Using the Relative Plumb Line 24
Using the AP Connected line and Posture Num-
ber Button
tm
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.
