Does Inspiratory Muscle Trainer Have an Effect on Diaphragmatic Excursion in Hemodialytic Patients?

Abstract

Background: Hemodialysis patients suffer from severe muscular weakness and one of the most important muscle is the diaphragmmain muscle of respiration -that was experienced by dyspnea and decreased functional capacity due to a unique form of protein and energy malnutrition .Purpose: to determine the response of diaphragmatic excursion to inspiratory muscle trainer prior hemodialysis session. Methods: Thirty patients of both sexes (10 men and 20 women) were included in this study with mean age(± SD) was 35.47 (± 6.51). They were chosen from El Sahel Teaching Hospital, Nephrology department, dialysis unit, and undergoing dialysis from at least 2-3 years.Ultrasonography (U.S) was used to assess diaphragmatic excursion (D.E) during deep breathing maneuver before and at the end of the training program. All patients received the inspiratory muscle training for 12 weeks, 3 times/week. Results: The results of this study showed statistical significant difference between pre and post-training in diaphragmatic excursion (p ˂0.001) with a percentage of improvement 65.74%. The percentage of improvement in men was 65.29% corresponds that in women was 66.08% compared to the predata status. Conclusion: Inspiratory muscle training by inspiratory muscle trainer device for 12 weeks in hemodialysis patients had significantly improved the diaphragmatic excursion (DE) that ensures the improvement in their mechanics of breathing and sense of dyspnea.
