The brain and spinal nerves communicate position sense and balanced equilibrium.  Nerve interference cause unequal weight distribution, disharmony and stress to the body, muscles and joints.   There two things that happen when you have a bone out of place in the spine.  First, when the bone is out of place and twists the spine, it pinches the nerve.  That doesn’t cause pain.  It causes weakness.  You have an energy, brain waves, that flow from above down, inside out, that comes from your brain through the spinal cord.  If you’re choking off that nerve flow, whatever that nerve is going to will be weakened.  The other thing that happens is that when the bone is out of place, it’s like having the front end of your car misaligned; the tires or axle wears out.
