“The current study provides the strongest evidence to date that chiropractic care is safe, effective, and results in high levels of patient satisfaction and perceived treatment benefit, thus strengthening our knowledge regarding this conservative nondrug option for low back pain,” Christine M. Goertz, DC, PhD, a chiropractor with the Spine Institute for Quality in Iowa, told Healthline.
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.
Chiropractors use hands-on spinal manipulation and other alternative treatments, the theory being that proper alignment of the body's musculoskeletal structure, particularly the spine, will enable the body to heal itself without surgery or medication. Manipulation is used to restore mobility to joints restricted by tissue injury caused by a traumatic event, such as falling, or repetitive stress, such as sitting without proper back support.
