Comparing breathing muscle training methods for adults undergoing hematopoietic stem cell transplant

Official title: Effects of Different Inspiratory Muscle Training Protocols in Hematopoietic Stem Cell Transplant Recipients

Run by Istinye University · NCT07061444 · Data updated 2026-11-12

This trial tests whether different inspiratory muscle training programs help improve breathing strength, reduce breathlessness and fatigue, and boost exercise ability in adults having a hematopoietic stem cell transplant.

Is this trial a fit for you?

Likely a good fit

Adults 18–65 who are planned for hematopoietic stem cell transplantation, are able to walk and follow instructions, are clinically stable, and have no orthopedic, neurological, cardiac, or chronic pulmonary conditions are ideal candidates.

Probably not a fit

Patients with active pulmonary disease (like asthma or COPD), acute infections, cognitive impairment, or medical contraindications to exercise are unlikely to benefit or be eligible.

What this trial studies

Patients undergoing hematopoietic stem cell transplantation often develop respiratory weakness, fatigue and reduced quality of life. This study compares three inspiratory muscle training protocols—standard IMT, functional IMT, and a sham IMT—delivered during the transplantation process to see which approach produces the best improvements. Eligible adults aged 18–65 without major orthopedic, neurological, cardiac, or chronic pulmonary comorbidities will be assigned to one of the training protocols while receiving standard medical care. Outcomes include respiratory muscle strength and endurance, dyspnoea, maximal exercise capacity, diaphragmatic and pulmonary function, peripheral muscle strength, fatigue, quality of life, and blood markers of oxidative stress and inflammation.

Why it matters

Potential benefit: If successful, the preferred IMT protocol could strengthen breathing muscles, lessen breathlessness and fatigue, and speed functional recovery after transplant.

How similar studies have gone: Inspiratory muscle training has shown benefit in populations such as COPD and perioperative patients, but evidence specifically in HSCT recipients is limited and this application is relatively novel.
