A chiropractic adjustment is the art of using a specific force in a precise direction applied to a joint that is subluxated, fixated, "locked up", or not moving properly. This frees the subluxation, restores normal function to the nervous system, adds motion to the joint, allowing the bones to gradually return to a more normal position and motion. The purpose of this safe and natural procedure is improved nerve and spinal function, thus improved health.There are many ways to adjust the spine. Usually the doctor's hands or a specially designed instrument delivers a brief and highly-accurate thrust. Some adjusting methods are quick, whereas others require a slow and constant pressure.After years of training and clinical experience, each chiropractic doctor becomes highly skilled in the delivery of a variety of adjusting approaches.
