What happens when a disc loses fluid?
When a disc loses too much fluid, it becomes dehydrated and painful. With N.D.R., intradiscal fluid exchange is increased from negative to positive, bringing more fluid back into the disc. To continue our previous analogy, if we put air back into a tire, it resumes its normal shape and size. This is similar to N.D.R., which brings fluids back into the disc so the disc can regain its normal shape, size and function.
