Summary

Chronic obstructive pulmonary disease (COPD) is characterized by persistent respiratory symptoms and airflow limitation, often exacerbated by postural abnormalities such as forward head posture (FHP). FHP can lead to significant alterations in breathing patterns, reducing the efficiency of respiratory muscles and impairing lung function. Patients with COPD and FHP frequently exhibit muscular imbalances, where overactive accessory muscles compensate for weakened primary respiratory muscles Resistive Inspiratory Muscle Training strengthens inhalation muscles using resistance devices to enhance respiratory function in COPD patients. Resistive Expiratory Muscle Training focuses on strengthening exhalation muscles through resistance during exhalation, improving breathing efficiency. Posture Correction Exercises address forward head posture by stretching tight muscles and strengthening weak ones to optimize breathing mechanics. Combined Resistive Inspiratory and Expiratory Muscle Training integrates both inspiratory and expiratory muscle training, using resistance for both inhalation and exhalation, to maximize respiratory efficiency and overall lung function in COPD patients. The objective of the study is to determine the effects of combined exercise and resistive respiratory muscles training on dyspnea, chest expansion, craniovertebral angle and pulmonary function test, in COPD patients with forward head posture.

Patients of COPD with forward head posture will be recruited by convenient sampling technique using seal opaque method. 72 patients will be equally divided into three groups with 24 patients each. Posture correction exercises will be added as baseline treatment for all three groups session. GROUP A will be treated with resistive inspiratory muscles training (RIMT). GROUP B will be treated with resistive expiratory muscles training (REMT). GROUP C will be treated with combined resistive inspiratory and expiratory muscles technique (RIMT+REMT).treatment session will be of 8 weeks and will include three reading (pre, post treatment and one follow-up). Outcomes measurement will include; dyspnea by dyspnea 12 questionnaires, chest expansion by measuring tape, craniovertebral angle by radiograph and pulmonary function test by spirometer. Data will be analyzed by SPSS software version 21.

Interventions

DEVICE

Resistive inspiratory muscles training

Resistive Inspiratory Muscle Training (IMT) will be implemented using a threshold inspiratory muscle trainer, which requires patients to inhale through a one-way valve that provides adjustable resistance. The training sessions will begin with patients sitting comfortably in an upright position to optimize lung function. They will be instructed to take a deep breath, ensuring their diaphragm engages fully, and then inhale through the device, which will resist airflow, thereby increasing the workload on the inspiratory muscles. Initially, the resistance will be set at a level that is challenging yet achievable, with the aim to gradually increase resistance as the patient's strength and endurance improve. Each session will last 30 minutes, consisting of intervals of resisted inhalation followed by brief rest periods. Patients will perform 3 sets of 10 breaths with appropriate breaks in between. The training will be conducted 3 times per week,

DEVICE

Resistive expiratory muscles training:

Resistive Expiratory Muscle Training (EMT) will be employed to enhance the strength and endurance of the expiratory muscles in COPD patients. This training will utilize a threshold expiratory muscle trainer, designed to provide resistance during exhalation, thereby engaging the abdominal and intercostal muscles effectively. Patients will begin each session in a comfortable, upright position to optimize lung function. They will be instructed to take a deep inhalation to fully expand their lungs, and then exhale forcefully through the device against the resistance. The resistance level will be adjustable and initially set to a manageable level, with plans to gradually increase it as the patient's strength improves. Each training session will last 30 minutes, consisting of intervals of resisted exhalation followed by brief recovery periods. Patients will perform 3 sets of 10 breaths, with appropriate breaks in between. it will be performed 3 times per week

DEVICE

Combined resistive inspiratory and expiratory muscles training

Resistive Inspiratory and Expiratory Muscle Training will be implemented concurrently as a comprehensive approach to enhance the strength and endurance of both inspiratory and expiratory muscles in COPD patients. During each session, patients will utilize a threshold inspiratory muscle trainer for inhalation while simultaneously using a threshold expiratory muscle trainer for exhalation. Each training session will last 20-30 minutes, beginning with patients taking a deep breath to fully engage their diaphragm before inhaling through the inspiratory trainer and exhaling forcefully against the resistance of the expiratory trainer. Patients will perform 3 sets of 10 breaths, with appropriate breaks in between to prevent fatigue and ensure effective training. This resistive EMT protocol will be conducted 3 times per week
