"Physiologists divide nerve-fibers, which form the nerves, into two classes, afferent and efferent. Impressions are made on the peripheral afferent fiber-endings; these create sensations that are transmitted to the center of the nervous system. Efferent nerve-fibers carry impulses out from the center to their endings. Most of these go to muscles and are therefore called motor impulses; some are secretory and enter glands; a portion are inhibitory, their function being to restrain secretion. Thus, nerves carry impulses outward and sensations inward. The activity of these nerves, or rather their fibers, may become excited or allayed by impingement, the result being a modification of functionality – too much or not enough action – which is disease."
Reviews of research studies within the chiropractic community have been used to generate practice guidelines outlining standards that specify which chiropractic treatments are "legitimate" (i.e. supported by evidence) and conceivably reimbursable under managed care health payment systems. Evidence-based guidelines are supported by one end of an ideological continuum among chiropractors; the other end employs antiscientific reasoning and makes unsubstantiated claims. Chiropractic remains at a crossroads, and that in order to progress it would need to embrace science; the promotion by some for it to be a cure-all was both "misguided and irrational". A 2007 survey of Alberta chiropractors found that they do not consistently apply research in practice, which may have resulted from a lack of research education and skills.

Although mixers are the majority group, many of them retain belief in vertebral subluxation as shown in a 2003 survey of 1100 North American chiropractors, which found that 88% wanted to retain the term "vertebral subluxation complex", and that when asked to estimate the percent of disorders of internal organs (such as the heart, the lungs, or the stomach) that subluxation significantly contributes to, the mean response was 62%. A 2008 survey of 6,000 American chiropractors demonstrated that most chiropractors seem to believe that a subluxation-based clinical approach may be of limited utility for addressing visceral disorders, and greatly favored non-subluxation-based clinical approaches for such conditions. The same survey showed that most chiropractors generally believed that the majority of their clinical approach for addressing musculoskeletal/biomechanical disorders such as back pain was based on subluxation. Chiropractors often offer conventional therapies such as physical therapy and lifestyle counseling, and it may for the lay person be difficult to distinguish the unscientific from the scientific.
Utilization of chiropractic care is sensitive to the costs incurred by the co-payment by the patient. The use of chiropractic declined from 9.9% of U.S. adults in 1997 to 7.4% in 2002; this was the largest relative decrease among CAM professions, which overall had a stable use rate. As of 2007 7% of the U.S. population is being reached by chiropractic. They were the third largest profession in the US in 2002, following doctors and dentists. Employment of U.S. chiropractors was expected to increase 14% between 2006 and 2016, faster than the average for all occupations.
After my adjustment, I was seen by a exercise therapist who walked me through a series of exercises to help with my pelvic rotation and weak glute muscles. Chiropractic adjustments combined with an exercise program can be an effective solution for treating sore muscles and joints. Want to try a few of the exercises I did at home? You’ll need a foam roller, an exercise ball and a flexible mini ball.
Studies have not confirmed the effectiveness of prolotherapy or sclerotherapy for pain relief, used by some chiropractors, osteopaths, and medical doctors, to treat chronic back pain, the type of pain that may come on suddenly or gradually and lasts more than three months. The therapy involves injections such as sugar water or anesthetic in hopes of strengthening the ligaments in the back.
