To understand how chiropractic care is beneficial, we need to understand some of the nerve, spinal cord, and brain function. The central nervous system which is the brain and spinal cord runs the physical body. All functions of the body is directed by the nervous system including healing and maintenance of health. The spinal cord is a nervous conducting mechanism but embedded in the nerves are programmed patterns of movement. The nervous system monitors and modulates all sensory input from the internal and external environment, integrates this information with older learned experiences and then responds in an electrical or chemical means to produce a response or motor output for the preservation of the organism. Consequently the central nervous system is driven by the environment. Internal or external environmental inputs into the system dictates the response needed by the organism or the species to survive and propagate.
The environment input is received through receptors that convert external or internal stimulus to an electrical impulse. For instance light is converted in the eye or sound is converted in the ear to an electrical impulse. This impulse goes centrally through the nervous system and diverges upon many nerves some excitatory and some inhibitory. The sum of all the excitatory and inhibitory stimulation on a nerve determines whether the nerve will fire to conduct the impulse or not. There may be as many as 10,000 nerves contributing to a single nerve to determine if it will fire or not. Around 95% of the environmental input is from motion, the horse and all organisms are constantly under a force requiring motion to counteract it. The major environmental force is gravity. The organism only has two output system from the brain to ensure survival in response to the external and internal environment. One system is the motor output system to the muscle. The other is to the autonomics system which controls organ system function like heart rate, glucose availability, or carbon dioxide elimination.
Since most injuries are due to a failure of muscles to fire at the right time and amplitude to support a joint against the forces of motion and gravity and all healing involves the immune system each activity is directed by the nervous system. As a result all disease is a breakdown in the efficiency of the nervous system to maintain homeostasis under the organism’s present genetic and environmental constraints. So it does not matter what treatment modality you are employing: nutrition, drugs, acupuncture, or manipulation therapies, we are influencing the nervous system and its output function on the organism.
Joint Motion Not Bone Out of Place
Consequently since motion is the largest percent of influence on the nervous system and output function, improving the movement of a joint or motion unit can offer the largest effect on the nervous system and its stimulated end function. The improvement of the nervous system function can occur in two ways. One as we have discussed, improving motion of a joint increases the sensory input into the nervous system to affect a nervous response. Also since the spinal nerve exits the spinal cannel through a boney tunnel, the nerve is subject to compression forces. Where do these forces come from? When motion decreases, stasis occurs in the tissue there by allowing fluid to accumulate. As the fluid in the boney tunnel takes up the limited space in the tunnel other structures in that confined area are compressed. Therefore a compressed nerve has a decrease in its conducting ability; so whatever body structure or function is directed by that particular nerve will have a decreased stimuli to direct the desired response.
So as you can see neural function modulates all body functions through two output system, motor and autonomic. The nervous system responds to the environment and is driven by internal or external stimuli through receptor input. Motion especially in counteracting gravity accounts for about 95% of the input into the nervous system. An improvement to input into the nervous system along with an improvement in outflow of the nervous system will improve the function of the organism. This desired improvement can be accomplished with a chiropractic treatment by increasing movement of the motion unit which increase input into the system and disperse the fluid accumulation allowing nerve function to improve.
