Can a new breathing workout help lung transplant patients breathe easier?
NCT ID NCT06963190
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study compares two types of breathing muscle training in people who have had a lung transplant. One group does standard constant-resistance exercises, while the other adds short bursts of harder effort. The goal is to see which method better improves breathing strength and daily function over the first six months after transplant. About 42 adults will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- inspiratory muscle training (breathing exercises) using either constant resistance or intermittent variable resistance
- What this could lead to
- If successful, this could point to a better breathing exercise program for lung transplant patients, helping them recover more strength and function.
- What could go wrong
- This is a small, early-stage trial with only 42 participants, so results may not apply to all patients. The training is safe but may not show a clear benefit over standard care.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult patient (≥18 years) who has undergone lung transplantation (single-lung or double-lung) at our center. * Alert and cooperative (Glasgow Coma Scale \>13 points). * Hemodynamically stable (blood pressure between 90/60 and 165/90 mmHg; heart rate between 60 and 130 beats per minute). * No disabling dyspnea at rest (maintained at mild levels according to the Borg scale or NYHA class I-II), even if requiring supplemental oxygen with a saturation \>89%. * No limiting chest pain interfering with respiratory therapy. Exclusion Criteria: * Patients unable to cooperate with treatment due to lack of necessary instrumental cognitive skills. * Perceived non-adherence to pharmacological and non-pharmacological treatment by healthcare personnel. * Need for continuous non-invasive mechanical ventilation, high-flow oxygen therapy, or Venturi mask. * Patients with significant neurological disorders, severe polyneuropathies, or stroke (CVA). * Presence of tracheostomy, active hemoptysis, bronchial suture dehiscence. * Significant air leak with clinical repercussions. * Any clinical condition that, in the investigator's judgment, poses a risk to the patient.
