Neck pain can be caused by a variety of factors, such as an accident, injury, overuse, or vertebral misalignment. The efficacy of chiropractic for neck pain has been well documented in countless studies conducted worldwide.
In a joint U.S./Canadian study, researchers from UCLA, the West LA Veterans Affairs Medical Center, and two chiropractic colleges found that for some patients with sub-acute or chronic neck pain, spinal adjustment proved to be a more effective treatment than mobilization or physical therapy.
In a study conducted by the Canadian Memorial Chiropractic College in Toronto researchers found spinal adjustments to improve neck mobility and decrease neck pain. An additional Canadian investigation published in 1997 by the University of Calgary found spinal adjustments to improve neck mobility and decrease neck pain in patients having back and/or neck complaints.
General practitioners in private practice at the Welsh National School of Medicine conducted a study of the efficacy of spinal adjustment in alleviating neck and shoulder pain. The results,indicated that pain and discomfort improved significantly after adjustment, as well as range of motion and flexibility of the affected areas.
A Netherlands study conducted by doctors of medicine and other professionals investigated different methods of treatment for patients with chronic back and neck pain. After 12 weeks of care, manual therapy (which consisted of adjustment and mobilization of the spine) had showed a "faster and larger improvement in physical functioning" relative to the other types of treatment such as massage, exercises, and physical therapy.
