This randomized controlled study aims to evaluate the effectiveness of a digital rehabilitation exercise platform in patients undergoing living donor liver transplantation. A total of 36 adult patients who require ongoing rehabilitation after living donor liver transplantation will be recruited and randomly assigned in a 1:1 ratio to either an intervention group or a control group. The intervention group will receive a personalized exercise program delivered through a digital rehabilitation platform in addition to standard exercise education, whereas the control group will receive standard exercise education only. Physical function, body composition, quality of life, and physical activity will be assessed before surgery, at discharge, at 1 month after discharge, and at 3 months after discharge to determine whether the digital rehabilitation platform improves recovery-related outcomes during the post-transplant period.
