What this trial studies

This study aims to evaluate the effects of a breather device on both ventilatory and vascular functions in patients with Chronic Obstructive Pulmonary Disease (COPD) who also experience intermittent claudication. The intervention involves using an inspiratory muscle trainer to enhance muscle strength and endurance, reduce dyspnea, and improve exercise tolerance. The study will include sixty male patients aged 55-60 with specific inclusion criteria related to their COPD and leg pain. Participants will be monitored for improvements in their condition as a result of using the breather device.

Who should consider this trial

Good fit: Ideal candidates are male patients aged 55-60 with grade I or II COPD and a history of intermittent claudication.

Not a fit: Patients with cardiovascular insufficiency, recent myocardial infarction, or other serious health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the quality of life and exercise capacity for COPD patients suffering from intermittent claudication.

How similar studies have performed: While there is emerging research on the benefits of inspiratory muscle training in COPD, this specific approach targeting both ventilatory and vascular function in the context of intermittent claudication is relatively novel.
