Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Inspiratory muscle training (IMT) has been extensively studied in a variety of non-LTX populations and research has shown that IMT improves exercise capacity, diaphragmatic thickness, and reduced dyspnea during activities of daily living and improved quality of life in patients with advanced lung disease.
The aim of this randomized controlled study is to investigate the benefits of providing inspiratory muscle training via use of an inspiratory muscle trainer device in addition to standard physical therapy in the acute phase of rehabilitation following LTX. Patients targeted for enrollment will be those with any type of advanced lung disease requiring LTX with the objective of demonstrating improvements in respiratory muscle recovery, perceived dyspnea, severity of fatigue, and overall functional status following the transplant procedure.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Inspiratory Muscle training- Intervention group
Along with standard post-transplant physical therapy, the intervention group will begin daily respiratory exercise training utilizing the IMT trainer device (POWERbreathe Medic Plus®) with weekly incremental increases in respiratory load. Patients will be asked to use the IMT device twice per day, 7 days per week, for 8 weeks.
IMT- Intervention group
The resistive load will be readjusted weekly to reach 50% of maximal inspiratory pressure (MIP).
Inspiratory Muscle training - Placebo group
Along with standard post-transplant physical therapy, the placebo group will begin daily respiratory exercise training utilizing the IMT trainer device (POWERbreathe Medic Plus®) with no increase of respiratory load. Patients will be asked to use the IMT device twice per day, 7 days per week, for 8 weeks.
IMT- Placebo group
The inspiratory resistive load will be adjusted to the minimum value of the device (9 cm H2O) during all inspiratory muscle training sessions.
Usual care group
Patients will only participate in standard post-transplant physical therapy.
