One thing about Intervertebral Disc Physiology is very clear: Without motion, the disc deteriorates. Without good movement, many problems develop: the disc pH increases, joints stiffen, ligaments shorten, bone density decreases, muscles become deconditioned. Recent evidence suggests that a damaged disc becomes more acidic and that the reduced pH is a mediator of spinal pain.
The adult disc is avascular and it depends on diffusion for its nutrition and exchange of waste products. Diffusion is facilitated by a PUMPING ACTION, through spinal motion. Lack of motion hinders diffusion.
