“…the notion that regular chiropractic treatments maintain patients at their optimal level and prevent illness is still a widespread concept in chiropractic. Thousands of websites promote it. Many chiropractors would like to see maintenance care for each patient from the cradle to the grave. This, of course, begs the question whether or not maintenance care is effective. A recent systematic review  found only one pilot study addressing this question. In this trial, 29 back pain sufferers were randomised to receiving either nine months of maintenance therapy or to having no such treatment. The results failed to show any differences in pain at follow-up. Since then no further studies have emerged. This means that no conclusive research on the effectiveness of chiropractic maintenance treatment currently exists.” Professor Edzard Ernst, Pulse (22nd November 2010) [Free registration]
