Traction is a manual technique that applies force to separate vertebrae and elongate soft tissues in the spine. There are three grades of traction defined by how much the joint surfaces are separated. Traction can be used to restore normal joint range of motion, realign joints, reduce pain, and improve function. It is indicated for conditions like degenerative disc disease, herniated discs, and compression fractures. Contraindications include acute injuries, infections, and vascular problems. The effects include muscle relaxation, relief of nerve pressure, improvement of disc problems, and increased spinal movement.
