminating in a poor quality of life (QOL). However, the factors accelerating this poor QOL have not been fully examined in Nepal. Therefore, this study examined the factors associated with the QOL of older adults residing in the rural setting of Nepal. METHODS: Data from a previous cross-sectional study conducted among older adults between January and April 2018 in in rural Nepal was used in this study...

Background: The 3-minute constant-rate stair stepping (3-min CRSST) and constant-speed shuttle tests (3-min CSST) were developed to assess breathlessness in response to a standardized exercise stimulus. Estimating the rate of oxygen consumption (V'O2 ) during these tests would assist clinicians to relate the stepping/shuttle speeds that elicit breathlessness to daily physical activities with a similar metabolic demand. This study: (I) developed equations to estimate the V'O2 of these tests in people with chronic obstructive pulmonary disease (COPD); and (II) compared the newly developed and American College of Sports Medicine (ACSM) metabolic equations for estimating the V'O2 of these tests...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is airway inflammation characterized and low daily physical activity. Most pulmonary rehabilitation (PR) programs are often provided to stable patients, but fewer training programs are specific for hospitalized patients with acute exacerbation (AE). Patients with AECOPD experience increased dyspnea sensations and systemic inflammation during exercise training. High-flow nasal therapy (HFNT) reduces the minute volume, lowers the respiratory rate, and decreases the work of breathing...

Purpose : To compare the effects of three modalities of resistance training, two using elastic components and one using conventional weight machine on peripheral muscle strength in Individuals with chronic obstructive pulmonary disease (COPD). Effects on exercise capacity, impact of disease on health status, body composition and daily level of physical activity were investigated as secondary endpoints. Methods : Forty-eight participants were randomly allocated (Trials Registry #RBR-6V9SJJ) into Elastic band group (Theraband®) (EBG), Elastic tubes training using Lemgruber® (ETG), and Conventional training with weight machine equipment (CG)...

PURPOSE: To determine the effects of providing a wheeled walker (WW) for use in the home and community, on daily physical activity (PA) and sedentary time (ST) in people with chronic obstructive pulmonary disease (COPD). METHODS: A randomised cross-over study in which participants with COPD characterised by a 6-min walk distance ≤ 450 m, who had recently finished pulmonary rehabilitation, completed two 5-week phases. During one phase, participants were provided a WW to use, whereas during the other phase, the WW was not available...

INTRODUCTION: Functional training has been shown to be a viable alternative for the elderly and patients with chronic obstructive pulmonary disease (COPD). However, whether the combination of this type of training with aerobic and resistance training, commonly performed in pulmonary rehabilitation (PR) programs, induces more pronounced effects on daily physical activities and functionality remains unclear. The aims of the study will be to evaluate the short-term and sustained effects of the combination of a functional circuit program with a training program consisting of aerobic and resistance exercise...

Background: Low physical activity in patients with chronic obstructive pulmonary disease (COPD) is associated with increased morbidity and mortality. To inform the design of a home-based physical activity promotion program for patients with COPD recently discharged from a minority-serving hospital, we conducted a cohort study to evaluate objectively measured daily physical activity and patient-reported outcomes. Methods: This was a 12-week prospective cohort study of patients with a physician diagnosis of COPD recently hospitalized (≤ 12 weeks) for respiratory symptoms...

Chronic obstructive pulmonary disease (COPD) can sometimes be associated with skeletal muscle atrophy. Hypoxemic episodes, which occur during disease exacerbation and daily physical activity, are frequent in COPD patients. However, the link between hypoxemia and muscle atrophy remains unclear, along with mechanisms of muscle hypoxic stress response. Myogenic progenitors (MPs) and fibro/adipogenic progenitors (FAPs) express CD34 and participate to muscle mass maintenance. Although there is evidence linking CD34 expression and muscle repair, the link between CD34 expression, muscle wasting and the hypoxic stress observed in COPD has never been studied...

Supervised exercise training (EXT) as part of pulmonary rehabilitation is arguably the most effective intervention for improving exercise tolerance in patients with chronic obstructive pulmonary disease (COPD). In the current review, we focus on the physiological rationale for EXT and the expected physiological benefits that can be achieved in patients who can be exposed to sufficiently high training stimuli. Thus, after a brief consideration of the mechanisms of exercise limitation and their sensory consequences, we expose the potential beneficial effects of EXT on respiratory mechanical and peripheral muscular adaptations to exercise...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) leads to peripheral and respiratory muscle dysfunctions. Nowadays, inspiratory muscle training can be geared toward strength or endurance gains. This study aims to investigate the effects of an inspiratory muscle training (IMT) protocol using different therapeutic modalities to be implemented in pulmonary rehabilitation programs. The effects of IMT on exercise capacity were considered as the primary endpoint, and the effects of IMT on inspiratory muscle function, health-related quality of life, and daily physical activity level were considered as the secondary outcomes...

BACKGROUND: Assist use of inhaled short-acting beta 2 agonists (SABAs) is reportedly effective for preventing shortness of breath on exertion in chronic obstructive pulmonary disease (COPD) patients. However, it is unclear what strategy would be useful for improving physical activity in such patients. The aim is to investigate the effects of assisted use of SABA (procaterol) on physical activity in Japanese COPD patients targeting patient-specific restrictions in daily behavior. METHODS: Fourteen patients with stable COPD (age: 72...
