Using the Relative Plumb Line<br />
4<br />
Using the AP Connected line and <strong>Posture</strong> Numbertm<br />
Button<br />
PPV uses a multi point plumb line to mark the AP and lateral posture. Using<br />
these two tools we can get an overview of how the patient's posture <strong>com</strong>pares to the<br />
straight line normal profile. Below is how an analysis would look using the standard<br />
angle tools (red lines) and the plumb lines (blue lines)<br />
We know that a plumbline should equally bisect the body in the AP view and should<br />
pass through the ear, center of shoulder, center of hip and just in front of the ankle in the<br />
lateral view.<br />
By creating a Relative plumbline with 4-5 segments, we can see how different parts of<br />
the body relate to each other.<br />
Click on AP Connected Line button. The mouse arrow changes to a crosshair. Now<br />
make four clicks<br />
1. Bridge of nose<br />
2. Episternal notch<br />
3. Belly Button<br />
4. Center of the space between the feet. After last click the line will be drawn.<br />
Lateral Plumbline Points to Click to Get a Person's <strong>Posture</strong> Number tm<br />
Click on Get <strong>Posture</strong> Number button, then make five clicks<br />
1. EAM of ear<br />
2. Center of shoulder<br />
3. Center of hip<br />
4. Center of knee<br />
5. Just in front of ankles. After the last click<br />
the line will be drawn<br />
You can actually perform a <strong>com</strong>plete<br />
lateral exam in this fashion. A<br />
plumb line will be drawn, the pelvic tilt<br />
estimated, the forward head travel calculated<br />
and the additional cervical forces<br />
will be calculated.
