The Tru-Align stretches the spine forward and apart. With repeated use, this encourages misaligned vertebrae to adjust into place, and the disc spaces to increase. This combination reduces pressure on the nerves. Trigger points which are tender knots in the muscles made up of lactic acid (a waste product left over after the muscle burns energy), are also dissolved. When there is pressure on the nerve, the muscles react by “splinting” or “guarding”, tensing up to protect the area. This increases lactic acid production, and when the body reaches overload, painful trigger points are formed. The forward stretching of the spine is passive extension that, not only stretches the muscles and discs apart, but also ends up limbering where the muscles attach to the bones. This is a form of “passive motion therapy”, which causes the stiff scar tissue attachments to become more elastic, resulting in better flexibility and range of motion.
