COPD (Chronic Obstructive Pulmonary Disease)
Conditions
Brief summary
The goal of this Randomize control trail is to determine the effect of Digital High-Intensity Respiratory Muscle Training on ventilatory Function and Functional Capacity in Patients with COPD It will also learn about the safety and tolerability of this digital training program. 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
This single-blinded randomized controlled trial is to determine effect of Digital High-intensity Respiratory Muscle Training delivered through the Sonmol electronic respiratory muscle trainer on ventilatory function and functional capacity in patients with chronic obstructive pulmonary diseases (COPD) 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.
Interventions
DEVICEDigital 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.
OTHERconventional 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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ventilatory function measures (FVC, FEV1, and FEV1/FVC) | twice, first before beginning treatment from day 1 of treatment second after complete treatment after 2 months ,Assessment will be for 5 minutes for ventilatory function | will be assessed by using Spirometry (smartSOFTmee version 2.14.21) FVC (Forced Vital Capacity): The maximum volume of air that a person can forcibly exhale after taking a full, deep inhalation. FEV₁ (Forced Expiratory Volume in 1 second): The volume of air exhaled during the first second of the forced expiratory maneuver. FEV₁/FVC ratio: The percentage of the total forced vital capacity exhaled in the first second, used to assess the presence of airflow obstruction. After preparing the device and the patient and delivering instructions, each patient will assume the sitting position with a nose clip on the nose, they will asked to take a deep breath quickly, with a hold of more than one second at TLC, next, firmly seal the mouthpiece with the lips, then execute the FVC technique. Lastly, forcefully exhale for as long as he/she can and as quickly as feasible while loudly asking for more, more, more. This process should last for at least six seconds |
| Functional capacity by 6MWT | twice ,first before beginning treatment from day 1 of treatment ,second after complete treatment after 2 month Assessment will be for 6 minute | The 6MWT will be used to measure functional exercise capacity. The investigator measures blood pressure, heart rate, and oxygen saturation. The Patient wears clothing and footwear that are safe for testing. The walking surface will be hard and flat. Often, two cones are set up about 100 feet (30 meters) and the patient will walk back and forth between them for six minutes. At the end of the test, the investigator calculates the distance the patient walked in 6 minutes, |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Respiratory muscle strength (MIP and MEP). | twice, first before beginning treatment from day 1 of treatment ,second after complete treatment after 2 month Assessment will be for 3 minute | it will be used for assessment of respiratory muscle strength. Manometers are pressure reading devices used to measure positive and negative pressures objectively . One manometer developed specifically for maximal expiratory (MEP), and inspiratory (MIP) respiratory pressure testing is the Sonmol Digital Manometer Electric Version. |
| Patient-reported outcomes by CAT score | twice ,first before beginning treatment from day 1 of treatment ,second after complete treatment after 2 month Assessment will be for 4 minute | the CAT is a questionnaire that can assess the patient-reported outcomes and the effect of symptoms on COPD patients' lives. The CAT asks eight questions, prompting to assign a score ranging from 0 to 5 for each area A score of 0 means there's no impairment in that area. A score of 5 means severe impairment. The overall score will range from 0 to 40 |
