| Research Abstract |
The present study aimed to develop an ultrasonographic method for estimating the cross-sectional area of the psoas major muscle. The muscle cross-sectional area (CSAMRI) and thickness (MTMRI) of the psoas major muscle at L4-L5 were measured using MRI in 11 healthy sedentary men. Ultrasonographic images of muscle thickness (MTUS) were obtained at the corresponding sites. There was no significant difference between MTMRI and MTUS. CSAMRI was significantly correlated to MTUS. The interclass correlation coefficient of MTUS measurements performed on two separated days was 0.951. The current results indicate that the psoas major muscle thickness determined by the ultrasonographic method is useful for estimating the cross-sectional area of the psoas major muscle.
