The aim of this study To show the effect of breather on ventilatory and vascular function in COPD patient with intermittent claudication.
recent researches show that COPD patients have risk of developing peripheral arterial disease (PAD) which represented on patient by intermittent claudication inspiratory muscle trainer as the breather device show increasing in inspiratory muscle strength and endurance; reduction of dyspnea; and improving of exercise tolerance .
Because of all this things this study tends to show the effect of the breather on ventilatory and vascular function in COPD patient with intermittent claudication.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| treatment group | Experimental | This group include 30 patients with COPD and intermittent claudication. These patients can receive aerobic exercise (by applying treadmill exercise for 20 min) and inspiratory muscle training (by using The BREATHER device with Light/Medium resistance for 3-5 sets /session), for 4 weeks (3 sessions per week) and pursed lip breathing. |
|
| control group | Active Comparator | This group include 30 patients with COPD and intermittent claudication. These patients can receive pursed lip breathing and aerobic exercise (by applying treadmill exercise for 20 min) with the usually pharmacological treatment, for 4 weeks (3 sessions per week). |

| The BREATHER | Device | The BREATHER is Light/Medium resistance inspiratory muscle trainer which has significance role in increasing inspiratory muscle strength and endurance which could result in a decreased sensation of dyspnea |
| Measure | Description | Time Frame |
|---|---|---|
| Ventilatory function: by spirometry test | Spirometry is a physiological test that measures the ability to inhale and exhale air relative to time. | 4 weeks |
| Vascular function: by doppler ultrasound | Doppler ultrasound is a simple and non-invasive and method for the evaluation of early atherosclerosis. It can be used as a screening program for PAD in populations with high risk for atherosclerosis. | 4 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Functional capacity assessment: by 5 repetitions sit to stand test (5R-STS) | (5R-STS) test is an objective test of functional impairment commonly used in various diseases including COPD which is used to measure the severity of disease and to monitor recovery. | 4 weeks |
| Treadmill exercise testing |
