Chiropractic care is an alternative medical approach that consists of a specialist correcting “subluxations,” which occur when the vertebrae in your spine shift, leading to pain and pinched nerves.
A chiropractic adjustment or alignment is a quick maneuver in which a force is applied to a joint in a specific vector or line. The joint is pushed past restricted ranges of motion but not far enough to cause any damage or dislocate the joint  . This dynamic thrust of sudden force may be accompanied by an audible release and is intended to increase range of motion  , reduce pain and improve performance.
The points of the body where two bones come together are called “Joints.” These joints have two main functions: allow mobility of the skeletal system and to provide a protective enclosure for vital organs. 
There are a variety of reasons why joints to lose their normal function and motion.
D.D. Palmer hypothesized that these small misalignments impeded the body’s functions; specifically, the ability to self-heal  .
Chiropractic care aims to prevent or reduce pain and injury, increase or restore range of motion, improve joint function, aide the nervous system  and increase performance; while keeping treatment conservative and trying to avoid excessive drugs, surgery or other more invasive measures.
Chiropractic has been in the United States, Canada, and Australia for many years  . In 1896, D.D. Palmer was working in his office in Davenport, Iowa when he came across the building’s janitor, Harvey Lillard. Mr. Lillard had severe hearing problems. Palmer had a theory that there was a connection between Mr. Lillard’s hearing problems and a lump in his back  ; so, when Palmer treated Mr. Lillard  , his hearing was restored and chiropractic was born  .
Typically, chiropractic care uses a combination of manual manipulation and exercise therapy to get to the root of the problem, so you no longer have pain and are able to move comfortably.
