Physical motor function and nutritional assessments were performed before and 3 to 6 months after the start of the intervention. The Holmʼs multiple comparison procedure was used for the statistical analyses. The patientsʼ quality of life (QOL) was evaluated before and after the intervention and compared using the Wilcoxon signed rank test, with p values of <0.05 considered significant. Physical motor function was assessed based on grip strength (non shunt limb), knee extension muscle strength, toe grip strength, and abduction muscle strength at 3 months after the intervention. The subjects exhibited improvements in muscle strength and the results of the 30 second chair stand test and 6 minute walking test after 3 months, which were maintained after 6 months. No significant changes in nutritional parameters, including the blood hemoglobin concentration, were observed. The QOL evaluation revealed that physical function, mental health, the subjectsʼ overall view of their health, and vitality increased. It is pre-
