Home-based exercise program for liver transplant recipients

A Home-based Exercise and Physical Activity Intervention After Liver Transplantation: Impact of Exercise Intensity - a Monocenter Randomized Controlled Trial [PHOENIX-Liver]

Not applicable Interventional Universitaire Ziekenhuizen KU Leuven · NCT06302205

This study is testing whether different levels of exercise at home can help people who have recently had a liver transplant feel better and improve their health over six months.

What this trial studies

This study investigates the impact of different exercise intensities on the rehabilitation of patients who have recently undergone liver transplantation. Participants will be randomly assigned to one of three training groups (low, moderate, or moderate to high intensity) and will engage in a six-month home-based rehabilitation program supervised by a PHOENIX investigator. Assessments of physical fitness, cardiovascular health, liver function, and body composition will occur at baseline, three months, and six months, alongside monthly questionnaires to evaluate well-being and quality of life. The study aims to establish a feasible and effective exercise regimen to improve long-term outcomes for liver transplant recipients.

Who should consider this trial

Good fit: Ideal candidates are de novo adult liver transplant recipients who are two to three months post-transplant and have access to a home freezer.

Not a fit: Patients with severe comorbidities, ongoing malignancies, or those unable to participate in physical exercise due to medical contraindications may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could significantly enhance physical fitness and reduce cardiovascular risks in liver transplant recipients.

How similar studies have performed: Previous studies have shown positive outcomes with structured rehabilitation programs for transplant recipients, suggesting this approach may be effective.
