Spinal traction is a form of decompression therapy for back injuries that creates intersegmental lengthening of the entire spine. This is dependent on the amount of force and the length of time the force is applied. This relieves pain and improves the body, allowing it to heal itself. This is beneficial to patients who suffer from spinal traction is used to treat sciatica, herniated discs, pinched nerves, degenerative disc disease, pinched nerves, and many other back conditions.

The benefits of spinal traction are found in all facets of the back...



Changes according to “Wolff’s Law” occur in response to distraction/compression forces. The major effect on bone comes from increased movement which reverses any immobilization related bone weakness by increasing or maintaining bone density.




Ligament reactions occur as a response to the viscoelastic properties. The amount of ligament deformation with low rate loading, encourages adaptive changes in length and strength. This stretching facilitates proprioceptive nerves, synovial fringes, vascular structures and nerve roots. Activation of the proprioceptive nerves provides pain relief through pain gating effect.




Disc protrusions are positively affected by shifting the fluid dynamics by decreasing the central pressure of weight bearing.

Articular Facets

Articular facets separated through traction. Meniscoid structures, synovial fringes, Osteochondral fragments are decompressed allowing improved synovial fluid permeability. Traction may also decrease the rate of degenerative changes of osteoarthritis. Distraction reduces the rate of proprioceptive discharge resulting pain relief.



Muscle tension is decreased with traction, through increased blood flow and pain gaiting response of proprioceptors.
