    Muscle abbreviations are listed in Table 1.

    Flex, flexion of the knee; ext, extension; retraction, femur retraction; post rotation, clockwise long-axis femur rotation as seen in right lateral view; elevation, femur elevation.

  • a Each variable is a combination of a muscle and a phase of the stride. The description following the muscle abbreviation (e.g. stance flex) indicates the percentage of the total rectified integrated area of those muscles during those kinematic events.
