Effects of Perioperative Rehabilitation on Physical Function in Kidney Transplant Recipients

Le résumé fourni par la source

ABSTRACT Background Sarcopenia and frailty are common among kidney transplant candidates and often persist even after transplantation. Exercise therapy initiated during the perioperative period may improve physical function, but its benefits remain underexplored. Methods We conducted a single‐center prospective observational study evaluating a structured rehabilitation protocol in kidney transplant recipients. Patients received supervised exercise therapy starting from postoperative day (POD) 2, followed by resistance training and aerobic exercise during hospitalization. Upon discharge, participants were instructed to continue monthly supervised training sessions. Outcomes including skeletal muscle index (SMI), handgrip strength, gait speed, anaerobic threshold VO 2 , and peak VO 2 were assessed before transplant and at 1 year post‐transplant. Improvement rates were compared between patients who received rehabilitation and those who did not, and further among those who continued post‐discharge training. Results Patients in the rehabilitation group showed significantly greater improvements in grip strength, gait speed, and VO 2 parameters compared to the control group ( p < 0.05). Among the rehabilitation group, those who continued training post‐discharge for ≥6 months exhibited the most pronounced improvements. No adverse effects on renal function were observed. Conclusions Early and sustained rehabilitation is effective and safe for improving physical function in kidney transplant recipients. Incorporating structured exercise therapy into routine perioperative and post‐discharge care may enhance recovery and clinical outcomes.
