During October 2010 the UK General Chiropractic Council updated its evidence on sciatica from inconclusive but favourable, to a moderate level of positive evidence when compared to sham manipulation following a review by Professor Bronfort of the Santilli et al trial which was included within a 2008 literature synthesis conducted by Lawrence et al on the chiropractic management of low back pain and low back-related leg complaints.  However, the author of a well respected evidence summary maintains the following:

"There is no reliable evidence that chiropractic, osteopathy, or spinal manipulation provide any useful benefit for people with sciatica. And there is reason to believe that chiropractic may aggravate sciatica.  I have a double personal interest in this issue because (i) I have sciatica, and (ii) I wrote this evidence summary. The evidence was summarised last year, but our scanning for new research has not found any new evidence since then, as you can see here.  The abstract of this recent paper is consistent with what I have said, and tells you all you need to know about the evidence: there is no effective treatment other than surgery (when the sciatica is due to nerve root compression) --- and surgery has its limitations too."   Michael Power (20th October 2010)
