Acupuncture for low back pain.
BACKGROUND
Although low back pain is usually a self-limiting and benign disease that tends to improve spontaneously over time, a large variety of therapeutic interventions are available for the treatment of low back pain.


OBJECTIVE
The objective of this review was to assess the effects of acupuncture for the treatment of non-specific low back pain.


METHODS
We searched the Cochrane Complementary Medicine Field trials register, the Cochrane Controlled Trials Register (1997, issue 1), Medline (1966 - 1996), Embase (1988 - 1996), Science Citation Index and reference lists of articles.


METHODS
Randomised trials of all types of acupuncture treatment that involves needling for subjects with non-specific low back pain.


METHODS
Two reviewers blinded with respect to authors, institution and journal independently assessed trial quality and extracted data.


RESULTS
Eleven trials were included. The methodological quality was low. Only two trials were of high quality. Three trials compared acupuncture to no treatment, which were of low methodological quality and provide conflicting evidence. There was moderate evidence from two trials that acupuncture is not more effective than trigger point injection or transcutaneous electrical nerve stimulation (TENS). There was limited evidence from eight trials that acupuncture is not more effective than placebo or sham acupuncture for the treatment of chronic low back pain.


CONCLUSIONS
The evidence summarised in this systematic review does not indicate that acupuncture is effective for the treatment of back pain.
