Chiropractors emphasize the conservative management of the neuromusculoskeletal system without the use of medicines or surgery,  with special emphasis on the spine.  Back and neck pain are the specialties of chiropractic but many chiropractors treat ailments other than musculoskeletal issues.  There is a range of opinions among chiropractors: some believed that treatment should be confined to the spine, or back and neck pain; others disagreed.  For example, while one 2009 survey of American chiropractors had found that 73% classified themselves as "back pain/musculoskeletal specialists", the label "back and neck pain specialists" was regarded by 47% of them as a least desirable description in a 2005 international survey.  Chiropractic combines aspects from mainstream and alternative medicine, and there is no agreement about how to define the profession: although chiropractors have many attributes of primary care providers, chiropractic has more of the attributes of a medical specialty like dentistry or podiatry .  It has been proposed that chiropractors specialize in nonsurgical spine care, instead of attempting to also treat other problems,   but the more expansive view of chiropractic is still widespread.
