Effect of 4 weeks inspiratory muscle training on inspiratory muscle strength and quality of life in dialysis patients. A pilot study

ABSTRACT:Background: Dialysis is the most preferred way to treat chronic kidney disease (CKD). Thecommonest complication associated with dialysis is uremic myopathy. Inspiratory muscletraining (IMT) improves the strength of respiratory muscles.Methods: 11 patients with Stage 4 and 5 of chronic kidney disease with more than 3 months of dialysis underwent Inspiratory muscle training using self-made inspiratory trainer by taking pre and post intervention values of Maximum inspiratory pressure (MIP) and QOL.Result: Paired t test was used and the MIP and QOL values are statistically significant with a p-value of < 0.0001 and 0.0124 respectively.Conclusion: Inspiratory muscle strength and QOL is reduced in dialysis patients and a 4-week inspiratory muscle training using a self-made inspiratory muscle trainer is effective to reverse the adverse effects of dialysis.Keywords: Kidney disease, complications, respiratory muscles, maximum respiratory pressure, muscle weakness, exercise.
