Millions of U.S. adults would choose chiropractic care first to treat neck or back pain, according to a 2014 nationwide survey. The Gallup-Palmer report revealed 57% of all U.S. adults believe in the effectiveness of treatment and are likely to visit a chiropractor. Over 50% of adults have visited a chiropractic doctor in the past, and over 25% would choose a chiropractor over any other type of doctor if they experienced back or neck pain. The nationally representative survey, commissioned by the Palmer College of Chiropractic in Iowa, also found that more adults are seeking chiropractic treatment than previously estimated. The survey found that 33.6 million Americans visited a chiropractor in 2014, up from the 2012 estimate of 20.6 million Americans. Chiropractic care takes a trained, conservative approach to the treatment of neuromusculoskeltal concerns, limiting the need for prescription painkillers or surgery. However, about four in ten U.S. adults reported concerns about cost, and nearly half did not know whether their insurance plan covered chiropractic services. According to the American Chiropractic Association (ACA), numerous recent studies refute these misconceptions. The ACA reports that chiropractic care is at least partially covered by most insurance plans and is considered a cost-effective form of treatment for back and neck pain.
