Meta Analysis Comparative Study
[Acupuncture for back pain: meta-analysis of randomised controlled trials and an update with data from the most recent studies].
Acupuncture is commonly used to treat back pain. A meta-analysis of clinical trials of acupuncture for this condition came to a positive conclusion whilst a qualitative review was negative. ⋯ Collectively, these data imply that acupuncture is superior to various control interventions, although there is insufficient evidence to state whether it is superior to placebo.

The aim of the study was to investigate the effects of acupuncture on the affective and sensory experience of pain in chronic pain patients. Furthermore, the study tried to estimate the therapeutical benefit of acupuncture in relation to the stage of chronic pain according to the Mainz pain staging system for chronic pain (MPSS). ⋯ Acupuncture in patients with high-stage chronic pain syndromes preferentially influences the affective dimension of pain perception. For the estimation of the overall clinical outcome of acupuncture treatment, a differentiation between affective and sensory components of pain is recommended.
