Osteopathy and chiropractic in the UK: statutory regulation, evidence and who should take care

The NHS states that osteopaths must be registered with the General Osteopathic Council and chiropractors with the General Chiropractic Council. This is statutory regulation, and it is what separates them from most other complementary practitioners, who the NHS says do not need to be registered by law.

The General Osteopathic Council was established under the Osteopaths Act 1993 and protects the title osteopath, with a public register searchable by postcode or town. The General Chiropractic Council protects the title chiropractor, offers a Find a Chiropractor tool searchable by surname, postcode, registration number or place, and runs a fitness-to-practise process through which patients can raise a concern.

The NHS describes osteopathy as using massage and stretching to treat injuries, improve movement and relieve pain, and chiropractic as using massage and stretching to try to keep bones, joints and muscles healthy. The General Chiropractic Council describes the focus as the spine and musculoskeletal system and associated impacts on health.

Neither page names specific conditions for which the NHS commissions these services, and the NHS says that, unlike acupuncture or Alexander technique, osteopathy and chiropractic are not among the complementary therapies it specifically lists as offered. Availability and cost are therefore mainly a private matter, and the NHS back pain page describes manual therapy involving massage and movement of muscles and joints among options if self-care does not help.

Spinal manipulation is a controlled thrust applied to a spinal joint, and NCCIH notes chiropractors, osteopathic physicians and physical therapists commonly perform it. For acute low-back pain, studies show modest improvements in pain and function comparable to non-steroidal anti-inflammatory drugs, and for chronic low-back pain results are similar to other recommended therapies.

For neck pain it helps acute cases and may help chronic ones, though evidence quality is low to moderate. It may reduce the frequency and intensity of cervicogenic headache and may help migraine, but evidence is preliminary. For non-musculoskeletal conditions, high-quality research is limited and no clear benefit has been shown.

Mild effects such as increased pain, stiffness or headache usually settle within 24 hours, according to NCCIH. It also describes rare but serious risks, including cervical artery dissection, which can cause strokes, and spinal or neurological problems, with higher risk for people with underlying conditions.

The NHS pages for both professions say treatment may be unsafe if you take blood-thinning medicines or are at increased risk of bleeding or stroke, have severely weakened or damaged bones or joints, or have nerve conditions such as peripheral neuropathy. The same applies if you have a clinical reason for caution that has not been discussed, so give a full history.

• Call 999 for sudden severe headache, loss of vision, slurred speech, facial weakness or limb weakness after neck treatment.

• Seek emergency care for back pain with tingling, weakness or numbness in both legs, or numbness around the genitals or anus.

There is no reliable basis in these sources to say one profession is better than the other, and treatment styles vary between individual practitioners. NCCIH advises verifying education and licensure, disclosing your complete health history and all medications, and discussing session frequency and cost beforehand.

Search the relevant register to confirm that the person is registered, and ask what they would do if you do not improve within a few sessions. If a practitioner recommends long prepaid courses, or claims to treat conditions unrelated to the musculoskeletal system, ask for the evidence.
