Background: Several studies describe poorer motor developmental motor outcomes post‐liver transplant (LT) in younger children. Limited studies examine physical function in older children and adolescents pre‐ and post‐LT. Methods: Retrospective review of standard of care physical function outcome measures pre‐ and 1‐year post‐LT in children ≥6 years at LT. Measures include: 6‐minute walk test (6MWT), grip strength, Bruininks‐Oseretsky Test of Motor Proficiency‐2 (BOT‐2) components, Physical Activity Questionnaire (PAQ), and Paediatric Quality of Life Multidimensional Fatigue Scale. Association of medical variables with outcomes was explored. Results: The study cohort included 23 (8 male, median (interquartile range) age 11.67 (8.25, 13.92) years at LT) participants. Top two primary diagnoses included biliary atresia (30.4%) and fulminant hepatic failure (21.7%). At 1‐year post‐LT, over one‐third (36%) were overweight or obese. Compared with healthy norms, children had significantly lower pre‐LT PAQ scores (p =.002), pre‐ and post‐6MWT scores (p <.001) and post‐LT BOT‐2 strength and agility scores (p <.001). Pre‐LT, lower balance scores were associated with abdominal distention/ascites (p =.009) and splenomegaly (p =.017). Lower pre‐LT platelet count correlated with poorer balance (r =.532, p =.017) and lower strength and agility scores (r =.446, p =.043). Significant moderate inverse correlations were found between weight/body mass index z‐scores and BOT‐2 components. Post‐LT children continue to demonstrate decreased levels of motor proficiency and functional capacity but report less fatigue and increased physical activity. Conclusions: Older children and adolescents undergoing LT are at risk of decreased physical function, highlighting the need for pre‐ and post‐LT rehabilitation to optimize long term outcomes.
