The World Health Organization found chiropractic care in general is safe when employed skillfully and appropriately. There is not sufficient data to establish the safety of chiropractic manipulations. Manipulation is regarded as relatively safe but complications can arise, and it has known adverse effects, risks and contraindications. Absolute contraindications to spinal manipulative therapy are conditions that should not be manipulated; these contraindications include rheumatoid arthritis and conditions known to result in unstable joints. Relative contraindications are conditions where increased risk is acceptable in some situations and where low-force and soft-tissue techniques are treatments of choice; these contraindications include osteoporosis. Although most contraindications apply only to manipulation of the affected region, some neurological signs indicate referral to emergency medical services; these include sudden and severe headache or neck pain unlike that previously experienced. Indirect risks of chiropractic involve delayed or missed diagnoses through consulting a chiropractor.
Headache. A 2011 systematic review found evidence that suggests that chiropractic SMT might be as effective as propranolol or topiramate in the prevention of migraine headaches. A 2011 systematic review found evidence that does not support the use of SM for the treatment of migraine headaches. A 2006 review found no rigorous evidence supporting SM or other manual therapies for tension headache. A 2005 review found that the evidence was weak for effectiveness of chiropractic manipulation for tension headache, and that it was probably more effective for tension headache than for migraine. A 2004 Cochrane review found evidence that suggests SM may be effective for migraine, tension headache and cervicogenic headache.
Employment of chiropractors is projected to grow 12 percent from 2016 to 2026, faster than the average for all occupations. People across all age groups are increasingly becoming interested in integrative or complementary healthcare as a way to treat pain and improve overall wellness. Chiropractic care is appealing to patients because chiropractors use nonsurgical methods of treatment and do not prescribe drugs.
The treatment plan may involve one or more manual adjustments in which the doctor manipulates the joints, using a controlled, sudden force to improve range and quality of motion. Many chiropractors also incorporate nutritional counseling and exercise/rehabilitation into the treatment plan. The goals of chiropractic care include the restoration of function and prevention of injury in addition to back pain relief.
