Objective: To compare the effectiveness of inspiratory muscle training (IMT) and incentive spirometer on ventilatory functions in post-menopausal asthmatic women. Participants and methods: A total of forty postmenopausal women suffering from asthma, their ages ranged from 50 to 60 years old, and their body mass index of the patient don't exceed 30kg/m2. They were recruited from patient chest clinic in Kasr -El- Ainy Teaching Hospital, Cairo University, Egypt.

They signed a consent form, confidentiality was assured. They assigned into two groups (A) who received inspiratory muscle training in the form of: Inspiratory threshold muscle trainer in addition to traditional chest physical therapy intervention (Deep breath, cough training) while patients in group (B): received traditional chest physical therapy intervention and incentive spirometer, three sessions per week for six weeks. Patients in both groups were assessed before treatment (pre-training) then after treatment (post-training) (after 6 weeks) to measure lung functions using electronic spirometer. The training program was carried in the duration from January 2019 to July 2019.

Inclusion Criteria:

• Forty postmenopausal women suffering from asthma
• Their ages were ranged from 50 to 60 years,
• their body mass index (BMI) don't exceed 30kg/m2.
• All participants were asthmatic patient
• clinically and medically stable cases

Exclusion Criteria:

• participant who had chest infection,
• malignant diseases,
• Patients with chest trauma.
