Abstract
Background. Patients undergoing maintenance hemodialysis (HD) suffer from respiratory symptoms, uremic myopathy and protein catabolism leading to reduction of functional capacity and respiratory muscle strength. Objective. To determine the efficacy of intradialytic respiratory training using concurrent flow resistance (CFR) on respiratory muscle strength and functional capacity. Subjects and methods. Forty patients with end stage renal disease on hemodialysis for at least 4 months, with their age ranged from 30 – 40 of both sexes (20 men and 20 women) participated in this study at hemodialysis center of Fayoum University Hospital, Fayoum, Egypt. A Single- interventional study group designed. The study period was 12 weeks. Maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), selected pulmonary function test, Functional capacity and fatigue severity scale (FSS) were evaluated before and after the study. Results. There was significant improvement in MIP, MEP, FEV1%, FVC%, 6MWT and FSS by 61.37%, 63.01%, 58.26%, 55.12%, 36.48% and 22.35% respectively, while no significant difference was recorded regarding to FEV1/FVC% ratio. Conclusion. It can be concluded that respiratory training using concurrent flow resistance (CFR) device for 12 weeks was effective therapeutic technique to improve respiratory muscle strength and functional capacity in patients with end stage renal disease on hemodialysis.
