From the Guardian: Tony Metcalfe, president of the British Chiropractic Association, said that because the study had only looked at 15 Australian physiotherapists, direct comparisons could not be made with UK practitioners of spinal manipulative therapy.
"The study did not address chiropractic-only spinal mobilisation carried out by physiotherapists. The majority of participants had low velocity mobilisation techniques and only 5% experienced high velocity techniques. Chiropractic manipulation is based predominantly on high velocity techniques, so the results are therefore not comparable with chiropractic treatment."
Chiropractors and osteopathic physicians, aka osteopaths or D.O.s, use high velocity techniques. If your joints are misaligned, you can get instant relief.
I’ve never had any complaint about their treatments.
