Effect of Inspiratory Muscle Training on Physiological Function and Clinical Outcomes After Lung Transplant
December 8, 2023 updated by: Bryan Taylor, Mayo Clinic
Effect of Inspiratory Muscle Training on Physiological Function and Clinical Outcomes After Lung Transplant: A Randomized Controlled Trial
The purpose of this research is to study the effect of training the inspiratory muscles (i.e. the muscle that allow you to breath-in) on exercise capacity, quality of life, and short-term clinical outcomes in patients post lung transplant.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: 12-weeks pulmonary rehabilitation training plus inspiratory muscle training
To assess maximum inspiratory pressure, you will be asked to breathe through a device called POWERBreathe Plus®.
This device is commercially available and will be provided to you by the study.
You will be asked to use this device twice per day, 5 days per week, for 12 weeks.
Each session will require you to breathe into the device 30 times.
You can use the device at home.
|
Commercially available pressure-threshold device
Pulmonary function, lung diffusing capacity for carbon monoxide, inspiratory muscle strength, and diaphragm dimensions will be assessed in each patient.
Each patient will also undergo a cardiopulmonary exercise test (CPET), 6 minute walk test, and an inspiratory muscle endurance test
|
Placebo Comparator: 12-weeks pulmonary rehabilitation plus placebo (inactive) inspiratory muscle
To assess maximum inspiratory pressure with placebo, you will be asked to breathe through a device called POWERBreathe Plus®.
This device is commercially available and will be provided to you by the study.
You will be asked to use this device twice per day, 5 days per week, for 12 weeks.
Each session will require you to breathe into the device 30 times.
You can use the device at home.
The resistance will be set to about 5% throughout the study.
