The sartorius muscle of ten normal subjects was studied by elec-tromyography. It is most active during flexion of the hip and only slightly active during lateral rotation and abduction of the hip. The muscle is usually more active during knee flexion than during extension, but this is not universal. Apparently in some persons it plays a role in knee extension in addition to its knee flexion action, depending on knee position and variations in insertion. Sartorius appears to be a regulator in hip flexion and lateral rotation during the swing phase of gait.
