Over time, scar tissue tends to develop within the soft tissue that is around stuck and misaligned vertebra. Intersegmental traction is a gentle way of helping restore flexibility and strength to these damaged tissues. Modern traction machines allow patients to lie down while being massaged and stretched ever-so-slightly during treatment. These machines increase lymph drainage, relax tight muscles, increase range of motion, and reduce the risk of reinjury to your spine. They can also be used while applying ice or heat to any number or areas.
