When spinal joints are irritated, the postural muscles around the spine react by going into spasm or guarding against further injury. When regular traction is applied to a joint, the body’s normal reaction is to pull in the opposite direction. Welcome Back’s Antalgic-Trak spinal decompression unit, the first in Toronto, contains a sensitive  computer feedback mechanism to overcome this phenomenon. This allows the applied distraction forces to create a negative pressure inside the disc that, over time, helps to increase the disc height, relieve pressure on the nerves and reduce bulging discs.
