Role of Posture and the Disc

CREEP

1. Displacement of the nucleus pulposus and not the annulus

2. Occurs most within the first 3 minutes of asymmetrical loading

-continues for several hours as slower rate


3. If the loading is constant, then the nucleus may remain in the constant displaced position

-unless the disc has reached its physiological limits, the constant displacement is reversible


4. Creep also has affect on ligaments

-sustained stretch reduces ligmament function


5. Axial creep

-10% reduction in disc height
-1-2% total height
-Because of increase fluid in the disc in AM flexion causes increase in discal pressure of greater the 300%
