What chiropractors can help with – and what patients should know

Chiropractors offer a range of services, primarily focused on musculoskeletal issues, particularly back pain. According to recent data, around 11 percent of adults in the United States visited a chiropractor in 2022, largely for pain relief. This reflects a growing acceptance of chiropractic care within mainstream healthcare, with many major health systems incorporating these services. However, the profession still faces skepticism due to historical perceptions and ongoing debates over the scientific validity of certain treatments. The history of chiropractic care dates back to the late 19th century, when D.D. Palmer, the profession's founder, famously claimed to restore hearing to a man by adjusting his neck. This story, while controversial, contributed to the early mystique surrounding chiropractors. Over time, the field has evolved, with practitioners undergoing formal education and training. In the U.S., aspiring chiropractors complete a four-year program that includes coursework in basic sciences, nutrition, and lifestyle counseling. They also receive extensive training in performing manual adjustments, which involve applying pressure to joints to relieve tension in the muscles connected to the spine. William Lauretti, a professor at Northeast College of Health Sciences and a representative of the American Chiropractic Association, explains that the popping sound often associated with these adjustments is caused by the release of gases from joint fluids. While this sound may be satisfying to patients, it is not the primary objective of the procedure. After completing their education, chiropractors must pass a national board exam to qualify for state licensure. The scope of their practice varies depending on the jurisdiction, with some states allowing additional responsibilities such as delivering babies or performing minor surgical procedures. Insurance coverage for chiropractic services differs by region and provider. Many insurance plans include coverage for adjustments, nutritional counseling, and diagnostic imaging like X-rays. Medicare, however, offers more limited coverage, typically restricting reimbursement to spinal adjustments alone. Chiropractors are actively working with lawmakers to expand Medicare coverage to include a broader range of services. Research indicates that chiropractic care can be beneficial for specific conditions. Christine Goertz, a professor at Duke Clinical Research Institute and a licensed chiropractor, notes that there is substantial evidence supporting the effectiveness of manual manipulation in managing lower back pain. A review of 47 randomized controlled trials found that chiropractic adjustments were comparable in efficacy to treatments such as acupuncture and massage therapy. These findings align with recommendations from organizations like the World Health Organization and the Department of Veterans Affairs, which consider spinal manipulation a viable initial treatment option for lower back pain. Despite these positive outcomes, concerns remain regarding the safety and scientific basis of some chiropractic practices. Critics argue that a minority of practitioners may promote treatments lacking empirical support, such as using chiropractic care for conditions like diabetes or asthma. The American Chiropractic Association acknowledges that while most professionals adhere to evidence-based methods, there are instances where alternative approaches are employed. Patients are advised to seek care from qualified professionals and to discuss the potential benefits and limitations of various treatments before proceeding.
