Scanning posture maps: (A) shows supine adduction (feet together and perpendicular to the bed surface); (B) shows adduction and outward rotation of 30° (feet together, toe outward rotation of 30°); (C) shows the 30° internal rotation position (foot abduction and shoulder width, toe inward rotation of 30°); (D) shows supine flexion at 30° (hip flexion and knee flexion, thigh and bed surface are 30°); (E) shows 30° back extension in the prone position (knees, ankles, and feet together; 30° back extension of the thighs with a 30° wedge pad on an inclined plane and bed).
