Abstract

Background: Mitral valve replacement was done in 80% of cases with valvular heart diseases (Gummer et al., 2008). Despite advances in reparative techniques, valve replacement surgery is considered as treatment option to restore proper heart function in people with mitral valve disease (Alain Pratt et al., 2001). Mitral valve replacement were accomplished in 1960 by harken and Starr. Diseases of the heart valves constitute a major cause of cardiovascular morbidity and mortality worldwide with an enormous burden on healthcare resources.

Specific Objective: To compare the effect of Threshold inspiratory muscle training device along with Conventional physiotherapy on the endurance capacity and quality of life in mitral valve replacement.

Design: Pre-test and Post-test experimental study design

Study Settings: Department of Physiotherapy, Narayana hospital, Nellore.

Intervention: 30 patients were selected and divided in to two groups Group –A was given with conventional physiotherapy and Group –B  was given with Threshold inspiratory muscle training .and total duration was 8 weeks and  3 session per week and 30 -40 min per session.

Out cum measures: six minute walk test, short form – 36 questionnaire

Result & Conclusion: The purpose of the study is to find out the effect of analyze the efficacy of Threshold Inspiratory Muscle Training Device Compare with Conventional Breathing Exercises on Improving endurance capacity and Quality of Life in Mitral Valve Replacement. Based on this statistical analysis the Group B participants show a marked improvement in the six minute walk test and the quality of life questionnaire when compared to Group A participants. Therefore, this study strongly suggests that inspiratory muscle training when added to conventional physiotherapy program proved to be significantly effective in improving endurance capacity and quality of life as compared to conventional physiotherapy alone in mitral valve replacement

Keywords: MVR,, Threshhold inspiratory muscle training.
