The Nerve Assist was actually developed as a favor to chiropractors, many of whom now use it. In our theory, it is nerves that hold the muscles tense, which then hold the spine out of place. There are twelve big nerves which run down a person's spine, spreading out from the spine across both sides of the shoulders and back. These twelve nerves branch out into smaller nerve channels and nerve endings. Nerves affect the muscles and can, if continually tensed, pull the spine and other parts of the body structure out of place.
Nerves carry the shock of impacts.
Such a shock should dissipate, but it seldom does entirely. Nerves give orders to muscles. With an impact, a surge of energy starts down the nerve channels. Then, from the small ends of the nerve channels, the energy surge reverses and the result is a bulge of energy which stops midway along the channel. It is just standing there, not going anywhere.
