Analyzing Lateral Cervical Posture (Looking for Translations)

When analyzing lateral cervical posture you are looking for the relationship of the head
and how it is positioned over the shoulder, hips, knees and feet. You have normal posture
when a plumb line passes through the center of the ear and the center of the shoulder,
greater trochanter, knees and ends just in front of the ankle bone. If the head is forward of
this position, it's called an Anterior Translation. If it is behind the neutral position it's called a
Posterior Translation.

Calculating Excessive Cervical Forces

If we know the weight of the head, the length of the muscles attached to it, and the
amount of head movement forward to neutral, we can calculate additional forces placed on
the muscles. Dmitry Esikov, PhD in physics, has developed the formula we use to predict
these additional forces.

Because we must estimate the weight of the head and the length of the muscles, the
formula cannot be 100% accurate. It can be used as a valid reference to show and explain
additional forces placed on the muscles and the spine, and used as a indicator of patient
progress. This amount will appear on the analysis screen and in the report.
