 === Normalizing the Pelvis Angle ===
-Normalizing the Pelvis Segment Angle. The Coda and Helen Hayes pelvis are tilted forward approximately 20 degrees from the horizontal. In describing the orientation of the pelvis or for describing the hip joint angle, it is often convenient to define a pelvis angle that has a coronal plane parallel to the floor (eg a vertical segment with zero tilt).

 === Computing the Range of Motion ===
-The Pelvis Angle typically refers to the orientation of the Pelvis relative to the Laboratory.
+The range of motion of the pelvis angle is commonly defined as the range of each component of the segment angle. While this isn't mathematically correct because joint angles are not vectors, it is still quite common.
