<br/><br/> Purpose: To study the effect of respiratory muscle training by using (The Breather) on ventilatory functions in women after mastectomy. Subjects: 40 women with unilateral post-mastectomy were randomly selected from Baheya Center with an age range from (40-50) years old. (Received radiotherapy /chemotherapy and physical therapy sessions), divided into 2 equal groups (each group=20). Methods: Group A received respiratory muscle training with the breather device with physical therapy rehabilitation and Group B received physical therapy rehabilitation only. Both groups received sessions twice weekly for 12 weeks. Equipment used for evaluation: ventilatory function measuring device (Spirometer) used to measure ventilatory function (FEV1, FVC, FEV1/FVC, MVV), measuring tape used to measure chest expansion, and Functional Assessment of Chronic Illness Therapy - Dyspnea-10 item (FACIT-Dyspnea) Questionnaire. Results: There was a significant increase in FVC, FEV1, FEV1/FVC, and MVV in groups A and B post-treatment compared with results of pre-treatment measures. The percent of change in FVC, FEV1, FEV1/FVC, and MVV in group A was 51.42, 89.73, 22.86, 129.6, and 2.78% while that in group B was 22.49, 43.06, 15.25, and 62.58% respectively. However, there was no significant difference in the chest expansion between groups. There was a significant decrease in FACIT-Dyspnea and FACIT-Functional limitation in groups A and B. The percent of change in FACIT-Dyspnea and FACIT-Functional limitation in group A was 61.08 and 68.01% respectively while that in group B was 43.24 and 51.76% respectively. Conclusion: Respiratory muscle training via (The Breather) helped the improvement of ventilatory function and dyspnea when combined with physical therapy rehabilitation after mastectomy.<br/>
