Adjustments go by many names: chiropractic manipulation, manual manipulation and spinal manipulation are three common ones. And, actually, all of these are accurate to chiropractic care. Chiropractic care is designed to manipulate, or adjust, spinal joints that are out of alignment or not moving properly. Most chiropractors call these subluxations or, the subluxation complex. They may be causing pain, discomfort or limited range of motion. A vertebra that is not in the right place can affect the bones adjacent to it, as well as muscles in the back, which can cause widespread, agonizing pain.
