ROTATION OF THE PELVIS
If one side front and the other side rear has higher values this is suggestive of Pelvic Rotation. The side with the higher front value may have an Anterior Pelvic Tilt. Lengthening the front of the leg on that side should improve balance.
TILT OF THE PELVIS
If both front values are higher than the rear or rear higher than the front, you likely are looking at Pelvic Tilt. For higher front values work the back of the body, and vice versa for higher rear values.
If there is minimal apparent deviation of the pelvis, the will likely be deviations at the Atlas or in the cranial bone organization. There is a discussion of these issues in this section of papers:
