Chiropractic BioPhysics (CBP®) and Posture
Good or normal posture is a simple matter of engineering. The human body is designed so that the head, rib cage and pelvis are perfectly centered and balanced with each other.
Viewed from the front, the spine is perfectly aligned with gravity. But the spine, when viewed from the side, contains three curvatures to properly balance your body weight and allow freedom of movement.
Abnormal body posture: Below, the green lines on the front and side views represent correct alignment. The red line represents the spine and misalignment of the body due to injury, wear, poor posture or age.
Optimal body posture: The green lines on the front and side views represent gravity and good posture. The green lines of the spine show optimal alignment and curvature seen from the front as a straight line and seen from the side as three curvatures.
