Since discs have a poor blood supply, they get nutrients from the circulation of fluids surrounding spinal joints. Fixations prevent this natural circulation and can cause disc thinning and degeneration. Intersegmental traction helps increase and restore necessary elasticity and motion to the spine.

There are various ways of applying Intersegmental Traction. The two most common are motorized and manual. The manual form allows for more specific treatment and greater control. Traction of this type is utilized successfully in the treatment of herniated discs. It is also excellent for the older patient who may not be able to handle regular spinal manipulation.

Intermittent traction relieves muscle spasm, reduces swelling, improves circulation in the tissue, and prevents formation of adhesions between the dural sleeves of the nerve roots and the adjacent capsular structures.
