Long-Term Declines in Physical Fitness and Physical Activity for Individuals With Post-Liver Transplantation Compared to Healthy Controls.

Functional changes are essential determinants of mortality and morbidity in individuals with chronic liver disease. However, there is limited information about whether these changes persist long-term after liver transplantation (LT). We aimed to compare physical fitness, physical activity, balance, kinesiophobia, and fatigue between patients with LT and healthy controls. All participants underwent evaluation with the Senior Fitness Test (SFT) for exercise capacity and physical fitness, the International Physical Activity Questionnaire (IPAQ) for physical activity, the Timed Up-and-Go Test (TUG) and the Berg Balance Scale (BBS) for balance, the Tampa Scale for Kinesiophobia (TSK) for kinesiophobia, and the Fatigue Severity Scale (FSS) and Fatigue Impact Scale (FIS) for fatigue. We studied 16 persons with LT ( age = 40.56, = 15.73 years; time since LT = 66.81, = 72.05 months) and 16 control participants ( age = 39.87, = 13.98 years). Compared to controls, participants with LT showed significantly poorer performance on the SFT components assessing upper and lower body strength, aerobic endurance, agility, and dynamic balance ( < .001 for all), significantly lower IPAQ physical activity scores ( = .002) and BBS score ( = .017), and significantly higher TUG time ( < .001) and TSK, FSS, and FIS scores ( = .001, = .001, and = .004, respectively). Individuals with post-LT had lower exercise capacity, physical fitness, balance, and physical activity, and higher kinesiophobia and fatigue levels in the long-term compared to their peers. Future studies should focus on frailty in individuals in the long term after LT.
