Lung Boost Therapy on Post-mastectomy Postmenopausal

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.
