Schematic representation of body angles. In lateral view photographs (left), NF (neck flexion) angle was defined as the angle between two intersecting lines: a line connecting the external acoustic foramen and the acromion, and another line connecting the acromion and the greater trochanter. Similarly, FB (fore-bent) angle was defined as the angle between a vertical line and the line connecting the acromion with the greater trochanter. KB (knee-bent) angle was defined as the angle between the line connecting the greater trochanter and knee, and the line connecting knee and lateral malleolus. In back view photographs (right), LB (lateral-bent) angle was defined as the angle between a vertical line and the line connecting the posterior process of the seventh cervical vertebra with that of the fifth lumbar vertebra
