Effects of Inspiratory Muscle Training in Pulmonary Hypertensive Patient

Although the progressive nature of pulmonary hypertension (PH), including the impairment of respiratory muscle function, studies have demonstrated beneficial effects of physical exercise on the functional limitations caused by the disease in this population, being an important collaborator to the conventional drug therapy.Respiratory muscle training (RMT) improves functional capacity and quality of life (QoL) in patients.A randomized controlled trial was conducted to evaluate the effectiveness of this protocol on respiratory muscle strength and endurance, functional capacity. 18 subjects were allocated in 2 groups, group A was control group and group B was experimental group. Group A or Control group received deep breathing exercises. Group B received 30 minutes of IMT 6days weekly for 2 weeks by using a pressure threshold device. The purpose of this study was to investigate the effects of inspiratory muscle training (IMT) in PAH. To evaluate effectiveness of IMT mouth pressure device ,functional capacity using 6 minute walking test (6MWT)health assessment via SF 36 questionnaire were used before and after training protocol.

control groups received deep breathing exercise 6 days a week for two weeks. Deep breathing exercises includes diaphragmatic breathing and pursed lip breathing.

Treatment group received inspiratory muscle training 20 minutes 6 days a week for two weeks.IMT was done by using pressure threshold device.

The 6-min walk test (6 MWT) is a submaximal exercise test drive that includes measurement of distance walked throughout a period of 6 minutes. The 6-minute walk distance (6 MWD) stipulates a measure for collective global retort of multiple cardiopulmonary and musculoskeletal structures involved in workout.The 6 MWT provides information about functional capacity, response to rehabilitation and prognosis slanting a broad range of chronic cardiopulmonary situations. Main strengths of the 6 MWT curb from its simplicity in conception and performing, low cost, ease of consistency, and acceptance by test individuals, including those who are deconditioned, aged, or fragile.

SF-36 is a setting of universal, clear, and easily instructed quality-of-life methods. These measures hang on upon patient self-reporting and are now widely utilized by trained care groups and by Medicare for everyday observing and assessment of care findings in mature patient role
