It always amazes me that such a simple concept, can be so misunderstood. The Science and Philosophy of Chiropractic can be explained in 60 seconds. Maybe, it is the sheer simplicity of it that makes it so unbelievable to people who have not experienced it for themselves.
The Brain has in it, an inborn intelligence that controls the body. The brain sends signals down through the spinal cord, out through the nerves, to every cell, tissue and organ in the body. As long as the messages can successfully travel back and forth between the mind and the body, your body can function properly, and you can be healthy. When the body is healthy, there should be no symptoms or "warning signs" from the body, such as pain.
Stress in life (physical, chemical, or emotional) can cause the spine to move out of place and pinch on the nerves. When this happens, there is interference in the communication between the mind and the body. As such, the body can no longer function with maximum efficiency, and problems begin to develop. eventually, when the problem becomes bad enough, you may experience warning signs such as pain.
A Chiropractor is trained to detect these misalignments and re-align the body. When the body is put back in the "normal" position, it begins to function properly. When the body is functioning properly, there is no need for warning signs, and pain disappears on it's own. The body heals itself, as long as there is no interference in the system. Chiropractors gently remove interference. It is as simple as that!
