Summary
A 12-month home-based strength training program did not improve dyspnea in COPD patients but enhanced exercise capacity. This program was well-accepted and may support continued exercise post-rehabilitation.
Area of Science:
- Pulmonary Medicine
- Rehabilitation Science
- Exercise Physiology
Background:
- Most patients with Chronic Obstructive Pulmonary Disease (COPD) struggle to maintain exercise training after completing pulmonary rehabilitation (PR).
- Lack of sustained exercise can negatively impact patient outcomes and quality of life.
Purpose of the Study:
- To evaluate the 12-month effectiveness of a home-based, minimal-equipment strength training program on dyspnea, exercise capacity, and patient-reported outcomes in COPD patients post-PR.
- To assess patient adherence and acceptance of the home-based exercise program.
Main Methods:
- A parallel-arm, multicenter randomized controlled trial involving 123 COPD patients (61 intervention, 62 control).
- The intervention group (IG) performed a home-based strength training program, while the control group (CG) received usual care.
- Primary outcome: change in Chronic Respiratory Questionnaire (CRQ) dyspnea score. Secondary outcomes: exercise capacity (1-min sit-to-stand-test [1MSTST], 6-min walk test [6MWT]), quality of life, exacerbations, and symptoms.
Main Results:
- No significant difference in CRQ dyspnea score change between groups over 12 months.
- Moderate evidence of improvement in 1MSTST repetitions in the IG compared to the CG (P=0.033).
- 79% of IG participants reported positive effects attributed to the training, indicating good acceptance and perceived benefits.
Conclusions:
- The home exercise program did not significantly reduce dyspnea but improved 1MSTST performance and patient-perceived fitness in COPD patients.
- The supported home-based strength training program was well-accepted and may facilitate sustained exercise engagement following pulmonary rehabilitation.

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
2.9K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
