Other Clinical Trial - The Inspiratory Muscle Activation Pattern &

Status Completed

Clinical Trial Summary

The purpose of this study is to assess the activation patterns of diaphragm and sternocleidomastoid (SCM) muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Null hypothesis (H0): There is no significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. Alternative hypothesis (H1): There is significant difference between activation pattern of diaphragm and SCM muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation.

Clinical Trial Description

The prevalence of chronic obstructive pulmonary disease (COPD) is 11.7% around the world, and it is expected to rise over the next 30 years. In Taiwan, COPD is estimated as the seventh leading cause of death in 2016, and has been gradually increasing in the past decades. COPD has been long considered to be a disease state characterized by airflow limitation that are not fully reversible, leading to abnormalities in control of breathing, worsening of respiratory mechanics and pulmonary function. However, COPD is no longer considered to affect only the lungs and airways, but also the rest of the body including decreases in respiratory and limb-muscle mass and function. When acute exacerbation occurs, lung function decreases rapidly. According to the previous studies, inspiratory muscle training (IMT), can improve the strength and endurance of the diaphragm, reduce dyspnea and breathing pattern, thus increasing the capacity of activities tolerance in patients with COPD. Although more and more studies are focus on diaphragm weakness and the effect of IMT in patients with COPD, the efficacy and intensity of IMT in patients with COPD is still controversial and the clinical use is limited. Whether increases intensity during IMT would lead to improvements in contraction pattern of respiratory muscle remained unclear. Therefore, the purpose of this study is to assess the activation patterns of diaphragm and sternocleidomastoid (SCM) muscle during different loaded inspiratory muscle performance in patients with COPD after acute exacerbation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
