About

Heart failure is a complex clinical syndrome manifesting as inability to supply adequate blood flow throughout the body due to any structural or functional cardiac abnormality. The most common complaints are exercise intolerance, balance, dyspnea, and fatigue in patients with heart failure. It is clearly stated that pulmonary muscle weakness is prevalent and contributes to exercise intolerance in patients with heart failure. Purpose of the study was to evaluate the efficacy of inspiratory muscle traning on pulmonary muscle strength, pulmonary function test, functional capacity and quality of life. The tools used were 6-minute walk test, spirometry, IMT threshold device for IMT strength, and Quality of life. Study was conducted in 20 patients in single group and pre and post values were evaluated. The significance this study bears was that it helped defining for us that to how much extent we can improve the physical and pulmonary functional capacity using inspiratory muscle training. Data were analysed using spss 22.0.mean and standard deviation were calculated. Appropirate the stasitical test were used after checking normailty of data. Parametric test were used for data analysis using SPSS 22

Description:

Patients were assigned to inspiratory muscle training (IMT) for 6 weeks. During training, patients were instructed to maintain diaphragmatic breathing, and try to maintain 10-15 breaths, and rested 5-10 between breaths. As soon as the patients managed; they were encouraged to maintain 25-30 breaths at each workload. All patients wore nose-clip during training. The inspiratory load was set at 40% of maximal inspiratory pressure. The training session was supervised at the hospital.

Other: Inspiratory Muscle training
