Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main questions it aims to answer are: Does digital high-intensity respiratory muscle training improve inspiratory and expiratory muscle strength (MIP and MEP)? ,Does it improve functional exercise capacity (6-minute walk distance) and lung function (FEV₁, FVC, FEV₁/FVC)?

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
It articulates the clinical rationale by explaining how airflow limitation is caused by COPD and chest hyperinflation, or dysfunction of respiratory muscles, and describes why specific, intense exercise training of muscles of inspiration or expiration may correct or prevent these conditions.
This trial within current evidence supporting respiratory-muscle training and highlights the potential advantages of digital delivery-real-time feedback, adjustable resistance, gamification, and remote monitoring-to boost adherence and training specificity in a rehabilitation context.
The study compares digital high-intensity respiratory muscle training plus conventional pulmonary rehabilitation to conventional pulmonary rehabilitation alone to see if the digital training provides additional benefits.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A (study group)
30 patient who will receive high-intensity respiratory training with the digital Sonmol Respiratory Muscle Trainer for 15 to 20 Minutes, in addition to a conventional pulmonary rehabilitation program for 25 to 30 Minutes, with a total duration of 50 to 60 minutes for each session.
, 3 sessions/week, for 8 weeks.
Digital Sonmol Respiratory Muscle Trainer
The patient will be asked to inhale deeply and forcefully for approximately two to three seconds and have a pause of slightly under a second. Then exhale out of the device and rest for 30 to 60 seconds and will be done for 2 sets of ten breaths, two times per day, for eight weeks The resistance will increase about 10 % to 15 % every week according to patient status in addition to a conventional respiratory rehabilitation program for 25 to 30 Minutes, with a total duration of 50 to 60 minutes for each session.
conventional respiratory rehabilitation
The patients will receive conventional respiratory Rehabilitation in the form of Diaphragmatic breathing exercise for 5 to 10 minutes and Localized Breathing for lower, middle, and upper segments for 10 to 15 minutes, total session time 25 to 30 minutes for two to four sessions daily for 3 days/ week for 8 weeks
Group B (control group)
30 patient who will receive the conventional pulmonary rehabilitation program for 25 to 30 minutes for each session, 3 sessions / week, for 8 weeks.
conventional respiratory rehabilitation
The patients will receive conventional respiratory Rehabilitation in the form of Diaphragmatic breathing exercise for 5 to 10 minutes and Localized Breathing for lower, middle, and upper segments for 10 to 15 minutes, total session time 25 to 30 minutes for two to four sessions daily for 3 days/ week for 8 weeks
