Intersegmental traction is a therapy utilized by chiropractors to induce passive motion into the spine to stretch spinal joints, which increases mobility, allowing the chiropractor to achieve a more effective adjustment. A patient simply lies upon the table face up while roller-type cams move beneath them. The rollers travel the length of the spine slowly stretching it to mobilize and decrease the pain by relaxing the patient. Intersegmental traction can be very helpful in disc injuries as well by providing them with movement and improving elasticity. Discs have a very poor blood supply and fluids are circulated by movement, which provide discs with nutrients to help in the healing process. Fixations in circulation causes discs to thin and degeneration to occur early.
