Chronic obstructive pulmonary disease (COPD) is a common and treatable disease characterized by progressive airflow limitation and tissue destruction. It is associated with structural lung changes due to chronic inflammation from prolonged exposure to noxious particles or gases most commonly cigarette smoke.
POWERbreathe device (POWER-breathe International Ltd., Southam, Warwickshire, UK) is an inspiratory muscle training and this device has recently shown benefits on pulmonary function. Also, the POWER-breathe® device's effects on the strength of the diaphragm muscle and minimize muscle weakness and wasting in COPD patients.
Neuromuscular electrical stimulation (NMES) is commonly used in physical therapy to increase muscle strength and promote muscle hypertrophy. NMES applied to respiratory rehabilitation is called transcutaneous electrical diaphragmatic stimulation (TEDS).
sixty Patients will be assigned randomly into two equal groups with pre and post treatment protocol application.
Group A:
Thirty patients will be treated by power breathe along with their prescribed medication.
Group B:
Thirty patients will be treated by Transcutaneous electrical Diaphragmatic Stimulation (TEDS) along with their prescribed medication.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| INSPIRATORY MUSCLE TRAINING | Experimental | Power Breathe: (3times/week for 8 weeks) The patient should inhale and exhale through the mouthpiece 30 times maximum. The training load is adjustable and should be set at a level appropriate for the patient to effectively train the inspiratory muscles. (Lázaro et al., 2021) |

| TRANSCUTANEOUS ELECTRICAL DIAPHRAGMATIC STIMULATION | Active Comparator | Transcutaneous electrical Diaphragmatic Stimulation(TEDS): (3times/week for 8 weeks) During each session, rectangular electrodes were placed on the parasternal region beside the xiphoid process; the sixth and seventh intercostal spaces in line with the mid-axillary line. The electrical current is pulsed, biphasic and symmetric, with the following parameters: frequency of 30 Hertz; 0.4ms phase width, rise time of 0.7 seconds; respiratory rate of 14 rpm; intensity is the minimum necessary to obtain diaphragm muscle contraction. TEDS intensity was gradually increased until visible muscle contraction was observed. (Hsin et al., 2022) |

| TRANSCUTANEOUS ELECTRICAL DIAPHRAGMATIC STIMULATION | Device | Transcutaneous electrical diaphragmatic stimulation (TEDS) has been used to improve respiratory muscle strength in patients with respiratory muscle weakness. A previous study reported that patients with chronic obstructive pulmonary disease (COPD) showed increased lung volume and oxygen saturation after a single session of TEDS. (Hsin et al., 2022) |
