Respiratory Biofeedback Added to Strengthening Training in Patients With Chronic Kidney Disease
Sponsor: Universidad de Granada
Summary
The goal of this clinical trial is to learn whether diaphragmatic biofeedback added to respiratory muscle training improves clinical and functional outcomes in adults with chronic kidney disease. It will also evaluate the feasibility and acceptability of this intervention. The main questions it aims to answer are: Is diaphragmatic biofeedback added to respiratory muscle training acceptable and well tolerated in patients with chronic kidney disease? Does this intervention reduce respiratory symptoms and complications in this population? Does diaphragmatic biofeedback added to respiratory muscle training improve cardiorespiratory capacity and quality of life? Researchers will evaluate diaphragmatic biofeedback combined with respiratory muscle training and a placebo intervention based on conscious breathing to assess its effects. Participants will: * Perform the assigned intervention three times per day for 6 weeks * Follow a structured respiratory muscle training program with diaphragmatic biofeedback * Be monitored for symptoms, respiratory complications, and perceived quality of life throughout the study

Diaphragmatic biofeedback combined with respiratory muscle training
This intervention is novel because it integrates diaphragmatic biofeedback into a structured respiratory muscle training program specifically designed for patients with chronic kidney disease, a population in which respiratory dysfunction is prevalent yet under-addressed. By providing real-time feedback on diaphragmatic activity, the intervention aims to enhance motor learning, improve activation of the diaphragm, and optimize training efficiency beyond conventional breathing or respiratory muscle training approaches.
PLACEBO INTERVENTION
The placebo intervention will consist of concious guided breathing sessions based on the participant's subjective respiratory sensations, without the use of objective physiological feedback or diaphragm-specific biofeedback. Participants will be instructed to follow standardized breathing guidance focused on perceived comfort and awareness, matching the intervention group in session frequency and duration.
