Clinical Trial Summary

The goal of this study is 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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Inspiratory muscle strength	A mouth pressure device will be used to evaluate IMS.	First day
Secondary	Functional exercise capacity	Functional exercise capacity will be evaluated with 6 minutes working test. Test will be performed in an enclosed 30-m corridor. The patients walk as fast as they could within 6 min.	First day
Secondary	Peripheral muscle strength	A hand-held dynamometer will be used to measure peripheral muscle strength. The measurements will be repeated three times, and the highest value will be used for comparison.	First day
Secondary	Expiratory muscle strength	A mouth pressure device will be used to evaluate EMS.	First day
Secondary	Pulmonary functions FEV1	Spirometry will be used to assess pulmonary function.	First day
Secondary	Pulmonary functions FVC	Spirometry will be used to assess pulmonary function.	First day
Secondary	Pulmonary functions FEV1/FVC	Spirometry will be used to assess pulmonary function.	First day
Secondary	Pulmonary functions PEF	Spirometry will be used to assess pulmonary function.	First day
Secondary	Pulmonary functions FEF25-75%	Spirometry will be used to assess pulmonary function.	First day
Secondary	Dyspnoea	Dyspnoea will be measured using the Modified Medical Research Council (MMRC) dyspnoea scale. Levels of dyspnea are graded 0-4.	First day
Secondary	Fatigue	Fatigue will be assessed using the Fatigue Severity Scale (FSS). The total score ranges from 0 to 7.	First day
Secondary	Quality of life assessment	The Short Form 36 (SF-36) questionnaire will be used to assess QoL and includes both physical and mental components. The scores range from 0 to 100.	First day
Secondary	Physical activity	Physical activity will be assesed using the International Physical Activity Questionnaire (IPAQ) short form, which includes questions on sitting duration, walking activity, and moderate and vigorous activities.The IPAQ is categorized as inactive (<600 MET-min/week), minimally active (600-3000 MET-min/week), and sufficiently active (>3000 MET-min/week) based on total scores.	First day
Secondary	Balance	Balance will be evaluated using the Berg Balance Scale (BBS). The scale includes 14 items scoring 0 to 4. Higher scores indicate better balance.	First day
