Treinamento muscular inspiratório em indivíduos com doença renal crônica submetidos à hemodiálise

Abstract

The respiratory muscles is a muscle group that may change, such as loss of strength and endurance in patients with chronic kidney disease (CKD), characteristic of the uremic syndrome. The inspiratory muscle training (IMT) can reduce symptoms such as dyspnea and inspiratory muscle fatigue. The objective of the study was to evaluate effects pre and post TMI in individuals with CKD undergoing hemodialysis (HD) on respiratory muscle strength, pulmonary function, sub - maximal functional capacity and quality of life. Randomized, multi - blind, composed of 22 individuals assessed at baseline and immediately after the protocol. The sample was divided into two groups, charged TMI (n = 11) and IMT-S uncharged (n = 11). Training was performed during HD sessions for 12 weeks. No statistically significant difference at baseline and following 12 weeks between groups IMT- S and IMT as the assessed traits were observed. When comparing the differences of the value obtained for MIP and MEP following 12 weeks compared to baseline was observed that both the gain was significantly higher in group IMT-S than in the TMI group, 13.3% ( 8.5 % - 20.6 % ) vs 5.0% ( -3.7 % - 10.0% ), p = 0.041 and 11.5 % (8.5 % - 15.3%) vs 5.2% (1.0% - 10.6%), p = 0.018, respectively. The IMT-S proved so effective in improving the MIP as the technique that uses load, and this intervention can be put into practice to gain muscle strength in chronic renal disease
