Traction is a form of decompression therapy that relieves pressure on the spine and alleviates pain from joints, sprains, and spasms. It can also treat herniated discs, sciatica, degenerative disc disease, pinched nerves, and many other back and neck conditions. Traction is performed by skilled physical therapists and/or the use of mechanical units.
Cervical (neck) traction and lumbar (low back) traction are similar, but they have a couple of key differences: with cervical traction, a gentle force is used to stretch or pull the head away from the neck. With lumbar traction, a gentle force is used to gently gap the pelvis from the lower back. Both of these methods are useful in manipulating the spine and providing relief.
