Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older who are hospitalized as potential single- or bilateral-lung transplant candidates and are hemodynamically stable for out-of-bed mobilization.
✕Probably not a fit
Patients with cognitive impairment, prior solid organ or thoracic surgery, neuromuscular disorders, or other exclusions may not benefit from the study.

What this trial studies
This observational study will characterize respiratory and limb muscle properties in adults waiting for lung transplantation and after transplant. Researchers will perform weekly ultrasound imaging of selected muscles, plus strength tests, physical performance measures, and symptom questionnaires before and after transplantation. Medical records will be reviewed for ICU stay, hospital stay, rehabilitation participation, and recovery outcomes to explore associations with muscle characteristics. The goal is to see whether muscle structure and strength help explain differences in mobility, frailty, symptoms, and recovery after surgery.
Why it matters
Potential benefit: If successful, findings could help identify muscle factors that influence recovery and guide pre- and post-transplant rehabilitation strategies.
How similar studies have gone: Previous work using ultrasound to assess muscles in critically ill populations has linked muscle health to recovery outcomes, supporting the relevance of this approach in transplant patients.
