Just as there are normal values for heart rate, blood pressure, and any other physiological parameter, there is also a normal standing posture and spinal position. The normal posture is one that has the head, rib cage, pelvis and feet aligned and balanced upon the other, both from the front and side views. Your posture is the ‘Window into your Spine' as it is inside of your posture and responsible for its alignment. The spine should be straight and vertical from the front. From the side the spine should have normal alternating curves to allow for normal pain-free, maximal range of motion and movement.

 

From the front the posture is symmetric and the spine is straight. From the side view, the head, rib cage, pelvis and feet are vertically balanced. The spine has essential curves in the side view. These curves have specific normal angles that can be measured from x-rays.
