Peripheral and respiratory muscle weakness has been reported in patients with chronic kidney disease (CKD). Management of respiratory muscle weakness is crucial, as reduced functional performance is related to respiratory muscle weakness.
Different IMT function protocols with 30-70% of the maximal inspiratory pressure (MIP) have been found to improve these in patients with CKD. The most efficient IMT intensity for patients with CKD is unknown. Therefore, this study aims to investigate the effects of different IMT protocols on respiratory muscle strength, functional exercise capacity, quadriceps femoris muscle strength (QMS), handgrip muscle strength (HGS), QoL, respiratory function, dyspnoea, fatigue, balance, and PA levels in patients with CKD that were not on dialysis.
