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)?

Conditions

COPD (Chronic Obstructive Pulmonary Disease)

Outcome Measures

Primary Outcomes (2)

• Ventilatory function measures (FVC, FEV1, and FEV1/FVC)

  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

  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

• Functional capacity by 6MWT

  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,

  twice ,first before beginning treatment from day 1 of treatment ,second after complete treatment after 2 month Assessment will be for 6 minute

Secondary Outcomes (2)

• 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

• 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

Study Arms (2)

Group A (study group)

EXPERIMENTAL

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.

Device: Digital Sonmol Respiratory Muscle Trainer; Other: conventional respiratory rehabilitation

Group B (control group)

EXPERIMENTAL

30 patient who will receive the conventional pulmonary rehabilitation program for 25 to 30 minutes for each session, 3 sessions / week, for 8 weeks.

Other: conventional respiratory rehabilitation

Interventions

Digital Sonmol Respiratory Muscle Trainer DEVICE

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.

Group A (study group)

conventional respiratory rehabilitation OTHER

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 A (study group); Group B (control group)
