Personal success stories aside, literature is full of research and testimonials that back the efficacy of chiropractic care: In a randomized controlled trial published in the British Medical Journal in 2003, 183 patients with neck pain were randomly allocated to manual therapy (spinal manipulation), physiotherapy (exercise), or general practitioner care (counseling, education and drugs.) Within the first 26 weeks, “the manual therapy group showed a faster improvement than the physiotherapy group and the general practitioner care group.”  The study concluded with, “The cost effectiveness ratios and the cost utility ratios showed that manual therapy was less costly and more effective than physiotherapy or general practitioner care.”          Korthals-de Bos et al (2003), British Medical JournalThe American College of Physicians has repeatedly and consistently supported non surgical and nonpharmacologic treatments for acute and subacute low back pain:"For patients with chronic low back pain, clinicians and patients should initially select nonpharmacologic treatment with exercise, multidisciplinary rehabilitation, acupuncture, mindfulness-based stress reduction (moderate-quality evidence), tai chi, yoga, motor control exercise, progressive relaxation, electromyography biofeedback, low-level laser therapy, operant therapy, cognitive behavioral therapy, or spinal manipulation (low-quality evidence)." American College of Physicians (2017)The NIH’s National Center for Complementary and Alternative Medicine has funded many studies about the effectiveness of spinal manipulation to treat pain. In this 2012 study, the NIH targeted different approaches for treating acute and subacute neck pain:“272 persons aged 18 to 65 years who had nonspecific neck pain for 2 to 12 weeks were divided into three groups: one group received spinal manipulation therapy from a doctor of chiropractic (DC): one group received pain medication (over the counter pain relievers, narcotics and muscle relaxants): and one group received exercise recommendations. After twelve weeks, spinal manipulation showed a clear significant and statistical advantage over pain medication. “The primary outcome was participant-rated pain, measured at 2, 4, 8, 12, 26, and 52 weeks after randomization.”  Bronfort et al.
