Physical rehabilitation of lung transplant candidates and recipients plays an important in optimizing physical function prior to transplant and facilitating recovery of function post-transplant. As medical and surgical interventions in lung transplantation have evolved over time, there has been a demographic shift of individuals undergoing lung transplantation including older individuals, those with multiple co-morbidites, and candidates with respiratory failure requiring bridging to transplantation. These changes have an impact on the rehabilitation needs of lung transplant candidates and recipients. This review provides a practical approach to rehabilitation based on research and clinical practice at our transplant centre. It focuses on functional assessment and exercise prescription during an uncomplicated and complicated clinical course in the pre-transplant, early and late post-transplant periods. The target audience includes clinicians involved in pre- and post-transplant patient care and rehabilitation researchers.

Background. The objectives of this position statement were to provide evidence-based and expert-informed recommendations for exercise training in adult and children solid organ transplant (SOT) candidates and recipients and on the outcomes relevant to exercise training and physical function that should be evaluated in SOT. Methods. We identified randomized controlled trials (RCTs) and systematic reviews of exercise interventions in adult and pediatric SOT candidates and recipients. When RCTs were not available, studies of any design were reviewed. The key recommendations were based on scientific evidence and expert-informed opinion. Results. We recommended that exercise training should be offered in the pre- and posttransplant phase for both adults and children. In adults, exercise training pretransplant was safe, but there was insufficient evidence to provide specific guidelines on the training characteristics. RCTs in adult SOT recipients demonstrated that exercise training improved exercise capacity, lower extremity muscle strength, and health-related quality of life. To obtain benefits, exercise training should be of moderate to vigorous-intensity level, 3–5 times a week for a minimum of 8 weeks. In pediatrics, there is an urgent need for high-quality multicenter clinical trials in the pre- and posttransplant phases. Due to limited evidence, specific recommendations regarding training characteristics could not be provided for pediatrics. Conclusions. The clinical relevance of this position statement is that it provides a key step toward raising awareness of the importance of exercise training in SOT patients among transplant professionals. It also identifies key areas for further research.

This prospective interventional study investigated the impact of a three-month, ambulatory HA or HB, semi-individualized, PT-prescribed exercise program following pediatric HTx or LTx. SMW distance, strength, and flexibility were assessed at start and completion of the program and one yr after enrollment. Subjects received either an HB or HA exercise program three times per week. The cohort demonstrated clinically and statistically significant improvements in SMW distances at three months (425.7 ± 109.4-500.6 ± 93.6 m, p < 0.001) and at one yr (528.5 ± 66.6 m, p = 0.001), although there was no difference between the two groups at any time. Similar improvements were also observed in strength and flexibility measures. Correlates with higher SMW distance at three months and one yr included older age, male gender, and underlying diagnosis other than CHD. Male gender and diagnosis other than CHD were associated with a slower improvement in the SMW distance. This is the first report of institutionally based, outpatient exercise rehabilitation in the recovery following pediatric thoracic transplantation. We found similar improvements to HB interventions up to one yr after surgery. Further study of the role of exercise rehabilitation and long-term fitness outcomes is needed.
