The Chiropractor's Role By definition, health is the optimal state of physical, mental and social well-being not just the absence of disease or infirmity. The dictating factor of health is 100% coordinated functioning of all the systems and tissues of the body. The controller of the functioning is the nervous system. The purpose of the spine and nervous system is to control and co-ordinate the function of every tissue, every organ and every system in your body and to adapt you to your environment and to fully express your life force. Therefore, if there is any interference affecting the nerve system, whatever is at the other end of those nerves that have been affected is simply not going to function normally. The role of the chiropractor is to find that interference and to reduce or eliminate it if possible, so your body can function as optimally as possible and so that you can be as healthy as possible.
