There are seven vertebrae that are the bony building blocks of the spine in the neck (the cervical vertebrae) that surround the spinal cord and canal. Between these vertebrae are discs, and nearby pass the nerves of the neck. Within the neck, structures include the skin, neck muscles, arteries, veins, lymph nodes, thyroid gland, parathyroid glands, esophagus, larynx, and trachea. Diseases or conditions that affect any of these tissues of the neck can lead to neck pain.
Doctors of Chiropractic (DCs) – often referred to as chiropractors or chiropractic physicians – practice a hands-on, drug-free approach to health care that includes patient examination, diagnosis and treatment. Chiropractors have broad diagnostic skills and are also trained to recommend therapeutic and rehabilitative exercises, as well as to provide nutritional, dietary and lifestyle counseling.
Numerous controlled clinical studies of treatments used by chiropractors have been conducted, with conflicting results. Systematic reviews of this research have not found evidence that chiropractic manipulation is effective, with the possible exception of treatment for back pain. A critical evaluation found that collectively, spinal manipulation was ineffective at treating any condition. Spinal manipulation may be cost-effective for sub-acute or chronic low back pain but the results for acute low back pain were insufficient. The efficacy and cost-effectiveness of maintenance chiropractic care are unknown. There is not sufficient data to establish the safety of chiropractic manipulations. It is frequently associated with mild to moderate adverse effects, with serious or fatal complications in rare cases. There is controversy regarding the degree of risk of vertebral artery dissection, which can lead to stroke and death, from cervical manipulation. Several deaths have been associated with this technique and it has been suggested that the relationship is causative, a claim which is disputed by many chiropractors.
