More than 90 patients with back pain lasting from 2-4 weeks were randomly allocated either usual GP type care or a package of care , including 4 weeks of manipulation, delivered by chiropractors. The group treated by the chiropractors had significantly less disability.
This echoes other studies going back to 1990 when the Medical Research Council compared chiropractic care to medical care including physiotherapy. Here too the results favoured chiropractic in the treatment of back pain. In the conclusion of this research the authors suggested that chiropractic should be included on the NHS. 21 years on little has changed.
