Respiratory, Limb Muscle Properties, and Physical Performance in Adult Lung Transplant Recipients
Who can join
Ages 18 and older · All sexes
Full eligibility criteria
Inclusion Criteria: * 18 years or older. * Hospitalized as potential candidates for single- or bilateral-lung transplant surgery. * Hemodynamically stable for out-of-bed mobilization Exclusion Criteria: * Baseline cognitive impairment * History of previous solid organ transplantation or thoracic surgery * Existing phrenic nerve lesion * Lower limb amputation or fracture * External fixators or open wounds of the lower extremities * Diagnosed neuromuscular disorder. * Morbid obesity (body mass index \>45 kg/m²). * Any other medical condition that, in the opinion of the investigators, would make participation unsuitable.
About the study
The goal of this observational study is to evaluate respiratory and limb muscle properties in adults awaiting lung transplantation and determine how these measures relate to physical performance, symptoms, and recovery after transplantation. Respiratory and limb muscle weakness may contribute to impaired mobility, frailty, and delayed postoperative recovery, but their specific role in lung transplant candidates is not well understood. Participants will undergo muscle ultrasound imaging at weekly basis, respiratory and limb strength testing, physical performance assessments, and symptom questionnaires once before and after transplantation. Researchers will also collect information from medical records regarding intensive care unit stay, hospital length of stay, rehabilitation participation, and postoperative recovery outcomes.
