About this study
Official title: Impact of Pulmonary Rehabilitation on Peripheral Skeletal Muscle Function in Patients With Chronic Obstructive Pulmonary Disease.
Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airway obstruction and progressive deterioration of respiratory function. Patients with COPD show a limited exercise tolerance, early fatigability and progressive dyspnea, with important consequences on the ability to sustain even mild efforts and a drastic restriction in the activities of daily living. Muscle dysfunction is a systemic manifestation of COPD that contributes to exertion intolerance in individuals with COPD to the point of compromising fundamental functional activities, such as walking. Previous studies have shown, in fact, that quadriceps strength can be reduced by 20% to 30% in patients with COPD and this value is associated with an increased risk of mortality in patients with lower strength levels. In addition, loss of muscle mass or sarcopenia also occurs with a prevalence of between 8% and 67% in patients with COPD, exacerbating the picture of muscle dysfunction.
One of the goals of respiratory rehabilitation is precisely the prevention of muscle dysfunction in patients with COPD. However, rehabilitation programs aimed at maintaining and recovering muscle strength are often lacking in guidance regarding target muscles, duration of sessions, and training intensity, while strength assessment is often limited by the timing and resources associated with the clinical setting in which it takes place. This makes it difficult to determine its short- and long-term effectiveness.

Therefore, assessment of muscle function in patients with COPD requires tests that are simple and quick to perform, but equally capable of providing quantitative data referable to a specific characteristic of muscle strength as well as indicative of the patient's overall function. In addition, complementary measurements such as body composition and muscle mass, as well as the development of predictive models and normative values of muscle function could provide additional information on the progression of muscle dysfunction in patients with COPD, allowing rehabilitation intervention to be directed toward recovery of the most compromised functions.
Therefore, the aims of this study are: 1) To evaluate the effectiveness of a standard pulmonary rehabilitation program in recovering peripheral muscle dysfunction in patients with COPD. 2) To evaluate the clinical reliability of tests commonly used to measure peripheral muscle function in the rehabilitation setting of patients with COPD.

Clinical summary

Questions about this trial
What is this clinical trial studying?
An observational study of Copd, run by Fondazione Don Carlo Gnocchi ETS at 1 site in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Lower limbs muscle power (time frame: Change from baseline through study completion, an average of 6 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04767126, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Mar 2022.
