Objectives: To investigate the relationship between the psoas muscle cross-sectional area and physical performance in patients with liver cirrhosis.
Methods: This study analyzed ambulatory patients with liver cirrhosis aged < 65 years, who underwent abdominal computed tomography (CT) and Short Physical Performance Battery (SPPB) tests from December 2018 to December 2019. A total of 46 patients (36 men, 10 women) were included. In abdominal CT scans, the psoas muscle cross-sectional area (mm2 ) was measured at the distal end-plate level of the L4 vertebral body and normalized by dividing by height (m). Physical performance was evaluated using SPPB. A correlation analysis between the psoas muscle cross-sectional area and SPPB was performed. Kruskal-Wallis test was used to determine differences in the psoas muscle cross-sectional area and SPPB according to the Child-Pugh classification. Multiple regression analysis was performed to determine factors affecting SPPB.
Results: The correlation coefficient between the psoas muscle cross-sectional area and SPPB was 0.459 at the P < 0.01 level. No difference was observed in the psoas muscle cross-sectional area and SPPB according to the Child-Pugh classification. The psoas muscle cross-sectional area was a factor affecting SPPB in multiple regression analysis.
Conclusions: Abdominal CT is an essential diagnostic tool in patients with liver cirrhosis. Ambulatory patients with liver cirrhosis aged < 65 years could have reduced physical performance. In this study, the psoas muscle cross-sectional area was correlated with physical performance and was a factor affecting physical performance. The psoas muscle cross-sectional area and physical performance should be evaluated in patients with liver cirrhosis.
