                        PP8 uses a multi point plumb line to mark the AP and lateral posture. Using
                   these two tools we can get an overview of how the patient's posture compares to the
                   straight line normal profile. Below is how an analysis would look using the standard
                   angle tools (red lines) and the plumb lines (blue lines)





























                    We know that a plumbline should equally bisect the body in the AP view and should
               pass through the ear, center of shoulder, center of hip and just in front of the ankle in the
               lateral view.


                    By creating a Relative plumbline with 4-5 segments, we can see how different parts of
               the body relate to each other.
