Brief summary

The goal of this randomized controlled trial is to compare the influences of a traditional pulmonary rehabilitation program versus a combined program including the Lung Boost device on pulmonary function and quality of life in women with compromised respiratory function. The study will conducted on 50 female participants aged 50-60 years, including post-unilateral mastectomy and postmenopausal cases. Participants will be randomly assigned into two (2) groups: * Traditional Group (n=25), will receive conventional breathing exercises and the Lung Boost Group (n=25), will receive the same exercises plus Lung Boost respiratory muscle training. * Intervention will last 6 weeks 1 session/ day. Pulmonary function parameters (FVC, FEV1, FEV1/FVC, MVV), and quality of life will be assessed pre- and post-treatment. The main question it aims to answer "Is Lung Boost device has a positive effect on Pulmonary Function in Post-mastectomy Postmenopausal women?" Researchers will compare conventional breathing exercises to Lung Boost respiratory muscle training. to see if Lung Boost device can improve pulmonary function, and quality of life in Post-mastectomy Postmenopausal women.

Detailed description

This randomized controlled trial aims to evaluate and compare the effects of a conventional pulmonary rehabilitation program versus a combined intervention incorporating the Lung Boost device on pulmonary function and quality of life among women with impaired respiratory function. The study will include fifty (50) female participants aged between 50 and 60 years who have undergone unilateral mastectomy and are in the postmenopausal stage. Participants will be randomly allocated into two equal groups. The Traditional Group (n=25) will receive standard pulmonary rehabilitation consisting of conventional breathing exercises, while the Lung Boost Group (n=25) will receive the same regimen supplemented with respiratory muscle training using the Lung Boost device. The intervention period will extend over six weeks, with sessions conducted once daily. Outcomes will be assessed both before and after the intervention. Pulmonary function will be evaluated through spirometric measurements, including forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), the FEV₁/FVC ratio, and maximum voluntary ventilation (MVV). In addition, quality of life will be assessed using a validated questionnaire appropriate for the target population. The study seeks to determine whether the inclusion of the Lung Boost device within a structured pulmonary rehabilitation program yields significant improvements in pulmonary function and overall quality of life in postmastectomy, postmenopausal women with compromised respiratory performance, compared with conventional breathing exercises alone.

Interventions

BEHAVIORALBreathing Exercises

Participants will perform a standardized set of breathing and relaxation exercises consisting of: Diaphragmatic breathing (approximately 15 minutes) Pursed-lip breathing (approximately 10 minutes) Relaxation techniques (approximately 5 minutes) Frequency \& Duration: One session daily, 5 sessions per week, for 6 consecutive weeks. Session Length: 30 minutes per session. Provider/Setting: Initial instruction and supervision by a licensed physiotherapist; exercises thereafter performed at home with adherence logs. Safety Monitoring: Participants will be advised to stop if dizziness, chest pain, or unusual shortness of breath occurs, and will report adverse events weekly.

DEVICELung Boost device in addition to Behavioral: Breathing exercises

Intervention Type 1: Device (Respiratory Muscle Training) Intervention Name 1: Lung Boost respiratory muscle trainer Intervention Description 1: Inspiratory/expiratory muscle training using the Lung Boost device. Training parameters: resistance at 30% of maximal inspiratory pressure progressing up to 60% over 6 weeks\]. Frequency \& Duration (Device): 15 minutes per session, once daily, 5 days per week, for 6 weeks. Intervention Type 2: Behavioral (Breathing exercises) Intervention Name 2: Diaphragmatic breathing, Pursed-lip breathing, Relaxation techniques Intervention Description 2: Same standardized breathing and relaxation program as the control group (15 + 10 + 5 minutes). Frequency \& Duration (Exercises): 5 sessions per week, for 6 weeks. Session Length (Exercises): 30 minutes per session. Total Daily Time Commitment: Approximately 45 minutes (15 minutes device + 30 minutes breathing exercises).

Design outcomes

Primary

MeasureTime frameDescription
Forced Vital Capacity (FVC, L) Forced Expiratory Volume in one second (FEV₁, L) FEV₁/FVC ratio (%) Maximum Voluntary Ventilation (MVV, L/min)Measurements will be taken at baseline and after 6 weeks of intervention.These variables are used to quantify respiratory muscle performance and ventilatory efficiency.

Secondary

MeasureTime frameDescription
Chest Expansion (cm)Measurements will be taken at baseline and after 6 weeks of intervention.Assessed using a measuring tape at the level of the xiphoid process to determine thoracic mobility during maximal inspiration and expiration.
Functional Assessment of Chronic Illness Therapy-Dyspnea (FACIT-Dyspnea) and FACIT-Functional Limitation scalesApplied at baseline and after eight weeks of intervention.Quality of Life sacles using to assess the impact of respiratory limitations on daily activities and overall well-being.
Body mass index (BMI, kg/m^2)Applied at baseline and after eight weeks of intervention.Body Mass Index (BMI, kg/m\^2) is a screening tool that estimates the total body fat based on height and weight. It is calculated by dividing weight in kilograms by the square of height in meters (BMI = fraction {kg}{m\^2})
